Nearly 90% of the hydraulic cartridge valve manufacturers in Ningbo can not achieve the filtration accuracy as high as 10 Microns. But AAK is 1 of the less than 10% hydraulic cartridge valve manufacturers with a filtering accuracy up to 10 Microns. Dylan came to AAK HYDRAULIC VALVE with a very special two position two-way hydraulic cartridge valve. I knew he should have encountered a problem. For this special hydraulic cartridge valve, the filtration accuracy of 10 Microns was the minimum requirement. Dylan consulted the existing cooperated hydraulic cartridge valve manufacturers, but none of them could meet the requirement. Most hydraulic cartridge valve manufacturers said that the filtering accuracy of 25 Microns is 100% no problem. Only 1 hydraulic cartridge valve manufacturer gave feedback and was 70% sure that the filtering accuracy could reach 10 Microns. Dylan directly asked me, is it really difficult for these hydraulic cartridge valve manufacturers in Ningbo to achieve the filtering accuracy of 10 microns? How can so many hydraulic cartridge valve manufacturers have said that they can only achieve the filtering accuracy of 25 Microns? I could understand his helplessness and confusion. This is because that the conventional hydraulic cartridge valve manufacturers produce hydraulic valves according to domestic hydraulic standards in China. Not only 1 or 2, but nearly 90% of hydraulic cartridge valve manufacturers, can only able to get the filter element aperture reaches 25μm. We AAK HYDRAULIC VALVE also used conventional filters at the beginning, and the filtration accuracy was also based on domestic standards. 3 years ago, a German hydraulic valve customer requested the accuracy requirement of 10 Microns, which was not only a stimulus but also a challenge for us. After more than 2 months of adjusting, we improved the process on the small sample, and adjusted the equipment parameters until it was configured to a high-precision filter and cooperated with AAK special hydraulic oil, so that the filtration accuracy of particles in the hydraulic oil could be controlled to 10μm. 1 year later, some hydraulic cartridge valve manufacturers learned that AAK had upgraded with high-precision filters and followed suit. However, due to technical constraints, many hydraulic cartridge valve manufacturers still failed to meet the standard. Under the same working conditions, if the hydraulic cartridge valves from these hydraulic cartridge valve manufacturers have a service life of 2 years, the service life of AAK hydraulic cartridge valves can be extended to 3-4 years. Dylan was surprised that we had mass produced hydraulic cartridge valves with filtration accuracy up to 10 Microns 3 years ago, but only 1 of his current hydraulic cartridge valve manufacturers could do it, and with only 70% sure. Dylan took out the drawings and asked us to send samples of this special hydraulic cartridge valve within 20 days. AAK HYDRAULIC VALVE, always has high requirements on precision.

The hydraulic directional valves produced by AAK adopts its own proprietary quenching and tempering heat treatment process, which can greatly improve the strength of the hydraulic directional valve, avoid deformation and wear of the hydraulic directional valve in the long-term use process, and significantly increase the service life. Perhaps there is no second comparable manufacturer in Ningbo like this. At most, 10% of the domestic hydraulic valve peers can compete. In order to win orders, 50% of the hydraulic valve manufacturers do not do any heat treatment to the materials for the hydraulic parts. Although some hydraulic valve manufacturers insist on heat treatment, they can only be outsourced processing due to without equipment. There are also 20% of hydraulic valve manufacturers, who do not have a fixed outsourced processing place, so it is impossible to ensure the heat treatment quality, not to mention the stability. Due to these common problems in the hydraulic valve industry, the hydraulic valve will show many problems after being used for a period of time, such as product deformation and wear. Once the hydraulic valve is deformed, it will easily to be blocked and the service life of the hydraulic valve will be greatly shorten. 5 months ago, Mike, a hydraulic valve customer in the United States, came to me. He had been confused, since 2019, there have been continuous customer complaints about the hydraulic directional valve he purchased. All the complaints are that after the hydraulic directional valve has been used for a period of time, some hydraulic directional valves are deformed and some hydraulic directional valves are worn quickly. Obviously, there is a problem with the heat treatment of the materials used in the hydraulic directional valve. Since 2019, due to the environmental protection policy, the domestic heat treatment plants have been vigorously rectified, and there are much fewer processing places. 50% of the hydraulic valve manufacturers do not have a place to do heat treatment to the raw materials. Even if heat treatment is done, 20% of the hydraulic valve manufacturers have to change the processing places for each external processing. I sent him several samples of AAK hydraulic directional valve and told him that the material hardness of our hydraulic directional valve has not changed, which always can reach about 50-55HRC or higher, and there is no problem with the special requirement of 65HRC. He didn't know that the service life of hydraulic valve is our hard index. 3 months ago, Mike issued a test order for the hydraulic directional valve. Each different part of the hydraulic directional valve is marked with different hardness requirements. He also wants to know how AAK ensures the service life of the hydraulic directional valve. To get a long service life of hydraulic directional valve, heat treatment is the first and most critical step. In order to do a good job in heat treatment, AAK has held a heat treatment factory for 10 years. The quenching and tempering heat treatment of hydraulic valve materials is sensitive to temperature. If the temperature is too low, hardness is not enough and easy to deform. On the contrary, it will lead to cracking. Only our proprietary heat treatment process can accurately grasp the appropriate temperature under the operation of a master with more than 6 years of experience. AAK can also select the corresponding heat treatment process and determine the temperature range according to the different working conditions of the hydraulic valve to ensure the service life of the hydraulic valve. AAK hydraulic directional valve has a service life of more than 90% of its peers, you can also have a small try. https://www.aakindustry.com/

Uberto is from a hydraulic equipment company in Mexico and has been engaged in the procurement of hydraulic components for 2 years. At the end of last year, their customer customized a hydraulic power unit, and the hydraulic manifold of it was made by a local hydraulic manifold manufacturer. The commissioning of the equipment was smooth, and the customer was also satisfied, but the price of the equipment was more than 15% higher than that of similar products in the market. The company requested to optimize the hydraulic manifold to reduce the cost, but the original hydraulic manifold manufacturer has no idea. Uberto found AAK website on google. According to the background trace, he stayed for more than 10 minutes and left us a message: Can AAK optimize hydraulic manifold to reduce costs? After communication, we learned that the customer disliked the high price of their equipment. According to the schematic diagram of the hydraulic system provided by him and the original hydraulic manifold drawing, after discussion, AAK technical team proposed an optimization scheme, which is to form a combined hydraulic manifold, reduce the installation difficulty and cost. When Uberto's engineers learned that AAK had an optimized hydraulic manifold scheme, and that the cost would be reduced by 30%, they expressed doubts, then there was no further news. 2 weeks later, Uberto suddenly requested AAK to make samples for the hydraulic manifold and paid the development cost. After 50 days, AAK sent 3 hydraulic manifold samples. Last week, Ubertor emailed that the hydraulic power unit with AAK hydraulic manifold had been installed on the equipment and had been tracked for 4 weeks. The function and stability of the hydraulic power unit is the same as the original hydraulic manifold. Their customer decided to purchase their hydraulic power units. The boss was very satisfied and their engineers were also impressed. The combined hydraulic manifold optimized by AAK is a modular, configurable and open hydraulic manifold. It abandons the traditional mode of using "single element" combined circuit, avoids overlapping functions and structures, and reduces control valves, which is the key to significantly reduce costs. 1. The four-way hydraulic manifold control system is composed of pilot control valve group, 4 two-way cartridge valve control components, manifold blocks and connectors. It has 4 main channels, several pilot control channels, and 2 external mounting surfaces, which greatly reduces components. This is a technical activity. 2. The top of the hydraulic manifold is provided with a boss, which is a boss type step surface composed of the boss and 2 parallel finishing planes. The mounting surface of the convex part of the boss is installed with 2 groups of pilot control valve groups, and the mounting surface of the plane parallel to the boss plane is installed with a two-way cartridge valve. 3. The left and right sides of the hydraulic manifold are used to connect the high pressure input port and low pressure output port of the main channel as well as the pilot control channel, and the rear side is used as the connection port of the high pressure output port of the main channel. The installation of components is convenient and fast. AAK hydraulic manifold, focusing on cost performance, insisting on function and stability, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-manifolds-aak442

AAK HYDRAULIC VALVE has grown for 15 years, as one in the group of hydraulic valve suppliers in Ningbo. The supply of hydraulic valves has reached its peak and trough, but we always remember that we are a hydraulic valve supplier. I believe that as long as we don't give up and do hydraulic valves all our life, AAK will become the best hydraulic valve supplier. Our hydraulic valves have been supplied to 3 of the world's top 500 Enterprises. There may be no second such hydraulic valve factory among the Ningbo based hydraulic valve suppliers. Angelo, an American customer from top 500 enterprises, was introduced to AAK HYDRAULIC VALVE by a friend. He needed to make a sample of a hydraulic pressure valve for his customer to test new equipment. According to Angelo, he successively contacted no less than 10 hydraulic valve suppliers. After 2 rounds of elimination, 3 hydraulic valve suppliers were selected for proofing. The hydraulic pressure valve samples produced by 3 hydraulic valve suppliers had some leakage, vibration and noise under different working conditions. His customer was not satisfied with the samples from these hydraulic valve suppliers. The customer asked him to find an American hydraulic valve supplier. Considering the high cost of American hydraulic valve suppliers, he still wanted to try the hydraulic valve suppliers in China. If a qualified hydraulic valve supplier still couldn't be found, he had to give up. Due to equipment limitations, if the requirements of working conditions are relatively high, the hydraulic pressure valves produced by most China hydraulic valve suppliers will have the problems mentioned above. The fundamental reason is that the accuracy of hydraulic pressure valve is not enough. Generally, the ordinary hydraulic valve suppliers cannot do this high-precision hydraulic pressure valve. The accuracy of hydraulic pressure valve has always been a hard index of AAK. AAK is not only equipped with high-precision machine tools, but also with special equipment. AAK HYDRAULIC VALVE has many high-precision imported CNC lathes and honing machines, as well as many small AAK designed fixtures and assembled special processing equipment. Each equipment has operation instructions to eliminate human errors. For the coarse grinding in the early stage to the fine grinding in the later stage, at least 3 times of repeated debugging and testing shall be carried out until the accuracy index requirements are fully met. In Ningbo, it is difficult to find a second such hydraulic valve supplier. Angelo realized the difference between AAK HYDRAULIC VALVE and other hydraulic valve suppliers. A week later, we delivered the samples according to the product accuracy required by Angelo. His customers recognized the accuracy of the hydraulic pressure valve in 3 days after receiving the samples. Angelo was satisfied and said that AAK would be his preferred hydraulic valve supplier in Ningbo. AAK hydraulic valve has hard indicators and strict requirements. We aim to be the most trusted hydraulic valve supplier, or not to do. If you want to find a hydraulic valve supplier with high requirements, just contact AAK, www. aakindustry.com. https://www.aakindustr , y.com/info-detail/hydraulic-valve-supplier-aak101

A while ago, someone left a message on the website of hydraulic cartridge valve manufacturer AAK: How do you handle the fine burrs on the edges and corners of the hydraulic cartridge valve cage? This is a detailed issue that is often overlooked by most hydraulic cartridge valve manufacturers. Although his IP comes from Greece, I was not sure if he is a peer of hydraulic cartridge valve manufacturers or a purchaser. After two rounds of communication, it was learned that Apollo is an engineer from a hydraulic equipment company in Greece. They have been purchasing hydraulic components from hydraulic cartridge valve manufacturers in China for 3 years, and there are always some defects, such as residual burrs on the edges and corners of the hydraulic cartridge valve cage. They often have to manually handle these burrs, which has delayed their production progress and is very helpless. I was not in a hurry to tell Apollo, how hydraulic cartridge valve manufacturer AAK removes burrs and residues from the valve cage. Instead, I suggested that if he gives it a try from AAK, he may have changed his view on hydraulic cartridge valve manufacturers in China. Apollo seemed a bit hesitant, I can understand. A week later, Apollo sent an inquiry for a hydraulic cartridge valve that was equivalent to SUN standard part. After Apollo received AAK price, he did not give any comments, but just said: If I could learn how AAK can remove valve cage burrs, I would try the order first. I knew, Apollo still didn't trust AAK very much. Without trust, it is difficult to make a deal, which is the basic logic of business. I told Apollo that hydraulic cartridge valve manufacturers can basically avoid valve cage burrs as long as the precision machining is done in place. If there are indeed hidden problems, they can use the most traditional method of "friction". Apollo said that this mode is too time-consuming and not thorough, and he seemed to disagree. I sent him a video of AAK, a hydraulic cartridge valve manufacturer, on how to automate and remove valve cage burrs using the principle of friction. The next day, he confirmed the order and admired the wisdom of AAK engineers. In fact, this is very simple. In the earliest days, the removal of burrs on metal parts was done manually and slowly with sandpaper. Hydraulic cartridge valve manufacturer AAK designed an automatic deburring equipment based on this and combined with the working mode of cement mixers. Hydraulic cartridge valve manufacturer AAK does it this way: After the valve cage is finished with precision machining, 500 valve cages are placed into the equipment cylinder, and then filled with spherical abrasive particles. After starting the equipment, the valve cage continuously rotates in the abrasive particles, playing a role in polishing the edges and corners of the valve cage. The equipment uses a vibration motor as the excitation source. When the vibration motor rotates at high speed, the material in the cylinder moves in a circular motion in a horizontal plane, and the cylinder can spiral up, ensuring that each valve cage can friction 360 degrees without dead angles. Is it still necessary to worry about burrs when the valve cage has been moving in such equipment for more than 4 hours? 4 hours, 500 hydraulic cartridge valve cages, this efficiency is not low. AAK uses details to distinguish itself from hydraulic cartridge valve manufacturers in China, and you can also give it a try.

Engaging in the production of hydraulic cartridge valves requires not only energy, but also intelligence and pressure. To improve intelligence, reduce stress and restore energy, I think the best "medicine" is sleep.   If you sleep less than 6-7.5 hours a night, you will not be in good spirits, or you will be tired. When I was young, I got into the quilt and fell asleep immediately; When the alarm clock rings, I wake up and open my eyes. Every time I wake up, I have a feeling of resurrection. I can still sleep well these years, but sometimes the hydraulic cartridge valve work is not smooth, which will still disturb my sleep. After a period of exploration, I found a suitable 4 steps sleep method to adjust the pressure from the hydraulic cartridge valves.   1. Turn down the temperature of the bedroom. Low temperature helps us slip from shallow sleep to deep sleep. 2. 100% obscures the light source. The standard is to reach out and not see 5 fingers. What wakes me up can only be dreams. 3. Use exercise to consume the remaining power of the day. Exhausted, it helps to recharge quickly at night. 4. Keep early hours. Go to bed at 22:00 every night. Take a book to bed without reading your mobile phone. At 22:30, use this book to hypnotize yourself to sleep on time.   Compared with 10 years ago, my body weight has dropped by 27%. The root cause is diet and exercise. Although I wake up every day to face inquiries from different customers about hydraulic cartridge valves and messages on the website about hydraulic cartridge valves, my diet is almost fixed every day. I sum up as 2 meals and 2 waters.   1）After getting up: 500ml warm water. 2）Breakfast: 3 eggs (egg yolk removed), 300 ml milk shake (containing protein, dietary fiber, and some high-quality fat), and whole wheat bread. 3）Lunch: working set meal, containing vegetables, protein and cellulose. 4）Supper: 1 apple. 5）Not less than 1800 ml of water throughout the day.   Eating healthily is actually not an easy thing. It is necessary to fight against your eating habits for decades. However, I have tried to produce hydraulic cartridge valves for 14 years, which is not easy, so I think it's not a problem for you to adjust your diet.   What kind of movement does a hydraulic cartridge valve manufacturer who intends to work until the age of 95 need? Exercise is the means and health is the end. All human activities need energy. This energy is somewhat similar to the vehicle displacement. There may be no difference between 1.8-liter displacement cars and 6-liter displacement cars in urban areas. On the highway, the 1.8- liter displacement cars can only see the 6-liter displacement cars driving into the distance.   Next is sports. A fitness trainer with 17 years of experience has advocated the "one week fitness table", which is very helpful to me. Bobby jump, training core and heart and lung. Standard push ups, chest and shoulder training. Bow jump, training legs and heart and lung. Raise the horizontal bar, train the arms, shoulders and back. Every movement should be standardized and exhausted, 6-10 groups. One cycle a week.   How to prepare for the 50 years of AAK hydraulic cartridge valve? I do 3 things: sleep, diet and exercise.   2022 is a magic year. There are "guns" (conflict between Russia and Ukraine) and "germs" (COVID-19 epidemic). In 2023, focus on sleep, diet and exercise, and train yourself to be "steel". Guns, germs, and steel. I have already thought about it. I intend to work with my steel body for another 50 years. AAK hydraulic cartridge valve, with one heart, fight for a lifetime. https://www.aakindustry.com/info-detail/ca , rtridge-valve-manufacturers-aak515

The prejudice in people's hearts is a mountain, and many China manufacturers of integrated hydraulic cartridge valves have a deep understanding of this. Many people like to view the constantly improving integrated hydraulic cartridge valves made in China with a fixed perspective, even though they have multiple functions and high cost-effectiveness. Many people believe that integrated hydraulic cartridge valves in Europe and America are stronger than those produced in China. To be honest, in recent years, it has not been easy for China integrated hydraulic cartridge valve manufacturers to compete with foreign brands in terms of quality, while also suffering from bargain pressure from customers. In the field of industrial products, especially 10 years ago, customers had a natural trust and favor for integrated hydraulic cartridge valves produced in Europe, but they disdained China integrated hydraulic cartridge valves. In the 14 years of immersive exploration in the field of integrated hydraulic cartridge valves, AAK has also had a deep experience about this situation. In the first few years of doing foreign trade, there were many peers who looked down on AAK. At that time, some people always said that exporting to overseas markets. AAK could not achieve great success. We gritted our teeth through the winter of exporting integrated hydraulic cartridge valves, comprehensively upgraded our production workshop, introduced processing equipment and testing instruments from Switzerland and Japan, increased the procurement cost of materials by 20%, upgraded our production process, improved precision, and comprehensively improved manufacturing quality. Until the first Fortune 500 customer started purchasing integrated hydraulic cartridge valves from AAK, some peers became envious. Some people always liked to view the constantly improving AAK integrated hydraulic cartridge valves with a fixed perspective. This is unfair, but we cannot do anything about it. It seems that no matter how facts are used to prove, some people's prejudice mountain against the China integrated hydraulic cartridge valves is difficult to shake. Despite being looked down, AAK's confidence in integrated hydraulic cartridge valves has not been defeated. After 14 years of development, AAK is still alive and well. This is thanks to the support of our new and old customers, the industry giants HydraForce for 9 confidential years and Sun hydraulic for 5 confidential years. They are also listed companies in some countries, such as Skyjack Inc., or some military enterprises, such as B.L. Advanced Ground Support Systems Ltd (BL). Yes, Fortune 500 companies, industry giants, listed companies, and high-quality military enterprises, these customers are the source of AAK confidence in integrated hydraulic cartridge valves. There were Indian customers who used to compare AAK's integrated hydraulic cartridge valves with those produced in Germany at a price six times that of AAK, proving that AAK is "not good" This is just like spending money on high- speed rail but hoping to have the speed of an airplane, which is not in line with the market rules of integrated hydraulic cartridge valves. In the 14 years since the development of AAK integrated hydraulic cartridge valves, from the prejudice of "China domestic integrated hydraulic cartridge valves are difficult to go to overseas", to feel that AAK integrated hydraulic cartridge valves are good, and then the support and trust from established enterprises continue to purchase AAK integrated hydraulic cartridge valves, all of these is just like the flame of stars, are becoming more and more prosperous. Nowadays, there is an increasing number of people willing to speak fair for AAK integrated hydraulic cartridge valves, especially those in the same industry. We have been moved by this more than once. Nothing can repay enough, we can only integrate our passion into the never-ending research on integrated hydraulic cartridge valves, bringing customers more stable manufacturing quality, more suitable functions, and more satisfactory performance of integrated hydraulic cartridge valves. In the future, AAK integrated hydraulic cartridge valves will take a more resolute step, with supporting customers and colleagues, and make valves enter various industries.

A tiny detail of the hydraulic check valve symbol direction is wrong, which put the hydraulic check valve manufacturer in a very difficult position, the factory is almost closed. There is a devil in the details. Whether you can grasp the devil of the hydraulic check valve symbol requires you to think every day, in addition to hydraulic check valve, hydraulic check valve, and still hydraulic check valve. When I opened the mailbox, I saw the e-mail of Adair who we had known for 3 years. There was a habit with Adair. He purchases only one type of hydraulic valves from each one hydraulic valve manufacturer. We AAK HYDRAULIC VALVE has been his supplier for the hydraulic pressure valves. After reading the email, it was actually a proofing request for a hydraulic check valve, not a hydraulic pressure valve. It was a little abnormal. I thought he sent the wrong email. I reminded him whether the e-mail was sent by mistake. He said bluntly that he would need 3 samples of the hydraulic check valve as soon as possible, according to the drawings in his email. Somehow, I always felt there was a problem somewhere, and I went to see the drawing of the hydraulic check valve. It is found that in the layout at the bottom of the drawing, the arrow direction on the hydraulic check valve symbol is reversed. For the hydraulic check valve symbol, the arrow direction is reversed, which is fatal. It seems that a designer is unlikely to make such a low-level mistake. When the technical team got the drawing and started proofing, they called me. The hydraulic check valve symbol on the drawing seemed wrong. I'm glad they can also find that there is an objection to the hydraulic check valve symbol. I asked what they think of the hydraulic check valve symbol. They suggested making two sets of samples, one according to the hydraulic check valve symbol on the customer's drawing, and the other is for the hydraulic check valve symbol we understand. When Adair received two sets of samples, he deliberately asked why they were two sets of samples. When we pointed out the details of the hydraulic check valve symbol, Adair began to tell me the devil's story of the hydraulic check valve symbol. 6 months ago, he sent his hydraulic valve manufacturer the drawing with this hydraulic check valve symbol, which was made by their chief designer overnight. The hydraulic valve manufacturer proofed according to this drawing. As a result, the hydraulic check valve sample was also approved at one time. The devil began to make trouble from this time. The 2,000 hydraulic check valves were produced and shipped to his customer. The customer is testing a new production line and needs to use these hydraulic check valves. After installation, there is a big problem in startup and commissioning. Because of the wrong direction, the medium returned, polluting the whole new production line, and directly causing a loss of more than 260,000 US dollars. The customer sent the loss list to his boss, who asked the hydraulic valve manufacturer to bear it. The hydraulic valve manufacturer quickly found out the reason, but did not dare to directly tell the boss that this is the problem that the hydraulic check valve symbol on your drawings is wrongly marked. If offended the designer, there will be even no opportunity to quote in the future. Now the hydraulic valve manufacturer is in a dilemma. Bear the loss, the number is large. Not to bear the loss, they only have this only customer, Adair’s company. Who would have thought that this hydraulic check valve symbol butterfly wings directly incited the loss of more than 260,000 US dollars across the Atlantic. When the devil comes out, it seems difficult to find a way to the best of both worlds. The only way is to keep the devil in a bottle. AAK knows that there is a devil when looking at the hydraulic check valve symbol. If there is any problem with the hydraulic check valve symbol, please contact AAK HYDRAULIC VALVE: www.aakindustry.com https://www.aakindustry , .com/info-detail/hydraulic-valve-manufacturer-aak9 , 5

In Google, enter the types of hydraulic valves, and you can get a series of information about the types of hydraulic valves. It looks like that each description about the types of hydraulic valves are all right. This makes Berge a very big headache. He transferred from the quality control department to the import department. He is a very studious buyer. Every time, when domestic hydraulic valve manufacturers in China receive his design drawings, they ask a lot of questions about the types of hydraulic valves. Berge asked me how to clearly understand the types of hydraulic valves expressed by hydraulic valve manufacturers and how AAK classifies the types of hydraulic valves. I gave him an example. If there are a pile of chairs there with various shapes and materials, how should we classify them? Firstly divide the same kind of materials together, and then classify them for the second time to put different shapes together. This simple dichotomy is also suitable for the types of hydraulic valves. What is a hydraulic valve? It is a hydraulic element used to control liquid pressure, flow and direction in hydraulic transmission. Let’s classify the types of hydraulic valves for the first step: A.The types of hydraulic valves are divided into 3 categories according to their functions: directional control valve (such as one-way valve, reversing valve etc.), pressure control valve (such as relief valve, sequence valve, pressure reducing valve etc.), flow control valve (such as throttle valve, speed regulating valve etc.). B.According to the operation, the types of hydraulic valves are divided into manual valve, motorized valve, electric valve, hydraulic valve etc.. C.According to the control, the types of hydraulic valves are divided into Control valve, Cartridge valve and sandwich plate valve. D.According to the installation, the types of hydraulic valves are divided into threaded connection valve, plate connection valve, integrated connection valve, Superposition valve and cartridge valve Then, let’s classify the types of hydraulic valves for the second step. From above A category, if according to the installation, you will get the sub- category of the types of hydraulic valves, for example, the threaded hydraulic pressure valve. Berge understood the dichotomy of the type of hydraulic valves immediately, especially dividing them by using chairs as example, which is very practical. As soon as you listen and compare, you will understand, and can well understand the various questions about the types of hydraulic valves from different hydraulic valve manufacturers. In this way, the types of hydraulic valves are summarized from different angles. Combined with the dichotomy of the types of hydraulic valves, the types of hydraulic cartridge valves are basically clear, and they are interconnected and integrated. AAK HYDRAULIC VALVE can express any complex question about hydraulic valve to you with "analogy". You can not only understand it, but also use it. AAK HYDRAULIC VALVE, describe the types of hydraulic valves in the most landing way. If you have any questions about cartridge valves, please leave a message on AAK website www.aakindustry.com. We are always at your service. If you have any difficulties about the hydraulic valve, contact AAK HYDRAULIC VALVE. In addition, AAK adopts its own proprietary quenching and tempering heat treatment process to ensure the service life of hydraulic valves.

Most of the technologies of AAK HYDRAULIC VALVE are in the TOP 1-6 among over 200 hydraulic valve manufacturers in Ningbo. We have supplied hydraulic valves to 3 global TOP 500 enterprises. There may be no 2nd Hydraulic valve manufacturer like AAK in Ningbo. Last night, I had nothing to do, so I remembered that I hadn't talked to Ron for several weeks. I asked him on WeChat first "Is it convenient to talk?". 5 minutes later, Ron called me. I asked Ron if there had been any problem with the AAK HYDRAULIC VALVE service in the past more than 1 month. If there was anything we hadn't done enough, please leave a message at any time. Ron said that he liked hydraulic valve manufacturer like AAK because it made him feel very safe. I asked him curiously why he said so. Ron said, “The standard for me to choose a hydraulic valve manufacturer is whether the hydraulic valve manufacturer can reassure me. Because we Americans think when the matter is handed over to the hydraulic valve manufacturer, it means that the matter is over. We just need to wait for the result. For example, I place an order to the hydraulic valve manufacturer, which means that the work of my order to the hydraulic valve manufacturer has been completed. I just wait for the goods receipt." Ron went on to say, "For hydraulic valve manufacturer like you AAK, report everything. I still remember the first order I placed with AAK 3 years ago. When the sample sending time was approaching, you reported to me when the sample would be sent. After the PPS of hydraulic valve was sent, you reported me when I could expect to receive the PPS of hydraulic valve. On another occasion, due to the environmental protection, the sending of samples had to be delayed. You also gave me a detailed report on what problems AAK HYDRAULIC VALVE encountered, the new solutions and new sample sending date. These all are my judgments on the details of hydraulic valve manufacturers as the buyer of hydraulic valves. In my mind, AAK is the most detailed hydraulic valve manufacturer." I asked about the quality of the hydraulic valves we recently shipped. Ron said that he was not too worried about the quality of AAK HYDRAULIC VALVE manufacturer. The 3 global TOP 500 enterprises recognize the quality of AAK hydraulic valves. As long as there is no human error in the production of AAK HYDRAULIC VALVE manufacturer, the quality will be guaranteed. After talking for more than half an hour, Ron gave me a good lesson. It's difficult to do business with Americans. But if you do the details well, it's not difficult. The sense of service, time and quality are very important. Ron finally said, "AAK moved me with the quality I didn't expect and retained me with the details. It took the least time to purchase hydraulic valves from AAK and get assured quality. Who doesn't like such a hydraulic valve manufacturer?" After the call, I also felt the pressure. If there were problems in the details in the future, it would certainly affect Ron's judgment on what kind of hydraulic valve manufacturer AAK is. Today, I once again stressed with the whole sales team that we should pick up details one by one. If there are any problems, report the customers in advance. AAK is an excellent representative of hydraulic valve manufacturers in Ningbo. Hydraulic valve manufacturers like AAK, you may not be able to find the 2nd one in Ningbo.

This week, we’d like to introduce a hydraulic solenoid cartridge valve equivalent to HydraForce SV10-42. It is a solenoid-operated, 4 port, 2 position, direct-acting spool type, screw in hydraulic cartridge valve. Last September in 2022, a customer in Brazil found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. He was happy to found that AAK has the hydraulic solenoid cartridge valve equivalent to HydraForce SV10-42. Before contacting AAK, he had checked with over 6 hydraulic cartridge valve manufacturers in Ningbo China, but none of them have any similar or equivalent model.

In Ningbo, the hometown of hydraulic valves, conservatively speaking, there are more than 100 hydraulic cartridge valve manufacturers. 4 years ago, we began to contact HydraForce. AAK HYDRALUC VALVE lasted 2 years, replaced hydraulic valve materials 3 times and proofed 4 times, becoming the first hydraulic cartridge valve manufacturer supplier of HydraForce valves among so many hydraulic cartridge valve manufacturers in Ningbo. 4 years ago, I received a call from President Li, who is the agent of HydraForce valves in China. He said that from the hydraulic cartridge valve manufacturers in Ningbo, he heard that AAK HYDRAULIC VALVE have invested a lot of equipment and constantly innovated technology, and has a good benchmark in Ningbo among hydraulic cartridge valve manufacturers and asked if we are not interested in becoming a supplier of HydraForce valves. Everyone wants to cooperate with top 500 enterprises in the world. While agreeing, I am also a little nervous. I am worried that if the quality of hydraulic valves does not meet the standard, we would make jokes among these hydraulic cartridge valve manufacturers in Ningbo. The first entry point between us and hydraforce valves is a hydraulic cartridge valve. The AAK HYDRAULIC VALVE technical team spent 33 days and sent the approval sample of the hydraulic cartridge valve. We soon got a reply from HydraForce valves. They asked us to re-make sample, listed us those parameters to be improved, and also gave us some encouragement. At present, AAK HYDRAULIC VALVE parameters are among the top 3 of the hydraulic cartridge valve manufacturers in Ningbo. Since AAK HYDAULIC VALVE can represent the manufacturer of hydraulic cartridge valve in Ningbo, we must continue to overcome difficulties until the sample of hydraulic cartridge valve is approved. We constantly tested imported materials, replaced imported machine tools with higher precision, designed different fixtures, and assembled special equipment required for proofing. The 4th hydraulic cartridge valve has finally been recognized by HydraForce valves, and has also been affirmed by hydraulic cartridge valve manufacturers in Ningbo. AAK HYDRAULIC VALVE, in 2 years, replaced hydraulic valve materials 3 times and proofed 4 times, became the first hydraulic cartridge valve supplier of HydraForce valves among so many hydraulic cartridge valve manufacturers in Ningbo. HydraForce valves, one of the world's top 500 enterprises, recognized that AAK HYDRAULIC VALVE is a high-quality hydraulic cartridge valve manufacturer.

Forrest, from Spain, has been engaged in the procurement of hydraulic components for 3 years. At the beginning of the year, their customer asked for a set of hydraulic power units for military equipment, which had high requirements for hydraulic cartridge pressure control valves. The spool cylindricity was less than 0.0015, the roundness was less than 0.001, and the clearance between the valve spool and the valve cage was within 1μm. Forrest selected a manufacturer of hydraulic cartridge pressure control valves that has cooperated for 5 years to make samples. 2 weeks later, the manufacturer gave up. He was unable to process the valve spool, which has low efficiency and high scrap rate. Forrest contacted more than 10 other hydraulic cartridge valve manufacturers. They either had no reply or were only 60% confident. At this time, Forrest was worried. Forrest found AAK website in B2B, noticed the article about valve spool processing, left a message of 3 questions, and attached the drawing of hydraulic cartridge pressure control valve to remind that the valve is used on military equipment. 1. Can AAK process the valve spool with cylindricity less than 0.0015 and roundness less than 0.001? 2. Can AAK customize the hydraulic cartridge pressure control valve with the clearance between valve spool and valve sage within 1μm? 3. What is the lead time and cost to customize this hydraulic cartridge pressure control valve? I told him that the spool required by the drawing is difficult to process, but AAK has produced similar spool. Forrest requested for samples. After 50 days, 12 samples of hydraulic cartridge pressure control valves were sent out. 2 months later, Forrest e-mailed us that the customer had approved their hydraulic power unit. Their engineers are very interested in AAK's production of hydraulic cartridge pressure control valves. How did AAK do to ensure the accuracy of the valve spool. AAK adopts TSCHUDIN high-precision CNC cylindrical grinder imported from Switzerland, which meets the high-precision requirements of valve spool. The machine tool control system can automatically measure and store the inner hole and taper of the valve spool, and automatically grind out the size and taper of the valve spool according to the data. Two measuring heads are equipped in the radial and axial direction, and the measurement repeatability accuracy is less than 0.1μm. Carry out real-time online measurement and feedback, and realize 100% grinding process control before, during and after grinding. The tailstock is hydraulically driven, which can be driven by the system to precisely adjust the taper of the valve spool, with a resolution of 0.1μm. At the same time, two online measuring heads of the outer circle shall be matched to ensure the precision after machining, and the valve spool cylindricity shall be less than 0.0015, the roundness shall be less than 0.001, and the clearance between the valve spool and the valve cage shall be within 1μm. AAK hydraulic cartridge pressure control valve, the clearance between valve spool and valve cage is within 1μm, you can also try a small order! https://www.aakindustry.com/info-det , ail/pressure-control-valves-aak441

Alcander is from Greece. At the beginning of this year, they developed a large volume hydraulic manifold that requires hydraulic valve blocks. Alcander made 5 samples from a local hydraulic valve block manufacturer, but there was leakage in the assembled hydraulic manifold. The main reason was the large deviation in the size accuracy of some holes on the hydraulic valve block. The original manufacturer shifted the blame, and it is normal for the pore size of the large volume hydraulic valve block to deviate slightly. Alcander was very helpless. His boss asked him to search for a new hydraulic valve block manufacturer who can produce the large volume hydraulic valve block with hole size within accuracy of ± 5μm. Alcander felt the dissatisfaction of his boss. After checking with other hydraulic valve block manufacturers for 3 days, none of them was able to ensure that the accuracy of the pore size of large volume hydraulic valve blocks can be controlled within ± 5μm. Alcander searched for "China hydraulic valve block manufacturers" on Google and found the AAK hydraulic valve block on the homepage. He emailed us to inquiry: Can the hole size accuracy of large volume hydraulic valve blocks be controlled within ± 5μm? After communication, it was learned that he encountered difficulties in purchasing hydraulic valve blocks in their domestic market. According to his hydraulic valve block drawing, this model has a large volume and a weight of over 2 tons. Although there are requirements for the accuracy of the hole size, AAK not only has unique skills in processing, but the key is that after the hydraulic valve block is processed, there is a large bridge type laser coordinate measuring instrument to detect the size of each hole in the hydraulic valve block. Alcander requested AAK to make 5 samples for the hydraulic valve blocks. After the production drawings were approved, AAK completed the samples 45 days later. Last week, Alcander informed us via email that he needs to order 100 hydraulic valve blocks. I am a bit surprised, this quantity is not small, after all, it is large volume hydraulic valve block over 2 tons, which also indicates that the hydraulic valve block of AAK sample has passed the testing. Alcander provided feedback that their engineers are satisfied with the AAK hydraulic valve blocks; especially the accuracy of the orifice has reached ± 3μm. The processing of AAK hydraulic valve block holes is meticulous, and today we will only share the details of inspection. After the machining of the hole size of this large hydraulic valve block, a large bridge laser coordinate measuring instrument was put into use. Adopting the principle of laser interferometry, the two-dimensional coordinates of the measured object surface are converted into three-dimensional coordinates through a laser interferometer. This not only has fast measurement speed, but also high measurement accuracy and no dead corners. Its XYZ axis measurement range can reach: 2.5m × 2.5m × 2.5m, three axis adopts natural high-precision granite guide rail, reducing the probability of error. The error value can be controlled within ± 3μm, which is the biggest advantage of this measuring instrument. In Ningbo, there are no more than 3 hydraulic valve block manufacturers who have the 2.5m laser coordinate measuring instruments. AAK hydraulic valve block, large volume, with accuracy within 3μm, welcome to give it a try!
