AAK Hydraulic pressure control valves durability for 450bar over 1 year

Erik compared more than 20 hydraulic pilot pressure control valve factories. No manufacturer can do the hydraulic pilot operated pressure control valves which can be used under high pressure above 450bar for more than one year. AAK hydraulic pilot operated pressure control valve passes the test at one time, and there is no abnormality after one year of use. Erik is from a German hydraulic equipment manufacturer. In the first half of last year, the company needed to purchase a special hydraulic pilot operated pressure control valve with a working pressure of more than 450 bar, a service life of more than one year and a durability of more than 2 million times. The boss realized that it was some difficult to purchase the hydraulic pilot operated pressure control valve this time, and asked Erik and his colleague to purchase at the same time. Whoever successfully purchased the hydraulic pilot operated pressure control valve first will be promoted and raised. Erik is full of energy and keeps looking for hydraulic pilot operated pressure control valve factories online and offline. He contacted more than 20 new suppliers, including AAK hydraulic valve. Most of the hydraulic pilot operated pressure control valve manufacturers replied that they need to be customized from the beginning of materials, and it takes 25 days to sample this special hydraulic pilot operated pressure control valve. Erik chose two factories to test the samples. A month later, Erik received the samples and asked the engineer to test them. The results failed, but the hydraulic pilot operated pressure control valve obtained by his colleague passed the first test, which made Erik very depressed. Fortunately, this is just in the test stage, the final effect depends on the test results of the hydraulic pilot operated pressure control valve one year later. Erik contacted AAK for the second time. He clearly informed that the samples of hydraulic pilot operated pressure control valves he selected in the first round failed. For the first time, he did not choose AAK because AAK needed 35 days. This time, he only asked AAK to make samples. Whether he can win or not, he can only count on AAK. Because the material selection and internal test of hydraulic pilot operated pressure control valves need time, Erik also understands the difficulties of making the samples. After 35 days, AAK sent 6 samples of hydraulic pilot operated pressure control valves. Last week, almost a year after the hydraulic pilot operated pressure control valve samples were sent, Erik sent an email to inform that AAK hydraulic pilot operated pressure control valve was the only sample that passed 2 million tests, and there was no abnormality after one year of use. Although his colleague's sample passed the early test, it could not withstand the high pressure above 450 bar for enough time, it leaked in less than a year. A few days ago, the boss praised Erik's purchasing ability at the company conference, and his dream of promotion and salary increase has also been realized. Erik was surprised that why AAK hydraulic pilot operated pressure control valve was normal after 1 year of use, while other manufacturers surrendered early? The core of this hydraulic pilot operated pressure control valve is material and heat treatment. AAK adopts 20CrNi2MoV high carburizing bearing steel imported from Germany, combined with carburizing pretreatment process, through secondary quenching + cryogenic treatment + low temperature tempering process, which is cooled to 650 ~ 700 ℃ and discharged after cooling to 450 ~ 500 ℃. The microhardness is 237 ~ 247 HV, and its wear resistance and contact fatigue performance are increased by more than 3 times. After heat treatment, the thermal stability and compressive strength of the material have long been far ahead. Most manufacturers may choose right materials, but they may not be able to do a good heat treatment. AAK hydraulic pilot operated pressure control valve, select and use good materials.

AAK hydraulic relief valve uses quenching process to ensure 0.3mm finishing

Logan has been a purchaser of a hydraulic company in the United States for several years, and the purchasing of hydraulic valves in China is also very smooth. But recently, a high-precision hydraulic relief valve order worth more than $30,000 wasted him a lot of time. The original hydraulic relief valve manufacturer made the samples twice, but was still not approved by the customer. His customer understood that the original manufacturer was unable to meet the requirement of 0.3mm finish size allowance, and asked him to change the hydraulic relief valve manufacturer to make samples for the third time. If the hydraulic relief valve sample for the third time still cannot be approved, the customer can only cancel the order. This order attracted the attention of his boss, who asked him to solve the problem and get the sample of hydraulic relief valve approved at one time within 20 days. Five days later, Logan consulted many hydraulic relief valve suppliers, and most manufacturers said that they could not meet the standard of 0.3mm finishing size allowance. Logan is a little worried. He looks for hydraulic relief valve manufacturers everywhere on the Internet. He left a message on our AAK website: how can we guarantee the finishing dimension allowance? All such messages are basically for difficult problems encountered in the purchase of hydraulic valves. After some communication, it is understood that the Logan was stuck on the sample approval process of the hydraulic relief valve order, and he has contacted many hydraulic relief valve manufacturers, but no solution has been obtained. I suggested Logan try our sample directly, and let the test data to speak for itself and this also saves time. Logan doesn't seem to have a choice but to expect that maybe AAK hydraulic relief valve can pass the test. A week later, AAK sent out 3 hydraulic relief valve samples. Logan did not dare to send the samples to the customer directly after receiving them, so he had to find a third party for testing before sending them to the customer. Without incident, the customer approved AAK hydraulic relief valve samples. His boss was also surprised that how a hydraulic relief valve manufacturer found by Logan this time can solve the problem so quickly at one time. The heat treatment process in the early stage is the first step of finishing the size allowance. Most hydraulic relief valve manufacturers adopt local quenching, so the heat treatment process of the workpiece is not easy to control and may be deformed. As early as 6 years ago, AAK adjusted local quenching to overall quenching. At the same time, vertical flow treatment must be required for the hoisting mode in the process of quenching and tempering, so as to minimize the influence of tissue stress and thermal stress on deformation during workpiece heat treatment, so as to meet the requirements of dimensional allowance for finishing. Logan cancelled the order with the original hydraulic relief valve manufacturer without hesitation and confirmed the order with AAK hydraulic valve in two rounds. Logan privately told us that his customers like the hydraulic relief valve manufacturers such as AAK very much. The customer pointed out that AAK should be as the priority supplier for future inquiry of hydraulic relief valves. His boss was also very satisfied with his ability to quickly solve problems this time, and put higher and higher expectations on him. AAK hydraulic relief valves, strictly controls the size allowance of finishing to ensure the accuracy of products.

Comparing 30 factories, Arthur chose AAK hydraulic threaded cartridge valve

This Monday, Arthur sent an email to purchase 1,600 hydraulic threaded cartridge valves at one time, which was a little unexpected. Arthur came from a hydraulic equipment manufacturing company in Italy. He met with us at the PTC exhibition in Shanghai 3 years ago. At that time, he communicated with us for about half an hour. Then there were several inquiries for hydraulic threaded cartridge valves and several trial orders for hydraulic threaded cartridge valves. Last October, he suddenly sent an email saying that he had a client in Ningbo who wanted to visit AAK hydraulic valve factory. We introduced in detail a series of production links from raw material inspection and warehousing to rough machining, finishing, process inspection, assembly of valve body and spool, testing, packaging, warehousing, marking and shipping of each part of hydraulic threaded cartridge valve. After the visit, Arthur's client said they were satisfied with the scale, equipment and management of AAK factory and left. I wondered if this was really Arthur's client. More than a month later after visiting the factory, Arthur said that his company has developed a new hydraulic equipment, which requires high-precision hydraulic threaded cartridge valve. AAK needs to quote and make samples for testing as before. AAK sent 16 samples of hydraulic threaded cartridge valves after 30 days. I still think that this one will be the same as that one year ago, no big waves. I didn't understand that I made the mistake of "I thought" until receiving the large order of 1,600 hydraulic threaded cartridge valves yesterday. Today, I learned by email that it was not his client who came to visit the factory last year, but his assistant who often stayed in China. Before the company developed this hydraulic equipment, his assistant ran to more than 30 hydraulic valve manufacturers in China, especially for this special hydraulic threaded cartridge valve. AAK hydraulic valve has its own advantages in equipment and extension of equipment and on-site detail management. In particular, the component testing room of AAK is constant temperature and humidity for 24 hours, which is very helpful for hydraulic threaded cartridge valves with high precision requirements. Because of the particularity of this hydraulic threaded cartridge valve, the accuracy inspection of each component should be completed in a specific environment. Some quality problems of the products of many hydraulic valve manufacturers are just due to the deviation of the test results caused by the instability of the test environment. In the view of many factories, this may be a small detail, but AAK has done extremely rigorous testing. His assistant has not found a second one in Ningbo who pays so much attention to detail. That's why Arthur chose AAK to produce this big order of hydraulic threaded cartridge valve. AAK hydraulic threaded cartridge valves, with much attention on details, high standard and high inspection. Welcome to try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-threaded-cartridge-valves- aak169

AAK Hydraulic Manifolds Live in Trust and Reliability

Last week, Marc and I talked about a processing detail of hydraulic manifolds. By the way, I asked him why did you choose AAK for your first hydraulic manifold supplier 4 years ago. He just sent me 1 word: trust.   These days, I wonder: What is the core of AAK hydraulic manifolds? Is the manufacturing quality good in China? It must be good. The problem is that your hydraulic manifold is of good quality. How can you make customers think it is really good, and really reliable? I think they finally decided to place order with AAK because they trusted me, so I feel that trust is the key to a deal for the grassroots and our small bosses of hydraulic manifolds.   AAK hydraulic manifold is not a brand. I don't have a brand. It is neither a marketing, I don't study marketing, so I think trust plays a role. Whether brand or marketing, we seem to be pulled away by these words. AAK hydraulic manifolds do business through the Internet. In the end, I feel that it is not marketing, nor brand, but trust.   I want to put trust and reliability first. On the Internet, I never think about brands or marketing. As long as you think about how customers can trust me, you should think in this direction. You should think about the things that can be seen, touched and landed. If you do this well, in fact, the marketing is successful and the brand is gradually emerging. With trust and reliability in mind, instead of brand and marketing, the final goal was to achieve the goal of brand and marketing. Finally, the performance rose, and AAK hydraulic manifolds have been walking in this way.   99% of industrial products have no loyalty and reputation. Have you ever seen anyone hype hydraulic manifolds? AAK business relies on: 1) The hard strength of hydraulic manifold manufacturing quality. 2) The ingenious strength of peripheral innovation. 3) The soft power of online trust. The efficiency brought by trust is the highest, and the influence brought by trust is the greatest. The bonus brought by trust is more high-quality customers. To achieve performance and profit, we can only rely on high-quality customers. There is no second way to go.   The reliability is better than all brands and marketing. The promotion of AAK hydraulic manifolds is to pay less trust tax, and the promotion of AAK hydraulic manifolds is to reap trust dividends.   As for being a person that others can trust, I would like to tell what I saw in a hydraulic manifold factory of my colleague in the same industry yesterday. His assistant knocked on the door and said that he was uncertain about a customer. The customer requested to talk to the boss directly. The colleague said to his assistant: Tell the customer that the boss is not in the office. I hastened to say that you should leave me alone. In fact, I'm not worried about the customer on the phone. I'm more worried about the assistant. The assistant is watching him and learning from him.   Why can't many employees trust their managers? Most of the time, it is not because of big things, but just because of these small things. The dishonest small things that often happen in daily life gradually weaken and erode the credit. Small things are very important. For example, if someone comes to see you, you can make an appointment again if it is inconvenient. You can't tell the assistant that the boss is in a meeting, but actually the boss is not in a meeting. Your employees will always look at such small things.   There is an old saying in China, which is called "like a fish in water". For fish, water exists naturally. The fishes are full of water around them, and they are completely immersed in the water, even without being aware of the existence of water. If water is dry or polluted, fish will realize that water is its most basic need. Without water, fish will die. In business, trust is an indispensable part of transactions, and we rely on it. If polluted or not, we will die.   Without trust, all transactions will fail. AAK Hydraulic manifolds never do such a silly thing. https://www.aakindustry.com/info-det , ail/hydraulic-manifolds-aak394

AAK hydraulic check valve, 20% expensive, with service life twice than peer

This morning, Robert sent an email asking about the production time of 1,200 hydraulic check valves, which surprised me a little, because in the past 2 years, he normally just placed small quantity trial orders of hydraulic check valves. Robert is a purchaser of John Finlay company in Australia. We met 2 years ago. A batch of hydraulic tamping machine equipment of their company began to receive complaints again and again from the previous year. After inspection, it was found that the hydraulic check valve in the equipment did not maintain pressure. Robert contacted the original hydraulic check valve manufacturer to find a solution. The manufacturer advised that the working pressure and working frequency of the hydraulic tamping machine may be too high, resulting in frequent collision between the ball valve and valve seat of the hydraulic check valve, affecting the sealing effect. The only solution is to replace the leaked hydraulic check valve. Although replacing the hydraulic check valve is a heavy workload, Robert has no choice but to accept. The trouble is that 6 months later, the same problem happened again. The customer was very unhappy. The boss asked Robert to find a new supplier of hydraulic check valve immediately. Robert suggested purchasing hydraulic check valves from AAK to replace those unqualified ones, because the durability test of AAK hydraulic check valves was the most lasting among all of the samples from different manufacturers at the beginning. At present, there is an equipment installed with AAK hydraulic check valve, which has been used for 1 year but without any abnormality. The boss thought that the price of AAK was more than 20% higher and unacceptable, and asked Robert to look for a new manufacturer of hydraulic check valves. In the process of continuous screening, Robert selected 5 hydraulic check valve manufacturers to try their samples. Basically, after half a year, these hydraulic check valve samples had similar problems one after another. Robert was at a loss. He once again suggested to the boss to purchase AAK hydraulic check valves. After comparing so many hydraulic check valve manufacturers, none of their samples can be used for more than 1 year under this working condition, but the equipment installed with AAK hydraulic check valve has been used for nearly 2 years, and there has been no failure to maintain pressure. If the hydraulic check valve needs to be replaced every 6 months, the after-sales cost is too high, which has far exceeded the 20% higher cost of the hydraulic check valves. More importantly, it brings the reputation of unstable equipment quality to users. After listening to Robert's analysis, the boss approved AAK as the preferred supplier of their company for hydraulic check valves. It took Robert 2 years to persuade his boss to place a large order with AAK. He knew that the durability of AAK hydraulic check valve was more than twice that of other suppliers, and the after-sales cost was also low. How can AAK hydraulic check valve be durable under high pressure and high frequency use? According to the working condition requirements and working frequency of their company's equipment, AAK uses silicon nitride (Si3N4) ceramic ball as the ball valve, which has twice the hardness than steel, lower thermal expansion coefficient than steel ball, good roundness and small friction coefficient. It can resist the corrosion of most chemicals and can still not be worn under the condition of high pressure and high frequency use. The vast majority of hydraulic check valves are steel balls. Because the price of silicon nitride (Si3N4) ceramic balls is more than several times higher than that of ordinary steel balls, it will not be considered for cost saving. However, AAK uses special materials for special needs in combination with working conditions and use frequency, especially what most hydraulic check valve manufacturers are unwilling to do, but AAK likes this challenge most. AAK hydraulic check valves, focused on meeting customer needs. You can also give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak167

Hydraulic Cartridge Pressure Control Valve Zero leakage under High Pressure

Tarasios is a purchaser from a Greek hydraulic equipment manufacturing company. He has been very smooth in purchasing. At the beginning of the year, their customer customized a hydraulic power unit, and Tarasios chose a supplier that had cooperated for 5 years to make samples for the hydraulic cartridge pressure control valves. The commissioning of the prototype was not smooth. When the load on the pressure reducing branch increased, the pressure at the working port of the hydraulic cartridge pressure control valve increased and there was oil leakage, which affected the pressure maintenance of the oil circuit. They planned to add an accumulator to maintain the pressure, but the customer cannot accept the additional cost. The boss asked Tarasios to purchase the hydraulic cartridge pressure control valve without leakage under high pressure, but the original manufacturer gave up. After seeking other hydraulic cartridge valve manufacturers, it was fruitless. The boss was urging and Tarasios was worried. Tarasios found the website of AAK hydraulic valves on Google, and noticed that AAK has solved problems for customers many times, perhaps he saw the hope and sent us an email to ask: Can AAK make the hydraulic cartridge pressure control valve without leakage under the high pressure? We asked Tarasios to provide the detailed drawings and the system schematic diagram. After analysis, AAK engineers determined that only the original hydraulic cartridge pressure control valve structure is optimized, it can meet the requirement of no leakage under high pressure. Although it cannot be guaranteed to be success for100%, it is 90% confident. After 50 days, AAK sent out 12 hydraulic cartridge pressure control valves. 3 months later, Tarasios sent an email saying that the customer was satisfied with the prototype and was ready to issue a regular order. Their engineers were also satisfied with the function of AAK hydraulic cartridge pressure control valves. When the pressure at the working port increased, there was no leakage. AAK optimized the hydraulic cartridge pressure control valve from 3 aspects, with 3 seals to ensure no leakage under high pressure. 1. The valve body of the hydraulic cartridge pressure control valve is provided with a valve chamber, the side wall of the valve chamber is provided with a liquid outlet, the upper end of the valve body is provided with a seal seat, the upper end of the valve spool passes through the seal seat and is opposed to the spring seat, the lower end of the valve spool is provided with a radially projecting boss, which forms a conical seal with the lower end of the valve body. 2. The valve cover is installed at the lower end of the valve body, and the lower end of the valve spool extends into the valve cover, so that the inner cavity of the valve cover is divided into a liquid inlet cavity and a return cavity. The side wall of the liquid inlet cavity is provided with a liquid inlet, and the side wall of the spring cavity is provided with a vent hole. The outer wall of the seal seat and the inner wall of the upper end of the valve body are sealed through a second seal ring. 3. The valve spool is provided with a throttling channel connecting the valve cavity and the reflux cavity. A throttle port is formed between the valve spool and the lower end of the valve body. The up and down movement of the valve spool controls the opening of the throttle port. The outer wall of the lower end of the valve spool and the side wall of the inner cavity of the valve cover are sealed by a third sealing ring. When the hydraulic cartridge pressure control valve is working, the pressure at the outlet exceeds the pressure set by the regulating spring, and the pressure at the outlet of the valve chamber increases to the point where the valve spool can move up and the throttle between the valve chamber and the inlet chamber is closed, without any leakage. AAK hydraulic cartridge pressure control valve, 3 seals, no leakage under high pressure, you can also try a small order! https://www.aakindustry.com/info-det , ail/pressure-control-valves-aak458

AAK hydraulic check valves added with thread Anaerobic adhesives, 0 leakage

Last Friday, we received 3 emails from Niki, they are all the order for a same hydraulic check valve, but only the ship to address is different. It is the first time for their company to place the orders of 1,500 hydraulic check valves at one time. Niki is a purchaser of a Dutch hydraulic equipment company. Last year, a boarding bridge equipment needed hydraulic check valves. At that time, he planned to purchase from old suppliers. Unexpectedly, after dozens of hydraulic check valves from the initial samples were installed on the boarding bridge and tested for less than a month, the boarding bridge will slowly decline automatically. The engineer judged that the hydraulic system did not maintain the pressure, and it is likely that some hydraulic check valves leaked. However, after disassembling and inspecting the hydraulic check valves, it was found that the matching clearance accuracy of the valve spool and valve sleeve was within the normal range, and there was no jamming. Niki contacted the hydraulic check valve manufacturer, and manufacturer also didn't know why the hydraulic check valve leaked, so they could only replace those leaking hydraulic check valves. Niki is a little worried that if the leakage source of the hydraulic check valve is not found and replaced blindly, there may be a bigger problem later. Niki was not satisfied with the old supplier and had to start looking for new manufacturers of hydraulic check valves again. AAK received message from Niki on our website: what are the reasons for the leakage of hydraulic check valves? I realized that there was a leak in the hydraulic check valves purchased by Niki, but he hasn't found the root cause. After receiving the drawings of hydraulic check valve and the working conditions of boarding bridge equipment provided by Niki, we still can't 100% determine what caused the leakage of hydraulic check valve. We suggest him send us one of the previously leaked hydraulic check valves for analysis. After dismantling, our engineer is 90% sure to understand the root cause of the leakage, but still need to try sample to make it 100% sure. Niki is also willing to allow AAK to make samples according to his hydraulic check valve drawing. One month later, we sent 12 samples of hydraulic check valves to Niki and told him that the leakage of the hydraulic check valves from original manufacturer should be caused by poor details in production. There will be a certain gap between the cap and the thread of the valve sleeve of the hydraulic check valve. How to seal this gap is not only the detail but also the key, especially for the equipment with high working conditions. AAK uses thread anaerobic adhesive, which can completely fill the gap, enhance the sealing or retention force of mechanical connection components, prevent thread loosening and leakage due to vibration between the cap and valve sleeve of hydraulic check valves, and protect the joint from corrosion. Few hydraulic valve manufacturers can operate in this detail of gap sealing. Niki learned about this analysis, and replied that among more than 20 hydraulic check valve manufacturers he contacted, only AAK analyzed the sealing details. He expected to test the function of AAK hydraulic check valve samples. The 3 consecutive emails for orders last Friday should be indicating that the samples of AAK hydraulic check valves have passed the test. Niki specifically stated in the email that the reason why he chose AAK was that every detail of AAK hydraulic check valves was perfect and there was no leakage, so he placed big orders. AAK hydraulic check valves, focused on every detail, you are warmly welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak166

AAK solved the leakage in hydraulic check valves in 2 months

Cuenca is a senior purchaser of AGRIA company in Spain. The boss is very satisfied with his purchasing work. Two years ago, AGRIA company developed a hydraulic equipment, and there were complaints after sales for more than half a year. The main problem was that the starting force of the hydraulic system would be insufficient, which was caused by the increase of internal leakage of the hydraulic check valves in the equipment. After Cuenca contacted the original hydraulic check valve manufacturer, the manufacturer said that some hydraulic check valves may have deviation during assembly, and he was willing to replace the hydraulic check valves with large leakage with new ones. Cuenca thought it was completely solved after replacement, but what surprised him was that less than a year after the new hydraulic check valve was replaced, the same problem occurred again. The boss was very disappointed with his purchase of hydraulic check valves this time. The manufacturer of the original hydraulic check valves still said that except for replacing the hydraulic check valves, there is no other way. Cuenca began to worry that if the same problem happened a third time, it would be too shameless. To be safe, he began to look for a new supplier of hydraulic check valves and began to test samples. At the same time, he also wanted to know why the hydraulic check valves produced by the original manufacturer leaked. In this way, Cuenca contacted AAK hydraulic valve. After several rounds of communication with Cuenca, we learned the story between him and the original manufacturer of hydraulic check valves, and suggested him to send us the hydraulic check valves with problem and provide us the drawings of hydraulic check valves at the same time. AAK engineer disassembled the hydraulic check valves of the original manufacturer and found that there were wear marks on the sealing line on the surface of the poppet valve. When the pressure oil reversely enters the hydraulic check valve, the cone cannot strictly seal the oil and cause leakage, and some oil flows out of the oil inlet. After receiving AAK's analysis, Cuenca asked us to make 4 samples of hydraulic check valves according to his drawings. Our engineers designed a new hydraulic check valve according to the service frequency and working conditions of the equipment, replacing the cone valve with the ball valve. The cone valve is prone to fatigue creep deformation and wear after working for a long time, resulting in a gap between the valve sleeve and the cone, resulting in leakage. The outer circle of the ball valve can contact the inner taper ring line, and the connecting hole can be closed to reduce the leakage caused by wear. Cuenca was surprised that AAK dared to take the initiative to modify the drawings of their hydraulic check valves, and expected to see the sample performance of AAK hydraulic check valves. Two months later, AAK sent samples of the newly designed hydraulic check valves. A year later, Cuenca said that the hydraulic equipment equipped with AAK hydraulic check valves had no complaints about startup. He was glad that the original hydraulic check valve manufacturer replaced it again and again, which could only guarantee the service for half a year, but AAK solved the problem one time. In only 2 months, AAK helped solve the problem of leakage in the hydraulic check valves that plagued Cuenca for nearly 2 years. Cuenca would rather give up the original supplier who has cooperated for many years than choose AAK hydraulic check valves. AAK hydraulic check valve, valve spool design is unique and different, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak165

AAK hydraulic cartridge valve accuracy benchmarking European factories

Andy is our old hydraulic valve customer in the United States. The hydraulic cartridge valves he purchased from AAK in previous years always has a standard of machining surface roughness around 0.8μm. In February last year, Andy sent an email to inform us that in the future, the machining surface accuracy of their hydraulic cartridge valves will be improved to within 0.3μm. AAK engineers believe that based on the current equipment system, it is very difficult to improve the machining surface accuracy of hydraulic cartridge valves to 0.3μm. It is also very difficult to find such a hydraulic cartridge valve manufacturer in Ningbo. I know that AAK has only two options, either give up the business of his hydraulic cartridge valves or accept his accuracy standard. This is the first time I have faced the choice of "standing in line" since I joined the hydraulic valve industry. The cooperation with Andy has always been trustworthy, pleasant and efficient. AAK doesn't want to give up such customers. After two rounds of communication internally, AAK technical team has not reached a consensus. I have to call my retired master and hope to hear his opinions. My master told me that this is a rare opportunity to catch up with and surpass the accuracy of international hydraulic cartridge valves. The roughness of the working surface under 0.3μm is rare in China, but some European hydraulic cartridge valve manufacturers have this strength. AAK must first start with the equipment, and then select the most experienced operators from the factory for special aircraft training, so as to have the opportunity to compete with those top European hydraulic cartridge valve manufacturers. American HARDINGE precision CNC lathe is worthy of a try. At present, none of the domestic hydraulic cartridge valve manufacturers have this equipment. After contacting the equipment manufacturer, AAK technical team took the hydraulic cartridge valves produced for Andy before to the equipment factory, and asked the engineer of the equipment manufacturer to go directly to the machine for proofing. A week later, we sent the hydraulic cartridge valve samples to Andy and asked them to test the accuracy parameters. Two weeks later, Andy informed that the previous hydraulic cartridge valve accuracy test was completed twice. This time, AAK hydraulic cartridge valve was tested 4 times, and the accuracy fully met the standard. At the same time, he told me that after receiving the accuracy improvement notice, the other 3 domestic hydraulic cartridge valve manufacturers directly gave up, and only AAK dared to test the sample and succeeded in one test. He was very surprised. The machine tool to be introduced by AAK has advantages in accuracy. The parameters of the machine tool: spindle speed up to 6000r/ min, spindle radial run out ≤ 0.0008mm, positioning accuracy (X/Z) ≤ 0.005mm/0.008mm, repeated positioning accuracy (X/Z) ≤ 0.003mm/0.005mm, and machining surface roughness Ra ≤ 0.3μm. Turning roundness ≤ 0.4μm. Turning cylindricity ≤ 0.1μm. The spindle is a spring collet to clamp the workpiece, with large clamping area and stable processing. It is equipped with FANUC21i-T numerical control system with high precision. Now this HARDINGE machine tool is almost the special equipment for the orders from Andy. The order volume that Andy awarded to AAK has also increased by nearly 60%. He said that AAK hydraulic cartridge valve has surpassed many European factories in terms of precision.\ AAK hydraulic cartridge valves, with precision surpassing that of Europe, you are welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-valves-aak164

Accuracy of AAK hydraulic valve block is 5% higher than that of HydraForce

AAK uses the DMG five axis machining center imported from Germany, which improves the stability and accuracy by 30%. Less than 5% of the hydraulic valve block manufacturers in the domestic industry are equipped with this set of equipment. After suffering losses elsewhere, an American customer went back to AAK after 45 days to place the order for hydraulic valve blocks. Last December, I received an inquiry from American customer Joshua about a hydraulic valve block. At that time, I was a little surprised to see the accuracy requirements of the hydraulic valve block. The accuracy was 5% higher than that of HydraForce series. This was not a small challenge, but I was still confident. The next day, I sent quotation to Joshua directly. Joshua then said that it was 12% higher compared with other hydraulic valve block manufacturers, he could not place an order with AAK. After 45 days, Joshua asked us whether the last quotation of hydraulic valve block was still valid. If the original price is maintained, he will place the order for the hydraulic valve block. For the sincerity of cooperation, Joshua also frankly told why he moved the hydraulic valve block order to AAK. The original hydraulic valve block manufacturer made samples for two times, and the parameters of each hydraulic valve block were not very stable. Some hydraulic valve block sample had very good accuracy, while others were very poor, which wasted 3 weeks of time. Joshua also checked with other manufacturers. All of them are not confident to achieve the accuracy that is 5% higher than that of HydraForce series. Another 2 weeks were wasted again. The customer was very angry that the order has been placed for 5 weeks, but the sample of the hydraulic valve block still could not be approved. Joshua felt that only AAK can make the sample successfully at one time. Even if it is 12% more expensive, it is acceptable. Aware of Joshua's dilemma, we specially spare a high-precision DMG five axis machining center lathe to arrange the proofing of this hydraulic valve block. A week later, AAK sent the hydraulic valve block samples. After 10 days, there was still no feedback from Joshua about the hydraulic valve block samples. We asked Joshua to know that he was also waiting nervously. Until Joshua's email last week, we know that his customer was very surprised that the accuracy of this hydraulic valve block sample not only exceeded 5% that of the HydraForce series, but the parameter stability of AAK hydraulic valve block was also more than 30% higher than that last time. Frankly, we were not surprised by this data, because more than one customer was surprised by the accuracy parameters of AAK hydraulic valve blocks. The reason why the accuracy of AAK hydraulic valve block exceeds 5% of HydraForce series is that it firstly benefits from the continuous updating of the equipment. When the vast majority of hydraulic valve block manufacturers update from CNC lathe to domestic Mazak machine tool, AAK introduces DMG five axis machining center produced in Germany. The domestic Mazak machine tools have weak rigidity, poor stability and low precision after long-term processing. The lathe of DMG five axis machining center is equipped with transverse sliding seat of stiffened cast iron column, which provides the machine with high precision and high rigidity. It adopts the latest numerical control technology DMGEROline ® control panel, 19" display and 3D software, and guarantee the maximum working speed, accuracy and reliability. AAK hydraulic valve block, high precision, advanced equipment, you can also have a try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak163

AAK hydraulic needle valve has extraordinary assembly technology

Dimon is a new buyer of a hydraulic equipment manufacturing company in the United States. In the second half of last year, he purchased 100 hydraulic needle valves from an old supplier. After receiving the goods, the hydraulic needle valves were installed on the equipment. A few months later, some users complained that the pressure supply of some equipment was insufficient. Their technicians judged that the radial jamming of the valve spool of the hydraulic needle valve resulted in no flow regulation, which would lead to the failure of the power unit. The hydraulic needle valves need to be replaced with new ones as soon as possible to eliminate user complaints. His boss is not very satisfied that problem happened on even such a small number purchasing of hydraulic needle valves. Dimon is confused why the hydraulic needle valve supplier who had cooperated for 2 years would have such quality problems. He sent some problematic hydraulic needle valves back to the factory. The manufacturer replied that the accuracy of these hydraulic needle valves met the standard, but a small deviation in the size of the valve spool was caused by the deviation of the assembler. At that time, several valves were assembled at the same time in the assembly workshop, and a few deviations were difficult to avoid. Dimon realized that even the original manufacturer replaced the hydraulic needle valves with new ones, it still can not solve the problem of the radial jamming of the valve spool for 100%. He was afraid that if there were more user complaints, could he keep his job during the probation period? Dimon decided to find a new supplier of hydraulic needle valves. He left a message on our website: Can you solve the problem of radial jamming of the valve spool of hydraulic needle valve? At first, it was hard to answer this question. After several rounds of communication, we learned the story of his purchase of these 100 hydraulic needle valves. After reviewing the working conditions and drawings of hydraulic needle valve from Dimon, as well as the pictures of hydraulic needle valves from the original supplier, AAK suggested him trying samples directly. 20 days later, AAK sent 10 samples of hydraulic needle valves made per his requirements. Two months later, Dimon sent an email to us saying that he selected 5 factories from more than 20 hydraulic needle valve manufacturers to make samples. Only the samples from AAK and another factory did not have the problem of radial jamming of valve spool during the test. Their engineers suggested that AAK should be selected to replace the 100 hydraulic needle valves with potential quality problems, because the parameters of AAK hydraulic needle valve are the most stable. The boss knew that he dared to develop new suppliers and solved the hidden quality problems, although the probation period is not over yet, Dimon was approved to become a regular in advance. He told us this story privately. To do this hydraulic needle valve well, it needs not only high-precision equipment, but also need to avoid personal assembly errors. AAK has technical workers with more than 10 years of operation and production experience, combined with advanced high-precision honing machines, CNC machine tools and other production equipment, as well as advanced three coordinate instrument, cylindricity instrument, profilometer and other testing equipment. The most important thing is that AAK has specially assigned personnel to control the assembly process of hydraulic needle valves, so as to avoid partial mixture wrong assembly caused by cross assembly by multiple people, especially in the assembly process of similar valve bodies. Many factories arrange cross assembly in order to save personnel and improve efficiency, resulting in wrong assembly of accessories. This assembly process of AAK hydraulic needle valves is unique in the industry. Maybe there is no second factory in Ningbo, the hometown of hydraulic valves to do this like us. AAK hydraulic needle valves, no radial jamming of valve spool problem, welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak162

The 2022 Annual Report of AAK Hydraulic Valves

The gap between grass roots is not cognition, but the skill of making money. The gap between the elite and the elite is not skills, but the perception of making money. I have always positioned myself as a grass root and have been in the hydraulic valve industry for 14 years. Now I don't need to worry about the production workshop and there is a team for technical innovation. I need to constantly learn network skills and improve the network salesperson of AAK hydraulic valves. Over the past a few years, I have achieved little and I am satisfied.   At present, in most online businesses, most salesmen hope to use a detail page to burn advertisements. Anyway, the money is the boss's, not his (her)'s. If there is no customer coming, the responsibility lies in the company, and it has nothing to do with him or her. There are not a few people who have this understanding and attitude, and they have reached a consensus. This is a lazy government in function. Lazy politics is one of the corporate cultures, which is hard to reverse. It seems that online marketing is the responsibility of advertising, and the boss is unlucky.   AAK hydraulic valve online business, is to do a lot of things online, will slowly have inquiries. Most of the time, even if you have done a lot of things, you must do the content right, which is what customers want to see and need to see. On the contrary, if the content is wrong, the effort will be wasted. Do it every day. You must do it every day. If you don't do it, you will get 100,000 why’s. Once started, there were only 3-5 questions left. There is only one reason for endless questions – you don’t do it.   AAK hydraulic valve is not directly oriented to the consumer market, but mostly oriented to enterprise customers. For a long time, AAK has been focusing on the production technology and process of hydraulic cartridge valves, benchmarking the global leader in the hydraulic industry. The invisible champion enterprises in Germany often inherit several generations, and do not pursue the road of diversified and rapid expansion, but instead dig deeply into a specific field, achieve "one finger wide, one kilometer deep", and accumulate deep technical reserves and stable market channels. This is the future of AAK hydraulic valves.   Today is the last day of 2022. I always feel that I can't say enough. I'm worried that there is no logic. I still use rules to summarize the year of AAK hydraulic valves. This is also an annual report of AAK hydraulic valves to everyone who is following AAK. 1. 326 - 326 tweets have been published annually on the AAK hydraulic valve website. It is conservatively estimated to be more than 260,000 words.   2. 86 - AAK hydraulic valve tweets are published on 86 B2B platforms every day.   3. 341 - In AAK hydraulic valve or B2B, 341 messages have been received this year. As long as it is the right category, we will reply at the first time   4. 277 - We have received 277 inquiries this year, on average, there are inquiries every working day.   5. 142 - New and old customers, cumulative trying sample for 142 items.   6. 67 - In the program library of AAK hydraulic valves, 67 non-standard hydraulic valve customization programs have been added this year.   7. 46 - On the AAK hydraulic valve website, 46 new items were launched   8. 24 - In the customer list of AAK hydraulic valve, there are 24 new customers.   9. 6 - Among the new customers generated, are from 6 new countries.   10. 176 - AAK sent 176 packages this year.   11. 24 - 24 sets of hydraulic manifolds have been customized, and the average sampling time is twice a month.   12. 674 - In the AAK hydraulic valve program library, 674 sets of hydraulic valve standard parts have been accumulated, and the benchmarking is SUN, HYDRAFORCE, HAWE, REXROTH, international brands.   The year 2023 is coming, and there is no new idea. Just keep these 3 points: 1)Be optimistic about the future. Facts have proved that pessimists are absolutely right and optimists are sure to make money. 2)Never complain, just check your own problems. Facts have proved that the practice of muffling and continuous improvement is effective. 3)Go beyond the insistence of the surrounding people and do it every day.   Most people think that people who have been moving one step a day and accumulated continuously are clumsy and stupid. They think that there must be a shortcut to success. Unfortunately, they have taken the shortcut of life, but found it the farthest way. Someone laughed at me. Why does a person engaged in the production of hydraulic valves spend time every day on these tweets? In fact, just as Rolls Royce's advertising must be seen by the public, the public does not have the strength to buy Rolls Royce. However, if the public does not know Rolls Royce, people who drive Rolls Royce will feel that it is meaningless.   The black swan in 3 years may start to turn the page today, and do what you should do next year. I am a person who conforms to the current situation (time and situation). As long as interests do not conflict, I will not contradict what others say. Once people understand, they will become silent. It's not that you don't have the ability to get along with others, but that you don't have the interest to play tricks on the spot.   AAK hydraulic valves do not play tricks. One finger wide, one kilometer deep, I have been on the road. https://www.aakindustry.com/info-deta , il/hydraulic-cartridge-valves-aak457

AAK hydraulic valve block, pressure resistance over 450bar, no oil leakage

Connor is a purchaser from a Russian hydraulic company. There has never been oil leakage due to sealing in his previous purchases of hydraulic valve blocks. Some time ago, a rated pressure up to 450bar hydraulic valve block let him suffer due to the oil leakage of the hydraulic valve block. He communicated with the original manufacturer for many times and debugged for 3 times, but the oil leakage problem still cannot be solved. He then asked his other hydraulic valve block suppliers, they all suggested Connor giving up, because the current sealing technology cannot meet the pressure rating of 450bar hydraulic valve block. Connor also communicated with some new hydraulic valve block manufacturers online, and gradually understood the shortage of sealing technology. The 90% of hydraulic valve block manufacturers use the conventional sealing method of hexagon socket plug and sealing combination gasket, which is suitable for hydraulic valve blocks with rated pressure of 50-350bar only. For any over 350bar, this sealing method does not work and they have to give up. Can the sealing problem on a hydraulic valve block with 450bar rated pressure really not be solved? Connor still didn't give up. He found AAK hydraulic valve on B2B and came across an article about AAK hydraulic valve block using Swiss sealing technology to solve the oil leakage of hydraulic valve block. He left a message on our website: can you really solve the problem of oil leakage of hydraulic valve block with rated pressure above 450bar? Seeing this message, I realized that he should have been cheated by other manufacturers before, so he doesn't believe in the new hydraulic valve block manufacturers easily. We replied to him, no matter how much we said, maybe you don't believe it. Simply put, you directly order 1pc of hydraulic valve block according to your drawing. If the hydraulic valve block produced by AAK still leaks oil, we will directly refund you the fee of this testing order. Maybe Connor has no other choice or he sees hope, he agreed our suggestion. 14 days later, he received AAK hydraulic valve block. 2 days later, the test result came out. Their engineers deliberately pressurized it to 550bar, and no hidden danger of oil leakage was found in AAK hydraulic valve block. He wondered why AAK hydraulic valve block had no problem with even a rated pressure at 550bar? The reason that AAK hydraulic valve block can operate normally in the hydraulic system with the pressure of 550bar is because of the introduction of new sealing technology and MB Series Plug of KVT company in Switzerland. This plug mainly forms a solid sealing surface after intermetallic extrusion in the way of expansion and bite, so as to 100% avoid oil leakage of hydraulic valve block, fundamentally solve the problem of high-pressure sealing of hydraulic valve block. At the same time, it reduces pollution, so that the hydraulic valve block is more stable. This is also why Connor recognized the quality of AAK hydraulic valve block. AAK hydraulic valve block, superior sealing, zero leakage, you can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak161

AAK hydraulic valve block improved the design and successfully proofed

The hydraulic valve blocks designed and produced by AAK not only has high reliability and small pressure loss to ensure that there is no oil running between the channels, but also has compact structure, small occupied space, simple oil circuit and easy pipe layout, so as to ensure the high efficiency requirements of different actions of various actuator elements. The valve block can control the valve, which is easy to adjust and operate. AAK hydraulic valve block was designed and proofed successfully at one time within 1 month, which impressed the engineers of Samhydraulik company. The vast majority of hydraulic valve block manufacturers blindly proofed according to customer drawings, ignored working conditions, and did not understand the internal structure and working principle of hydraulic valve block. It is easy to cause hidden dangers in the hydraulic system, and the problem cannot be found. Justin left a message on AAK website (www.aakindustry.com) asking is the power insensitivity of the hydraulic system related to the hydraulic valve block? We replied that this is difficult to judge because it is a system problem that needs to be checked one by one. Justin emailed us the next day then we understood why he left such a message. Justin is from Samhydraulik in Italy. The power unit of a hydraulic system developed by his company needs a hydraulic valve block. Their engineers mentioned that the sensitivity of the power unit is the key and that all components need to cooperate closely. Justin thought that as long as the hydraulic valve block manufacturer strictly controlled the accuracy according to the drawings, it could be easily done. After the hydraulic valve block is finished, it is installed to test the hydraulic power unit. After the oil pump is started, the instantaneous pressure supply at the oil outlet of the power unit does not come up, and it just supply normal pressure after a few minutes. After checking each component one by one, it is suspected that there are hidden dangers in the hydraulic valve block. After detecting the hydraulic valve block, there is no problem in the oil passage and channel of the hydraulic valve block. Justin contacted the original hydraulic valve block manufacturer for analysis and solution. The manufacturer said that the hydraulic valve block was completely produced in accordance with the drawings of Samhydraulik company, and the accuracy was within the required range, and the reason for problem was unknown. Justin contacted several other hydraulic valve block manufacturers, they all said that they could match the drawings, but not sure about the problems of the hydraulic valve blocks. We asked Justin to tell us the working condition of the whole hydraulic system and the picture of the oil circuit running direction of the hydraulic valve blocks of the original manufacturer. AAK engineers have ideas after 3 aspects of comparative analysis. We told Justin that if your engineer determines that the problem lies in the hydraulic valve block, we will send you two samples of our hydraulic valve blocks to test your hydraulic system. Three days after receiving the samples, Justin informed that the instantaneous pressure supply at the oil outlet of the power unit was normal with AAK hydraulic valve blocks. Their engineers were surprised that AAK completed the design of the hydraulic valve block within 30 days and successfully proofed at one time. The problem of the hydraulic valve block lies in the high integration of the valve block design and the tortuous oil circuit, which will lead to high pressure loss and slow rise of system pressure. AAK engineers improved the design of the hydraulic valve block. The newly designed hydraulic valve block has no oil running between the channels, compact structure, small occupied space and optimized oil circuit piping, which not only has high reliability but also small pressure loss. AAK chief engineer has more than 20 years of technical experience. He is good at cross-sectional view, measurement and perspective of hydraulic valve block design system, multi angle observation of design process, hole connectivity, oil circuit optimization, and the escort of MDTools 3D solid design and virtual manufacturing software and high-precision CNC machining center imported from Switzerland. Many manufacturers do not know the problem of the hydraulic valve block. AAK can improve the design and make a successful proofing at one time within 30 days. I think this is the difference between AAK hydraulic valve block and its peers. AAK hydraulic valve block, not blindly based on drawings, but focused on the working principle, you are welcome to have a small try. https://www.aakindustry.com/info-detail/hy , draulic-valve-blocks-aak160

The only matching quality with German brand is AAK hydraulic valve block

Mathias, a Dutch hydraulic customer, urgently needed to purchase a batch of hydraulic valve blocks matching the German brand from China at the end of last year. He asked more than 10 old hydraulic valve block manufacturers. They all said that the accuracy of this hydraulic valve block was too high for their technology and equipment. Mathias had a hunch that nine times out of ten, the order for this hydraulic valve block would fail, because he knew that most hydraulic valve manufacturers just have CNC machine tools. But his boss attached great importance to this customer and asked him to implement the hydraulic valve block sample within 30 days. Within a week, Mathias consulted nearly 20 hydraulic valve block factories online and offline, almost all of them just have CNC lathes. Only two of them said that they have Japanese high- precision CNC machine tools. They can try to make samples but are not 100% sure. Two weeks later, Mathias tested the hydraulic valve block samples from 2 factories, and there was still a parameter error of 10% - 13%. Mathias suggested the factory re-make samples, and both factories surrendered. Time has been wasted for 3 weeks. It's only 2 weeks from the deadline required by the boss. Mathias is anxious and has no direction. While chatting with old friend Andy, Mathias revealed his dilemma. Andy is a veteran in the hydraulic valve industry and has cooperated with AAK hydraulic valve for 5 consecutive years. Andy told Mathias that the accuracy of this hydraulic valve block requires not only high-precision machine tools, but also old operators who understand the equipment. Most hydraulic valve block manufacturers are difficult to meet these two requirements at the same time. He suggested Mathias try AAK, who likes to overtime difficulties on high-precision hydraulic valves, and most operators have more than 5 years of experience in operating imported equipment. The subject of Mathias's first email to AAK hydraulic valve was that I was introduced by Andy. He said that the accuracy of this hydraulic valve block can only be produced in AAK. Opening his hydraulic valve block drawing, AAK engineers have 90% confidence. I replied to him directly that if it goes well, we can send the hydraulic valve block samples before the Chinese New Year holiday. Jan 28th is our last working day before CNY and the last day to send samples. Our team was great to send the samples on Jan 28th. When we came back from the Spring Festival holiday, we received an email from Mathias. Their technical team tested the accuracy of AAK hydraulic valve blocks. Each parameter met the accuracy required by the drawing, and almost every parameter was 30% higher than that of other hydraulic valve manufacturers. AAK is also the only hydraulic valve block manufacturer that can match the German brand among all the hydraulic valve manufacturers he contacted. He can finally make a report to his boss. Next, the order confirmation process of hydraulic valve blocks is very smooth. Mathias understood why Andy is optimistic that AAK can achieve the accuracy of this hydraulic valve block. AAK introduced Demage five axis machining center as early as 2 years ago. The allowable rotation range is 115 ° (- 5 ° / + 110 °), which can carry out negative angle machining up to 20 ° and high- precision machining, which can not be achieved by many imported machine tools. At the same time, the torque can reach 1800Nm, the Y-axis stroke can be increased from 1250 to 1600mm, and the maximum speed of milling spindle can reach 8000r/min, while the maximum of conventional CNC can only reach about 5000r/min. As long as the operator is familiar with the performance of the equipment, the hydraulic valve block similar complicated to that of Mathias is successfully proofed at one time. AAK hydraulic valve block is praised by Mathias that it is the only one that can match the German brand. Give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak156
