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

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

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

This year, China's foreign trade data is not impressive, and it seems that the export of hydraulic manifold manufacturers to overseas markets has also been affected. A while ago, colleagues from Ningbo hydraulic manifold manufacturers had a salon where they analyzed the reasons for the foreign trade situation and made attribution.   Hydraulic manifold manufacturer A said that the overall consumption environment is not good, and customer procurement demand has declined. Hydraulic manifold manufacturer B said that the price has not been recognized by the market and a more competitive price is needed. Hydraulic manifold manufacturer C said that the quality of the product is not recognized by customers and there is a need to improve the manufacturing quality of the hydraulic manifolds. In summary, either the price is high, the quality is poor, or the customer purchases less, so the export of hydraulic manifold manufacturers to overseas markets has also been affected. However, have you noticed that many times, what we summarize is not one attribution after another, but one hypothesis after another. To challenge all unverified assumptions and increase the overseas exports of hydraulic manifold manufacturers, we must first understand why business has declined. That is to say, correct attribution. Attribution is a truth that has been verified to be true, false, and logical. And assumption is a possibility based on past experience and probability. Only when hypotheses have been verified one by one can they become attributions. Directly attributing assumptions can result in fatal consequences. All unverified hypotheses should be challenged at least once.   Many times, our assumptions are wrong. And these sounds were originally not difficult to hear. It is because of excessive belief in assumptions that all attributions are isolated from the wall. If hydraulic manifold manufacturers spend more time getting close to customer engineers, perhaps they can find the correct attribution. This is also why hydraulic manifold manufacturer AAK prefers to do online business rather than traditional models, for which as long as the buyer is secured, while online business not only requires stable hydraulic manifold manufacturing quality, but also daily communication, trust building, and interaction with customer engineers. Only such a three-point triangle is stable.   Hydraulic manifold manufacturer AAK, focuses on 3 points and insists on doing online business.

This week, we launched a hydraulic cartridge logic element benchmark SUN DKFS- XHN. This hydraulic logic element is a normally closed, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the open position. Most of hydraulic cartridge valve manufacturers in Ningbo China do not have this model. One of our customers in Brazil checked with 5 hydraulic valve manufacturers in 2 months, but none of them have this logic element. He was very happily to finally find it at AAK. But for it is his first time to do business with AAK, he ordered only 5pcs first last June as the trial order. Today, we received his regular order of 1,000 pcs for this SUN model DKFS-XHN Normally closed, balanced poppet, pilot-to-open logic element. It is said that AAK E-DKFS-XHN has passed the testing in the past year, its quality, function and performance is equivalent to SUN DKFS-XHN. AAK hydraulic logic element 2 major advantages: 1. Manufacturing quality, function and performance benchmark SUN. 2. But the price is less than 70% of SUN.

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

Bauer is from Brazil and has purchased hydraulic cartridge valves from AAK 6 times. In the second half of last year, they developed a drilling equipment. The hydraulic pressure control cartridge valve used on the equipment was sampled from a local hydraulic cartridge valve manufacturer in Brazil. The equipment commissioning was not smooth, and the impact of the drilling rig during startup and shutdown is large, which is not acceptable to the customer. The root cause is the unstable unloading of the hydraulic pressure control cartridge valve after overloading. The original hydraulic pressure control cartridge valve manufacturer stated that it was manufactured according to the drawings and its accuracy reached the standard. Bauer was helpless. Bauer contacted me and emailed me asking if AAK can produce a hydraulic pressure control cartridge valve with stable unloading after overloading, especially during equipment startup and shutdown. After communication, I learned the dilemma that Bauer encountered with the original hydraulic cartridge valve manufacturer. After discussion, AAK engineers gave the solution to the hydraulic pressure control cartridge valve, and Bauer asked AAK to make samples. After 45 days, AAK sent 10 hydraulic pressure control cartridge valves. 1 month later, Bauer informed us by email that AAK hydraulic pressure control cartridge valve was installed on the drilling rig, with minimal impact during startup and shutdown. Their equipment prototype had been delivered to the customer, and he was confident that the customer would place a batch order. AAK hydraulic pressure control cartridge valve not only achieves stable unloading after overloading, but also reduces impact. These are 2 advantages compared with the Brazilian hydraulic cartridge valve manufacturer. AAK hydraulic pressure control cartridge valve can adjust the annular orifice, the first and second orifices to achieve buffering and smooth operation of the equipment under various working conditions. AAK optimized the hydraulic pressure control cartridge valve in the following ways: 1. The hydraulic pressure control cartridge valve sleeve is provided with an oil return port and an oil discharge port, and a valve seat with a through hole is fixed. The valve spool is covered with a spring, and there is an oil passage inside the valve spool. The lower end of the valve spool is a tapered end. 2. The upper end of the valve spool extends into the valve spool sleeve, which is housed in the adjusting seat with a screw plug inside and a lock nut outside. Threaded connections are used between the lock nut and the adjusting seat, between the adjusting seat and the valve sleeve, and between the screw plug and the adjusting seat. 3. The screw plug cooperates with the valve spool sleeve to form a second oil chamber. The valve spool sleeve has two throttle holes and an annular throttle hole. The valve spool cooperates with the valve spool sleeve to form a first oil chamber. The lower end of the valve spool has an outer circumferential surface and a column that matches the inner wall of the valve sleeve. AAK hydraulic pressure control cartridge valve has 2 advantages over Brazilian hydraulic cartridge valve manufacturer. You can also give it a try! https://www.aakindustry.com/info-detai , l/pressure-control-cartridge-valves- aak533

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

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.

A top 3 hydraulic manifold importer in the United States, has been purchasing from a hydraulic manifold manufacturer in Ningbo China for 3 years. I met their procurement director Steven 2 years ago, but he did not know me. Last October, I learned that Steven had come to Ningbo, and I wanted to get to know him and introduce hydraulic manifold manufacturer AAK to him. I waited in the lobby of the hotel for over 3 hours, and when I saw Steven returning, I politely greeted him and presented my business card. I also briefly introduced the hydraulic manifold manufacturer AAK, and Steven replied gentlemanly, "I have your business card, so you can go back early.". At this point, if I say goodbye, it's estimated that the business card of hydraulic manifold manufacturer AAK will be in the trash can. On the road of business, do people, from strangers to acquaintances, essentially make use of each other? When you are valuable in front of others, some things are easy to talk about. I answered this way at the time: Thank you Steven for giving me a few minutes. I will say goodbye soon, but you need to keep this business card because it is very valuable to you. Steven shook the business card and asked with a smile, "What value does it have for me? You can talk about it.” I told him that there are 3 values. I know you have been purchasing from that hydraulic manifold manufacturer in Ningbo China for 3 years, and this hydraulic manifold manufacturer is also good. From the selection of suppliers, it can be seen that you are professional, which is why I came to visit you. I don't say that hydraulic manifold manufacturer AAK is better than your supplier, but at least not worse than him. For you, if there are any issues with the original supplier, hydraulic manifold manufacturer AAK is your best alternative option, so the first value that hydraulic manifold manufacturer AAK brings to you is safety. In the hydraulic manifold industry, hydraulic manifold manufacturer AAK is synchronized with your supplier. If you only cooperate with this one company, then there is a lot of information in this industry, and perhaps you only know half of it. With hydraulic manifold manufacturer AAK as a supplement, you are basically familiar with the information in this industry. If your boss wants to ask, how do you think about the development of this industry and how to adjust your procurement ideas in the future, you can have more comprehensive information. So the second value brought by hydraulic manifold manufacturer AAK is information value. The third value, if your supplier knows that hydraulic manifold manufacturer AAK is contacting you and he is also a bit nervous, perhaps he will treat you better, so the third value brought by hydraulic manifold manufacturer AAK is chip value. Finally, I told Steven that I know it's a bit difficult to discuss cooperation with you now. I only have one small request. Once you have the opportunity, can you give hydraulic manifold manufacturer AAK a try to see our manufacturing quality and my abilities? Is this a small request acceptable to you? Steven looked at the business card of hydraulic manifold manufacturer AAK again and said, "Okay, I will keep this business card for now.". At the same time, he also gave me his business card. Yesterday, I received an inquiry from Steven for a hydraulic manifold, and I have been waiting for him for 14 months. After communication, it was learned that the original supplier stumbled on this hydraulic manifold, which put Steven in a very passive position. I know and believe that the opportunity has come for hydraulic manifold manufacturer AAK.

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
