AAK unique 5 steps sand cleaning method replaces the traditional method commonly used by peers, and completely solves the problem of valve stuck or filter blockage of hydraulic relief valves caused by hidden danger in sand cleaning. The American customer placed an order for the hydraulic relief valves to AAK 3 days after the test run. Most of the bodies of the hydraulic relief valves are made of nodular iron, vermicular iron and gray iron and cast by sand turning with resin sand as the modeling medium. Therefore, there is sticky sand in the casting, which is easy to cause valve jamming and filter blockage. Most of the common sand cleaning methods of hydraulic relief valves in the same industry are shot blasting and electrochemical sand cleaning. These methods have limitations and are not conducive to the stability of hydraulic relief valves. Gabriel is a purchaser of a hydraulic company in the United States. In previous years, he purchased the hydraulic relief valves in the United States. Recently, there is an order for hydraulic relief valves. The production of the original domestic manufacturer is full schedule, while the other hydraulic relief valve manufacturers dislike the small quantity and are unwilling to accept the order. The company asked him to check with Chinese hydraulic relief valve manufacturers. Among several hydraulic relief valve manufacturers recommended by his colleagues, Gabriel chose 3 of them to send samples after a round of comparison. After 20 days, the samples of these 3 hydraulic relief valve manufacturers were generally stable and prone to valve jamming or filter blockage. The root cause was the incomplete sand cleaning process of the hydraulic relief valves. When browsing B2B websites, Gabriel saw that AAK website www.aakindustry.com introduced the 5 steps sand cleaning method of hydraulic relief valves. He left a message on our website: Can AAK make the hydraulic relief valves not stuck or the filter not blocked? We replied him directly: AAK hydraulic relief valves with 5 steps sand cleaning method have been recognized by German customers. You are welcome to try the order. Gabriel subconsciously approved AAK hydraulic relief valves but was still some concerned because of no cooperation before, so he asked for samples to test first. According to the draft of hydraulic relief valves sent by him, we sent samples in 2 weeks. Gabriel issued official PO on the 3rd day after receiving the hydraulic relief valve samples for commissioning, and requested that the bulk goods to be 100% sand cleaned thoroughly. AAK adopts more efficient sand cleaning method and has its own unique 5 steps sand cleaning method for small and complex castings, namely: Artificial aging - Pickling - Rinsing - Rust prevention - Ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting, so as to peel the sand off the casting, and then the explosion of compressed air during ultrasonic cleaning is used to make the sand fall off, so as to achieve the purpose of 100% sand cleaning. Gabriel issued the PO in 3 days after receiving AAK hydraulic relief valves for testing. This is a witness of AAK unique sand cleaning methods. AAK hydraulic relief valves do not block the valve or filter, which is due to AAK unique 5 steps sand cleaning method.

Nicholas is from an Italian hydraulic company. Last year, a batch of hydraulic equipment needed to use the hydraulic check valve urgently. Due to tight time, Nicholas purchased in Italy. After installing the local hydraulic check valve, the equipment commissioning was normal, but 3 months later, some users complained that the pressure of the power unit was insufficient. It was found that the hydraulic check valve was stuck on site, resulting in weak pressure supply of the system.    Nicholas contacted the original hydraulic check valve supplier and the supplier replied that the jamming was caused by unclean hydraulic oil. The on- site personnel found that the hydraulic oil was polluted, so they could only disassemble and clean the stuck hydraulic check valve. After replacing the hydraulic oil of the whole system, the equipment returned to normal. But a few months later, the same problem happened again, and Nicholas's after-sales personnel operated again as last time. The boss felt that the problem should be solved fundamentally after he knew it. Such after-sales cost is too high. Their engineers fed back that they could only install the filter screen at the inlet of the hydraulic check valve, but the original design of the equipment did not consider the position of the filter screen. It will cost more to refit the whole set of equipment.   The boss asked Nicholas to contact more local hydraulic check valve manufacturers to brainstorm. After knowing the problem with this hydraulic check valve from Nicholas, and the hydraulic oil is inevitably polluted, combining with their equipment working conditions and installation drawings, I told him that we can only find hydraulic check valve with filtering function. AAK has similar hydraulic check valve with automatic filtering function. Nicholas doesn't believe that AAK can provide such a hydraulic check valve. After receiving AAK sample and installing it, the equipment works normally. Nicholas asked us how long AAK hydraulic check valve with filter screen can work? We told him that there would be no users to apply for repair within 1 year.   Nicholas asked why we are so confident. I told him that a Canadian customer had the same problem last year. We developed this new hydraulic check valve. Within one year, Canadian customer has not reported that there is a problem with this hydraulic check valve yet. Half a year later, Nicholas sent an email saying that his customers had never changed the hydraulic oil after using AAK hydraulic check valves.   At that time, in order to save the installation space of filter plug-ins for the hydraulic system of Canadian customer, not to use bulky filter containers, and keep the system clean and extend the service life of hydraulic check valves, AAK designed a hydraulic check valve with filter embedded into the body, that is, the filter screen and the hydraulic check valve are installed in the valve block together. The filter made of 304 stainless steel can effectively remove the fine particles in the hydraulic oil, and it is no longer necessary to change the hydraulic oil once every 3 months.   AAK hydraulic check valve with filter screen saves money and worry.

Derya is from Türkiye. Most of the customers in Türkiye who contact AAK are dealers of hydraulic cartridge valves, but Derya operates a hydraulic equipment manufacturing company. At the beginning of this year, they developed an aviation hydraulic power unit that requires high-precision hydraulic cartridge directional control valves, especially the surface finish of the valve spool to be controlled within Ra0.3. Derya customized the hydraulic cartridge directional control valve with a manufacturer in China that had been cooperating for 3 years. 2 months later, the debugging of the aviation hydraulic power unit was not smooth, due to the insensitive opening and closing performance of the hydraulic cartridge directional control valve and equipment operation hysteresis. The engineer found that the surface finish of the hydraulic cartridge directional control valve spool from the original manufacturer exceeded Ra0.5. The original hydraulic cartridge valve manufacturer stated that they can only produce more valve spools and select them one by one. Derya realized that the manufacturing quality of the original hydraulic cartridge valve manufacturer was unstable, so he had to choose a new manufacturer for the hydraulic cartridge directional control valve. However, 2 months had passed since then, Derya was in a hurry. Derya found AAK on Google and left a message: 1. How long does it take for AAK to customize the hydraulic cartridge directional control valve? 2. Is it possible for AAK to control the smoothness of the valve spool of each hydraulic cartridge directional control valve within Ra0.3? After communication, it was learned that he was facing the dilemma of customizing a hydraulic cartridge directional control valve. I provided him a customer case of a hydraulic cartridge directional control valve previously customized for a Russian customer, with a surface finish of Ra0.2 on the valve spool and a video of how we handled the surface finish of the valve spool. Derya had no concerns anymore and requested AAK to make samples. After 50 days, AAK sent 20 samples of hydraulic cartridge directional control valves. 4 weeks later, Derya informed us via email that their aviation hydraulic power unit had been successfully tested and was on its way to deliver to the customer. The smoothness of the AAK hydraulic cartridge directional control valve spool was controlled at Ra0.2 and satisfied their engineers. For AAK hydraulic cartridge directional control valve spool components, the first is to choose suitable materials. For this model, we use 20CrNi2MoV high permeability carbon bearing steel, which has wear-resistant performance and can better protect the smoothness of the valve spool. Then it is polished and precision processed, and AAK uses a Taiwan centerless grinder. The process setting for centerless grinding is done by AAK this way: Firstly, the surface error and feed speed of the grinding wheel are set, and the surface error value of the hydraulic cartridge directional control valve spool is set to within 2μm, the feed speed of the grinding wheel is set at 400mm/min. The relative vibration between the grinding wheel and the valve spool, as well as the contact stiffness between the valve spool, guide wheel components, and support plate, can be more smoothly controlled, ensuring that the surface finish of each hydraulic cartridge directional control valve spool can be controlled within Ra0.2 after processing. AAK hydraulic cartridge directional control valve, the spool smoothness controlled within Ra0.2, you can also give it a try!

A few days ago, Titan, an old customer from Türkiye, sent me 6 samples of hydraulic cartridge valves. According to his description, there were 3 batches of the valves purchased from the original hydraulic cartridge valve manufacturer, and 2 batches of valves had abnormal service life. Some hydraulic cartridge valves had a service life of more than 1 million times, while some hydraulic cartridge valves had only about 700,000 times. However, no problem could be found in the selection of materials or accuracy of hydraulic cartridge valves. The original manufacturer of the hydraulic cartridge valves is also uncertain about the root cause of the problem, which has made Titan very upset. There are various possible reasons for unstable service life, such as material selection, machining accuracy, internal structure of the valve, and accessories. According to our testing, the valve provided by the original hydraulic cartridge valve manufacturer is unstable due to the quality of the spring, which affects the service life of the hydraulic cartridge valve. Titan mentioned that the Korean piano steel wire material used by the original hydraulic cartridge valve manufacturer should have a service life of no less than 1 million times. Yes, it is the basic standard for high- quality hydraulic cartridge valves to use piano steel wire. However, there are details on where the spring is processed and how to test its service life. Most hydraulic cartridge valve manufacturers just purchase springs from processing plants and then assemble them directly. Once there is a quality problem in the spring factory, it also affects the hydraulic cartridge valve manufacturers. Hydraulic cartridge valve manufacturer AAK controls the quality of springs through material selection and testing, based on 3 details: 1.The selection of piano wire is inevitable. 2.The length of the spring must be measured using a caliper, with the unit focused in millimeters. 3.The service life of the spring is controlled by specialized equipment. As shown in the video, hydraulic cartridge valve manufacturer AAK requires each batch of springs to undergo durability fatigue testing using a spring life testing machine. After the spring is inserted into the fixture, select the working mode in the program first, and then set 1 million tests to set the amplitude and frequency of the spring. Adjust the distance between the upper and lower pressure plates according to the length of the spring. After starting the equipment, the reciprocating motion of the connecting rod drives the compression work of the spring. The time and frequency of spring operation can be tracked on the screen at any time. If the spring is less than 1 million times, the program will automatically remind. AAK hydraulic cartridge valve has a service life of over 1 million times, which is the most basic requirement. You can also give it a try!

Whenever there is a new sample of AAK hydraulic valves, I must put it on the desk for a few days. Take a look at the hydraulic check valve with the same attitude of appreciating works of art, and taste a cup of coffee. The work is so simple.   The parameters of AAK hydraulic check valves have surpassed most of the domestic hydraulic valve counterparts, and the appearance is also beyond what the 10-year-old hydraulic check valve manufacturers are able to keep pace with. AAK hydraulic valves have no quality complaints for 6 consecutive years. In 2019, AAK hydraulic check valves were used on aircraft by a Russian customer, which is a witness of good quality.   AAK hydraulic check valve, how good is it? See the visual comparison in the picture below. Only from the appearance, the hydraulic check valve produced by 10 years old factory has lost. Not to mention meeting the parameters of hydraulic check valve using in aircraft, they may not dare to think or do it. AAK hydraulic valves is an ODM manufacturer for international first-line hydraulic valve brands. It is difficult to find the third one in Ningbo, the hometown of hydraulic valves.

Caspar is from a hydraulic transmission equipment company in Canada. He has been in purchasing for 5 years, and it is very smooth. In the first half of this year, a batch of hydraulic transmission units they sold was complained by customers that they often had cavitation. The first judgment should be that the hydraulic cartridge pressure control valve in the hydraulic system is abnormal, but the engineer thought that the valve was from the SUN hydraulics and should not have problem. He subconsciously thought that the hydraulic pump that Caspar purchased from China had a leak. After the test, it was found that the pressure at the outlet of the pump was stable. After checking one by one, only hydraulic cartridge pressure control valves from SUN were not checked, but the valve parameters were normal. The engineer was puzzled. After communicating with each hydraulic component manufacturer of the equipment, Caspar came to the conclusion that this SUN hydraulic cartridge pressure control valve may not be suitable for this hydraulic transmission equipment. However, none of the manufacturers of hydraulic cartridge pressure control valves can solve the hidden danger of cavitation, so they can only turn to SUN for help. But SUN was not interested in customizing small quantities. Caspar was helpless and anxious. Caspar found AAK while browsing Google. According to our background trace, he stayed on AAK website for more than 30 minutes, and left a message: Is the cavitation of the equipment caused by the hydraulic cartridge pressure control valve in the system? This needs to be specifically analyzed, according to SUN standard part number, hydraulic schematic diagram, equipment technical parameters, and used scenarios, AAK engineer believed that the SUN hydraulic cartridge pressure control valve of this model does not meet the special requirements of the equipment. AAK can sample the hydraulic cartridge pressure control valve, and it is 90% sure to solve the cavitation complaint. After 45 days, 10 samples of hydraulic cartridge pressure control valves were sent out. Last week, Caspar emailed that there was no cavitation after AAK hydraulic cartridge pressure control valve was used. The customer was very satisfied, but still had to continue to observe for several months. I told Caspar that AAK hydraulic cartridge pressure control valve had eliminated the cavitation hazard of the equipment in terms of function. As long as AAK hydraulic cartridge pressure control valve is within the service life, cavitation will not occur. How did this hydraulic cartridge pressure control valve replace SUN standard parts in function? In AAK hydraulic cartridge pressure control valve, there are two valve spools, separated by a spring, which is fixed in between 2 valve cages. The set value of overflow pressure can be set by adjusting the valve cage. At the same time, there is a damper between the two valve spools, which can provide positive damping of the hydraulic system. The valve can limit any input pressure in the inlet pipeline, prevent impact or pressure fluctuation when the actuator changes direction or stops suddenly, and also allow oil to enter the low pressure pipeline to supplement the oil drainage or any discharged flow. Its two-way cross type function can deliver the discharged oil to other pipelines to ensure the actuator is refilled with oil and eliminate cavitation. AAK customized hydraulic cartridge pressure control valve has more functions than SUN, and you can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-pressure-control-valves- aak398

Some time ago, Sean, who had purchased hydraulic cartridge valves from AAK for 7 years, suggested me opening up a production line for hydraulic motors. Without thinking about it, I replied that I currently do not have this capability. AAK currently focuses only on hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds. Sean didn't quite understand, but he was willing to support AAK to develop hydraulic motors. My understanding is that specializing in a subject requires 10 years, which is 10,000 hours of deliberate practice. I'm not a talent, so I use 10,000 hours as a ladder for my progress. The production of hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds takes a lot of time. The network promotion and sales of hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds require not only time, but also skills. Especially, AAK's customers, 100% of whom are from the Internet, need to regularly write product manuals, and pay attention to the flow of the network. At present, there is a large flow of cognitive, philosophical, and chicken soup jokes on social media, indicating that people's psychological state is generally anxious. Tragic stories always have a lot of traffic. People like to see others living worse than themselves, and they have a sense of satisfaction and comfort inside. I'm not the worst, many people are much worse than me. Foolish stories always have a large flow, and people are immersed in the Dack effect. The more they see others being so foolish, the more confident they become. Doing e-commerce and self media really requires thinking with traffic, if it is small and almost meaningless. AAK hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds, adhere to doing so, and think with trust. Any order for hydraulic cartridge valves, hydraulic valve blocks, and hydraulic manifolds that requires quality is almost always a product of trust. Trust is the cornerstone of AAK. The instructions for hydraulic cartridge valves should be frequently written and sorted out. Reading and writing are two different things. Writing out is a process of sorting out. And every time I sort, there will be new discoveries, which will help me understand my own products and introduce them to customers. This morning, I used another method to sort out my 3 hydraulic cartridge valves benchmarking SUN. Suddenly, I found this new discovery: If I don't do it one day, I can't see the difference; 30 days without doing anything, just a little short; If you don't do it for a year, there's a big gap. The vast majority of people only stay in understanding and knowing, but as long as they do it, they don't understand or know. The vast majority of hydraulic cartridge valve manufacturers will not modify their instructions for 3-5 years once they have completed them. AAK hydraulic cartridge valves, do things that 90% of their peers are unwilling to do, resulting in a group of high-quality hydraulic cartridge valve customers. https://www.aakindustry.com/ , info-detail/cartridge-valve-manufacturer-aak542

The situation of the economic environment at home and abroad, the lack of market confidence, and the willingness of people to consume, is very low. In fact, the more at this time, the more we need to polish our product quality. As a hydraulic manifold manufacturer, AAK adheres to the principle of "quality is 1". With the leadership of "1", the following matters will be meaningful. Even if a zero is added, it will be 10 times more effective. We look at the quality of our hydraulic manifolds from 3 perspectives.   AAK hydraulic manifold is not a large enterprise. As a representative of small and medium-sized enterprises, AAK aims to target the top 500 global enterprises, global famous enterprises and listed companies to do hydraulic manifolds. Get a big order from a first-line brand, do things with a sense of integrity and mindfulness. With this manufacturing quality 1, following with marketing, sales, these 0's will be useful.   1. Manufacturing quality of hydraulic manifolds We won't talk about the quality of AAK's service first. The customer will have a say in whether the service is good or not. If the manufacturing quality of hydraulic manifold is good, I have the most say. What is related to the manufacturing quality of hydraulic manifolds? AAK thinks it from 5 aspects:   1) The first is related to raw materials. Can I use A+ steel to replace A materials used by peers? For each trial order of AAK hydraulic manifolds, we first consider the material options. To compare what materials are used for hydraulic manifolds of domestic peers, and what materials are used for hydraulic manifolds of international first-line brands? Can AAK use A+ steel to replace material A used by its peers?   2) It is related to the advanced level of technology. The quality of the yarn produced by the same batch of cotton from the same place of origin in different textile mills is different. Why? The process is different. It is the same for hydraulic manifolds, different manufacturers, even if they are all produced with the same materials and equipment, will distinguish between different processes and quality. AAK is good at simplifying the hydraulic manifold oil circuit, and uses targeted process matching to reduce energy consumption.   3) It is related with equipment. Hydraulic manifold equipment is produced in Switzerland, Germany, America, Taiwan and China. The equipment is different, and the manufacturing quality is also different. AAK pays attention to the accuracy of the equipment, and is good at grafting personalized fixtures to ensure efficiency and stability.   4) It is related to processing technology. For example, for the processing of some special valve holes, AAK abandoned the conventional processing technology and adopted customized processing.   5) It is related to quality Control. In the whole production line, from material selection to each process, there are standards and quality inspection.   The manufacturing quality of AAK hydraulic manifolds focus on these 5 points. The manufacturing quality of hydraulic manifolds lies in slow and solid efforts of intelligent people. There is no shortcut to this road. There is no safe haven. Without manufacturing quality 1 takes the lead in the front, all 0’s added later will eventually return to zero. Just like life, whether you can stand on the waves and whether you can hold on the bottom of the waves.   2. Parameter performance of hydraulic manifolds AAK hydraulic manifold has stable performance, basically no failure, long service life and low energy consumption. These are the benefits AAK brings to customers.   The hydraulic cartridge valves are the core components of hydraulic manifolds, and AAK hydraulic cartridge valves are targeted at SUN, HydraForce and HAWE. We often dissect their new models, learn design, refine elements, analyze process, optimize technology, and gradually form a complete AAK hydraulic manifold system from the original design, processing drawings, material selection, material heat treatment, process sheet, processing technology, assembly, and testing. For Hydraulic manifold design, we have a complete process. From hole checking, wire network connection, hole network to component selection, oil circuit volume and assembly, all are linked to each other. AAK hydraulic manifold occupies less space, has less pressure loss, less leakage and less vibration. 3. The innovation of hydraulic manifold function In terms of personalized customization of hydraulic manifolds, it is not difficult to combine, vary and graft some hydraulic unit structures to create something new.   For example, the four-way AAK 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 component selection and adds the function of flow regeneration. This is technical work.   AAK hydraulic manifold oil circuit is designed into a network structure. The oil return is not only uniform, but also multi way oil return, which reduces the plugging holes in the oil circuit, simplifies the hydraulic manifold hole circuit, improves the oil flow capacity, and reduces energy consumption. AAK hydraulic manifold reduces pipeline connections and joints, reduces system complexity, and reduces energy consumption. It features compact structure, convenient installation, less maintenance, less leakage and small vibration.   AAK is Honeywell's hydraulic manifold supplier for 6 consecutive years. What are the advantages of purchasing hydraulic manifolds from AAK? In the words of Honeywell's purchasing director, it is 3 savings: time saving, cost saving and link saving.   1) Shorten the whole procurement process: plugs, connectors and manifold blocks can be produced in AAK. Procurement and tracking from multiple factories have become a one-stop process at AAK. 2) The installation process is simplified: AAK hydraulic units or manifolds can be directly installed into the equipment, and customers do not need to test the manifolds separately. 3) Undertake design services: from the hydraulic principle, oil circuit design, hydraulic cartridge valve selection, AAK can do 100% personalized customization.   AAK hydraulic manifold defines quality from 3 aspects. Focus on quality 1 and bring benefits to customers. https://www.aakindustry.com/info , -detail/hydraulic-manifolds-aak465

At the weekly meeting of hydraulic valve sales, I always ask our business team to study the production process of hydraulic valves with heart, observe the production of hydraulic valve at the workshop with heart, and think about customer emails with heart. Last month, someone asked me what is with heart? I was speechless for a moment. Recently, I saw an explanation in a book. The difference between using your heart and not is whether you are accepting the world as it is or observing how such a world will affect you? I think the explanation about the difference is in place and hit the nail on the head. Reading the email from hydraulic valve customer, word by word, and even forcibly reciting the whole email, which is still not called reading it carefully with heart. Reading with heart means thinking about these questions repeatedly in the process of reading: 1.What question is the customer asking or requesting about the hydraulic valves? 2.Do we have any problems with these hydraulic valves? If not, how to convince customers that we don't have these problems. 3.Is the answer we are going to provide persuasive? How can customers trust AAK hydraulic valves with the least amount of time? 4.These hydraulic valve problems raised by customers broaden my vision? If it is widened, what is the problem with my original frame about hydraulic valves? 5.Have I understood the customer's needs and emotions? If not, what's my problem? When you read the emails with these questions, you will find that we are not reading the emails, but observing our changes through external stimulation, and even receiving the customer's emotion. This is called reading the emails carefully with heart. AAK team works hard on the hydraulic valves with heart, and understands the needs of each customer with heart. This is our eternal direction! https://www.aakindustry.com/info , -detail/hydraulic-valves-aak197

This week, we’d like to introduce a Hydraulic Cartridge Counterbalance Valve equivalent to SUN standard part CBBA. Counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. In the year of 2022, a new customer from Turkey sent us inquiry for SUN model CBBA cartridge counterbalance Valve, 10 pcs for trial order and 100 pcs for annual order. After we quoted the price, we were advised that the competition in Turkey market is very fierce, AAK price is too high. That was not the first time that we received this type of feedback from Turkey customers, so we did not expect to receive any order from this customer. However, in September of 2022, the customer sent us inquiry for CBBA cartridge counterbalance Valve again. Feeling the real needs of this customer, AAK gave a 8% discount and the customer placed the trial order for 10 pcs of samples for testing. After that, we did not receive any further news from this customer. We thought that the customer may not approve the quality of AAK samples. Unexpectedly, 1 year later, in December, the last month of 2023, we received the regular order for 100 pcs of CBBA hydraulic cartridge counterbalance valve. Then we know that actually, AAK samples passed the testing, due to the earthquake in Turkey and some internal changes in the company, the customer’s buying plan was affected, so they held the order. AAK hydraulic cartridge counterbalance valve 2 advantages: 1. Function and Performance benchmarking SUN 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-CBBA 3:1 pilot ratio, restrictive counterbalance valve: Max. Operating Pressure: 280 bar (4000 psi) Flow: 20 L (5 gpm) Internal Leakage: 5 drops/min Temperature: - 30 to +120 °C (with Standard Buna N seals) Cavity: T-11A Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties Fluid Viscosity Range: 7.4 to 420 cSt AAK E-CBBA hydraulic cartridge Counterbalance Valve, equivalent to SUN CBBA, and the service life is 2 times of its domestic peers.

Recently, we launched a hydraulic cartridge pilot operated directional valve equivalent to HydraForce standard part PD10-41. It is a screw-in, cartridge style, pilot operated, spool-type hydraulic directional valve. Last April in 2022, a hydraulic cartridge valve customer in Russia found AAK when looking for a hydraulic cartridge valve manufacturer in China on google. After browsing AAK website, he had a very good impression about AAK, but because it is the first time for him to work with AAK, he was very cautious and just placed a test order of 10 pcs for a hydraulic cartridge pilot operated directional valve equivalent to HydraForce PD10-41. After 1 year of testing, it proves that the function and performance of AAK hydraulic cartridge pilot operated directional valve benchmarked the quality of HydraForce PD10-41. Today, we are very happy to receive their annual order of 1,000 pcs. AAK hydraulic cartridge pilot operated directional valve 2 advantages: 1. Internal leakage: 82ml/min, benchmarking HydraForce quality 2. Its service life is 2 times that of its peers Technical parameters of AAK E-PD10-41 Hydraulic Cartridge Pilot Operated Directional Valve: Max.

Lucas is from a Canadian hydraulic equipment company. He found AAK hydraulic valves online last September. His first inquiry was the hydraulic pilot- operated pressure control valve. After 3 rounds of email communication, he placed a trial order for 20 pcs of hydraulic pilot-operated pressure control valves. I received the order so smoothly, but I didn't expect that AAK would almost take the blame for others in the first cooperation. At the beginning of last month, Lucas informed by email that there were problems with all 20 hydraulic pilot-operated pressure control valves provided by AAK. When the equipment was installed and debugged, the hydraulic system went on strike. This is the first time I have encountered such a complaint. AAK will do various tests on each hydraulic pilot-operated pressure control valve before leaving the factory, and deliver it only after it is qualified. I asked the engineer and the workshop to verify. It was proved that the programming and production of the hydraulic pilot-operated pressure control valves are completely consistent with the drawings provided by Lucas, so I can ensure that the samples of AAK hydraulic pilot-operated pressure control valves are qualified. Our engineers speculate that there may be a problem with the oil circuit design of the valve block system, but Lucas engineers believe that AAK is shirking the responsibility. So I suggest Lucas try the hydraulic pilot-operated pressure control valves of other manufacturers to debug. If the hydraulic system is still abnormal, our guess is right. Two weeks later, Lucas frankly told us that there should be a problem with the oil circuit design and asked us what good methods we had? The next day, Lucas sent us the video of equipment commissioning. Indeed, during the operation of the equipment, the speed increases when the cylinder of the hydraulic system is lowered, which is equivalent to the increase of flow, and the original set pressure of the hydraulic pilot-operated pressure control valve will also increase, resulting in the instability of system pressure. Therefore, it is inferred that the instability of pressure is caused by the thin oil passage of the hydraulic valve block in the system. We suggest that he send us the schematic diagram of the hydraulic system. After analysis, AAK engineers believe that the oil circuit design cannot match the working conditions of the equipment. AAK plans to design and process a new hydraulic valve block, and then installs the AAK hydraulic pilot-operated pressure control valves to debug the equipment. If it is not successful, AAK will not charge any fee for the hydraulic valve block. A month later, AAK sent out the newly designed hydraulic valve block. Lucas sent an email 3 days after receiving AAK hydraulic valve block. He informed that after installing the AAK designed hydraulic valve block and the hydraulic pilot-operated pressure control valves, the hydraulic system was normal and the equipment operated smoothly. Their engineers also admire AAK professional analysis ability and problem-oriented ability to design and production. The failure of a hydraulic valve is not a point problem, but a system. Everything should start from the principle. The average working experience of AAK engineer team is 11 years. Among the hydraulic valve peers in Ningbo, it may not be possible to find the third hydraulic valve manufacturer as such. Lucas privately told us that his boss suggested that in the future, not only the hydraulic pilot-operated pressure control valves should be purchased from AAK, but also the hydraulic manifolds, because AAK specialty conquered his boss. AAK hydraulic pilot-operated pressure control valves, professional analysis, efficient design, maybe there is no 3rd manufacturer like us in Ningbo, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pilot-operated-pressure- control-va , lves-aak196
