Esmaeel is from Iran. He is an interesting friend. If he doesn't have an order, he won't come to me, unless when he was in trouble. In the second half of last year, Esmaeel asked me to customize a hydraulic flow control cartridge valve as soon as possible. After communication, we learned that the test of their hydraulic pile driver was not smooth and the response was very slow. Their engineer judged that the hydraulic flow control cartridge valve was not awesome, which was customized by a hydraulic cartridge valve manufacturer in India. The manufacturer said that the system flow was too large, resulting in the slow response of the hydraulic flow control cartridge valve. The engineer was not satisfied with the original manufacturer and asked to replace the supplier. I asked him why he didn't contact AAK to customize this hydraulic flow control cartridge valve at the beginning. Esmaeel explained that this Indian cartridge valve manufacturer was designated by his customer, because this factory has ready-made procedures, which greatly shortened the development time. According to his hydraulic system schematic diagram and the original hydraulic flow control cartridge valve drawing, after internal discussion, I told him that the functions of the hydraulic flow control cartridge valve from this Indian cartridge valve manufacturer are not suitable for their equipment and it must be innovated. If AAK plan works out smoothly, we can finish samples within 45 days. 2 weeks after sending the sample of hydraulic flow control cartridge valve, Esmaeel told me that the pile driver test was successful, and let me wait for his good news. Today, I received the PO for 160 hydraulic flow control cartridge valves, and can't wait to share the innovative functions of our hydraulic flow control cartridge valves with you. AAK hydraulic flow control cartridge valve can realize large flow connection and fast response, here is what we do. 1. The valve spool and sleeve of the hydraulic flow control cartridge valve are of three-section type. The outer wall of each section of the valve spool is processed with convex steps. The cross-sectional area of the inner cavity of the three-section valve sleeve increases in turn. The axial through-hole of the valve sleeve penetrates from the lower end to the upper end. Each section of valve sleeve is provided with a plurality of radial oil ports, which are connected with the oil passage cavity. 2. The valve spool is sleeved in the axial through-hole of the valve sleeve, and the valve spool guide is arranged in the guide cavity. The valve sleeve is located in the control cover plate, which has 3 oil passages. One end of the return spring is connected with the control cover plate, the other end is connected with the second spool, and the oil passage cavity is connected with the return spring cavity. 3. There are 3 seals in the guide sleeve of the valve spool, and there is no leakage in the cavity. The optimized hydraulic flow control cartridge valve has 2 function positions. The flow capacity of the first function position is less than the flow capacity of the second function position. The two-way pressure control is adopted, and the response speed is fast. The hydraulic flow control cartridge valve can be controlled with less pressure oil. The flow difference in the system does not affect the response of the hydraulic flow control cartridge valve.    AAK hydraulic flow control cartridge valve, even if the flow is large, the response speed is still fast, you can also try it! https://www.aakindustry.com/info-detail , /flow-control-cartridge-valves-aak509

Krischnan is from a hydraulic equipment manufacturing company in the United States. He has been engaged in hydraulic manifold procurement for only 1 year. In the second half of last year, they developed a hydraulic oil pump to promote for new. The hydraulic manifold used comes from the design of their engineers. They chose a hydraulic manifold manufacturer who has worked with them for 5 years to try samples. 2 months later, the commissioning was not smooth. After the equipment was started for a period of time, the pressure supply of the oil pump was unstable, resulting in high energy consumption of the equipment, which had no advantage over the peers. The boss asked that the problem be solved within 3 months. The engineer asked Krischnan to contact the original hydraulic manifold manufacturer to solve the problem, but the manufacturer only had production capacity and can not offer solution. Krischnan was worried that the technical department blamed the purchase for the abnormal test run and had to check with many hydraulic manifold manufacturers. 1 week later, only one hydraulic manifold manufacturer replied that the manifold might need to be redesigned, but he was not sure. Krischnan was worried about time being wasted day by day. When browsing Google, Krischnan found an article of AAK about hydraulic manifolds and asked by email: Can you improve the hydraulic manifold design and make samples according to the working conditions of the equipment? I felt that he may have encountered problems on making samples for hydraulic manifolds. After communication, I learned that there was also a problem with the hydraulic manifold design. According to his hydraulic manifold drawings, as well as the condition of equipment commissioning, I told him that AAK was 80% sure to redesign the hydraulic manifold and sample it. If successful, it can help reduce the energy consumption of the equipment by 20%. Krischnan was happy but also worried when he learned that, but he seemed to have no choice but to bet on AAK's success. After 50 days, 5 redesigned hydraulic manifold samples were delivered. 4 weeks after the hydraulic manifold was sent out, Krischnan told us that the test run was smooth, the pressure supply of the oil pump was stable, and the energy consumption also decreased by more than 20%. The entire technical team was very happy and sure that it would be recognized by the market soon. The improvement of this hydraulic manifold is the reverse thinking operation, from "why the pressure supply is unstable" to the oil circuit and oil hole. AAK did this way: composed of relief valve, hydraulic time-delay valve and check valve. The sparkle is that there are oil inlet, oil return and oil outlet holes in the valve body. Each oil hole is connected to two cartridge valves, and the control oil holes of the hydraulic time-delay valve and the relief valve are connected to the corresponding oil holes in the valve body. The setting of another cartridge valve can make the pump have the function of one-way oil supply. The whole hydraulic manifold structure is compact, reducing pipes, joints and pipe fittings, simplifying the installation project, and replacing pipes with oil holes, which is also helpful for energy consumption. A few days ago, Krischnan told me privately that AAK's design idea was admired by their engineers. Now, people in the technical team respect him more when they see him, and what he does is more and more interesting. AAK hydraulic manifold, reduces energy consumption by 20%, and you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak375

China is now the second largest economy in the world, but some people begin to worry that China can not keep the second place, because in recent years, some manufacturing industries have been moved to Southeast Asia, which will affect China's GDP. Normal anxiety and pessimism are understandable, but they are useless. The more uncertain it is, the more sincerity and integrity are needed. China's hydraulic valve manufacturers with lots of blue-collar technicians are unlikely to be replaced by hydraulic valve manufacturers in Southeast Asian countries even after another 30 years. We are optimistic that the future of Chinese hydraulic valve manufacturers depends on how many blue-collar operators you have.   A country's industrial index is endorsed by factories with technical content, which requires Chinese hydraulic valve manufacturers to introduce or cultivate more blue-collar technicians, which is the confidence of the future. The goal of AAK Hydraulic Valve is that every operator should have a unique skill. Yesterday's achievements are not the end, and AAK Hydraulic Valve will never stop. The vast majority of technical blue collar workers do not compromise on quality. Even if the cost is 2-3 times higher, they should choose the best solution. Even if it's 2-3 times more expensive, choose the best one. Because it is not good enough, I cannot do it and give it to consumers. From the perspective of products as works, do you still worry about inferior products from operators with such mentality? AAK Hydraulic Valve can never say let it go. Once the scheme is determined, the sample shall be taken out. How do you do it? The devil of products is always in the details. The details are all questions that need attention.   Sincerity and integrity, we should be full of enthusiasm first, so as to better face the future. Success is not necessarily more fortunate than others, but more failures than others. If you fail, go through it. At the same time, do self-examination on your own process, technology, quality, service, and make improvements.   Sincerity and integrity also need to love life. As long as you love life, your anxiety and weakness will heal. You will have passion to write tweets, take videos of hydraulic valves and promote products.   Sincerity and integrity, we need to treat our partners with heart, produce hydraulic valves with sincerity and integrity, and serve users with sincerity and integrity. Sincerely face work and life, and face the future.   To serve customers sincerely, first of all, we should try our best to keep the real state, because we need to establish a long-term relationship with each other. It is the same logic to communicate with customers as go on blind dates. What should be the status of blind date? To be clean, wash your hair, wear a nice dress, and paint a light makeup. Because your purpose is to establish a long-term relationship with the other party, and it is to get married. Then you should try to keep your true state. If the other party appreciates the true you, you can build a long-term trust. If you create a false personal setting for yourself, and the other party is moved by the false personal setting, you spend 1 year and 2 years to get to know each other deeply, and find that it is completely different from what you knew at the beginning. If you break up again, it will cost a lot. If you hurt the other party, you also hurt yourself. Therefore, in my opinion, the promotion of hydraulic valves does not require public persona, because sincerity is the best way to lead to trust.   Sincerity is the best way to trust. The inquiry sent to you by the customer is actually a pre-sale trust to establish a long-term trust relationship. If you need to sell hydraulic valves, build trust by meeting, drinking with each other, playing ball, etc., that means your sweat on the hydraulic valves is not enough. Now, online can continuously reach customers, continuously provide value, and slowly build trust. The other party thinks you are reliable, which means you have pre-sale trust. Then, based on the trust in you, he will review your products. There is a time lag between the time when customers get to know you and the time when they buy. The purpose of AAK Hydraulic Valve promotion is to find ways to shorten this time difference. How to shorten it? There is logic behind this, which is pre-sale trust. The premise of pre-sale trust is sincerity. Only sincerity can establish a long-term trust relationship. AAK Hydraulic Valve, build relationship with sincerity and integrity. https://www.aakindustry.com/info-detail/ch , inese-hydraulic-valve-manufacturers- aak374

Tancredo comes from Italy, and he is an old hand in purchasing hydraulic manifolds. There are few hydraulic manifolds in cooperation with AAK. In the middle of last year, the first batch of hydraulic power units sold by their company, were complained of insufficient pressure supply and shock vibration 6 months after sales. During after sales service, it was found that the hydraulic cartridge valve of the hydraulic manifold was stuck, and the diameter of the intersecting hole of the valve block of the hydraulic manifold has deviation. The hydraulic manifold manufacturer advised that the residual burrs led to stuck, which may not be a large proportion. The hydraulic cartridge valves can be replaced for free, but he did not give reply about the diameter deviation at all. This after-sales service of hydraulic manifold is time-consuming and expensive. Tancredo realized that it was wrong to switch to this hydraulic manifold manufacturer, and was severely criticized by his boss. Before ordering this hydraulic manifold, Tancredo contacted more than 10 hydraulic manifold manufacturers successively, and I also received his inquiry, but I was told that AAK hydraulic manifold had no advantage in price, so he gave the order to another manufacturer. After the customer complained, Tancredo came to me again and complained that the selected hydraulic manifold manufacturer was unreliable. I told him that for the production of hydraulic manifold, more attention needs to be paid to the details of manufacturing quality. The manufacturers who can produce hydraulic cartridge valves very well, may not be able to produce hydraulic manifolds well. Tancredo did not dare to try other hydraulic manifold manufacturers, and asked AAK to try 30 samples of the hydraulic manifold. 6 months later, he tried another 30 hydraulic manifolds. I understand Tancredo's operation. He is scared to fail again, and can not face his boss. Last week, Tancredo told us that their engineers approved both batches of hydraulic manifold samples of AAK. The equipment installed with AAK hydraulic manifolds has been used for almost a year, and have no complaints. Why AAK hydraulic manifold can achieve reliable functions and guaranteed performance? It lies in 3 details of manufacturing quality: 1. The processing of hydraulic manifold block can ensure that the parallelism of two corresponding surfaces is less than 0.03mm, and the non perpendicularity of two adjacent surfaces is less than 0.05mm. The intersected drilling holes are designed according to the oil flow direction, and do not follow the trend to avoid eddy current or shock vibration. 2. Strictly control the treatment, deburring, rust removal, deoxidized skin removal, and cleaning of sharp edges of the hydraulic manifolds. Do not use traditional manual work. 3. Hydraulic manifold inspection, involves pressure test, function test, and is 100% fully inspected. AAK hydraulic manifold, 3 details of manufacturing quality, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-manifolds-aak373

Every October is the peak period for overseas customer visits. Hydraulic manifold manufacturer AAK has received 5 batches of customers and 2 new hydraulic manifold customers. Isaac, an old friend of hydraulic manifold manufacturer AAK, comes from Russia and his name is closely related to our name AAK. He has been busy in Ningbo for 2 days this time. After discussing several new hydraulic manifold developments in the AAK conference room, Isaac took out a business card and asked me if I know about this hydraulic manifold manufacturer in Ningbo. He would like to take me to visit this factory. Their company's other team purchased 10 sets of SUN standard hydraulic manifolds from this hydraulic manifold manufacturer, and there were no major issues, but there was leakage in the plug that was integrated into the manifold.  From the business card, I don't know this hydraulic manifold manufacturer. It's a bit awkward to go to a factory in the same industry. Isaac seems to feel my concern. The idea he gave me was that after arriving at this hydraulic manifold manufacturer, if we knew each other, I would wait in the car. If we don't know each other, then I'll follow him. Due to Isaac's persistence, I can only drive him along. Isaac contacted the other party and made an appointment to arrive at this hydraulic manifold manufacturer after 2 hours. Fortunately, we didn't know each other after meeting. I gave Isaac a reminder that we didn't know each other, and Isaac asked me to follow him in. After looking at the workshop first, the factory is not big. This hydraulic manifold manufacturer only produces manifold blocks and reassembles purchased hydraulic cartridge valves and other hydraulic components into hydraulic manifolds. This type of hydraulic manifold manufacturer does not require high technical content. Isaac started discussing the leakage of the plug in the hydraulic manifolds with them, and the boss seemed very angry about why such a low-level error occurred. He called in 3 people to communicate face-to-face. From the perspective of the scene, I felt it like a dead cycle, no one was wrong. Alas! It's not easy for the boss of a hydraulic manifold manufacturer to encounter a prickly management team.  I don't speak, I'm only responsible for recording. The boss of the hydraulic manifold manufacturer questioned A, who was in charge of quality. A stood up and said, "Quality is produced." This statement has a killing effect and pushes the blame. The boss immediately asked B, who was in charge of production, but B said, "The quality of production is guaranteed by technology, and production is just an executor. I feel that this B is more piercing than A. The boss turned to C, who was in charge of the technical department and next to him. C seemed angry and said, "I have adjusted the program and handed it over to the production department. Quality supervision should be carried out in the later stage. Throughout the production process, no one has reported any issues. Now that the customer complains, they come to me. I won't take responsibility for this issue”. Isaac asked me what they were discussing, and I can only say that they seem to be looking for a reason. The meeting has finally come to an end, and the problem seems to have been resolved, but it also doesn't seem to have been resolved. What I want to say is that in the quality management of hydraulic manifold manufacturers, there should be processes and systems, especially a comprehensive quality system. Inspection is only a small part of the functions of the quality department. If there are quality problems with hydraulic manifolds in the production workshop, they should follow the process to deduce. The first step is to identify the fault phenomenon and summarize the information. The second step is to identify the cause of the fault and determine the responsibility (design, drawing, production, component, assembly). The third step is to sort out the original production quality management process, identify and supplement deficiencies in the quality management system process, and solidify it. On the way back, Isaac asked me what is my impression of this hydraulic manifold manufacturer. I'm not sure how many hydraulic manifold manufacturers like this are in Ningbo, the hometown of hydraulic valves in China. Upgrading to a hydraulic manifold manufacturer is not difficult for manufacturers who can produce hydraulic cartridge valves themselves. But hydraulic manifold manufacturers may not be able to produce hydraulic cartridge valves well. For the problems encountered by hydraulic manifold manufacturers, no one may be able to solve them, so hire someone who can solve them. However, this person can be very challenging, expensive, and even more difficult to manage. If someone is hired to handle the process, the participants will be linked to each other and if encounter problems, continuously optimizing the process. Use processes to solve problems and review potential quality problems. Hydraulic manifold manufacturer AAK in Ningbo China, do not choose prick, but the process.

To safeguard electrical equipment from transient overvoltages, power substations frequently employ metal-oxide varistor (MOV) surge arresters. MOVs are made to deflect excess current away from the device they are safeguarding in order to limit the voltage to a safe level. The Benefits of Using MOV Block Substation Arresters 1 High-performance protection: MOV substation arresters provide reliable protection against transient overvoltages caused by lightning and other power system disturbances. 2 Long-term reliability: MOV substation arresters feature a robust design that ensures a long service life, helping to reduce the need for frequent replacement. 3 Suitable for a wide range of applications: MOV substation arresters are designed to be suitable for use in both indoor and outdoor applications, making them versatile and cost-effective. 4 Low maintenance: MOV substation arresters require minimal maintenance, helping to reduce the cost of ownership. The Impact of Lightning on MOV Block Substation Arresters Lightning is one of the most common and destructive natural phenomena that can have a catastrophic effect on substations and their components. This is especially true for MOV (Metal-Oxide Varistor) substation arresters, which are designed to protect electrical equipment from the high voltages caused by lightning strikes. When lightning strikes a MOV arrester, it can cause a surge of current that can damage the arrester and other components in the substation. This can lead to power outages, equipment damage, and even fire. To mitigate the effects of lightning on MOV substation arresters, various strategies can be implemented. These strategies include the use of surge protective devices (SPDs) to limit the current and voltage surges caused by lightning and the installation of lightning rods to direct the lightning away from the substation. Additionally, MOV substation arresters can be designed with higher levels of insulation to protect against the high voltage of lightning strikes.

TGE developed D36 & D42 series glass coating MOV which be suitable for distribution arresters according to IEC60099-4 (2014) in 2018. Based on the proven technique of high-performance metal oxide varistor, a special new type of metal oxide varistor can be used in heavy-duty distribution arresters has been successfully developed recently by TGE for the purpose of optimization of the electrical and economic performance of the new MOV with a diameter of 36mm & 42mm, that signifies not only its electrical performance meets the requirements, but also it can be led to cost reduction of zov varistor by means of smaller arrester dimension. MOV Block for Distribution Arrester Advantages 1 Excellent performance in the high current test: TOV reached 1.25Ur and 1s was higher than the standard 1.2Ur and 0.1s. 2 Higher protection level: TOV reached 1.25Ur and 1s was higher than the standard 1.2Ur and 0.1s. 3 High performance in 8/20µs charge test: Ures change is within 3% and Ures change is within 1% after Qrs 0.4C charge test with 8/20µs waveshape for TGE D36. 4 High performance in short circuit test: TGE wound core for customer passed 16kA short circuit test. 5 Stable aging performance. 6 High energy absorption capability. How Does MOV Block for Distribution Arrester Work? First of all, the stability of the electrical parameters of MOV under continuous operating voltage. The artificial accelerated aging test proves that in the life cycle of the MOV, its power consumption shows a declining trend with time. This means that in the long-term operation of the MOV or arrester, the power consumption or heat generated by itself will not gradually increase, so the MOV or arrester is in a stable state. On the other hand, when the MOV or arrester is subjected to continuous operating voltage for a long time, the influence of the change in ambient temperature on the power consumption or resistive current of the MOV is also a factor that affects the operational stability of the MOV or arrester. Since the power consumption or resistive current of the zov mov has a positive temperature coefficient, anyway, as the temperature increases, the power consumption or resistive current will show an increasing trend. But in spite of this, the improvement of manufacturing technology can make the change of power consumption or resistive current with temperature as small as possible, which is conducive to the safe operation of the arrester. The figure shows that the aging characteristics of the D36& D42 series MOVs show that the power consumption increases monotonously as the application increases. The figure shows the change in power consumption of the MOV at different temperatures. Especially at a temperature of 190 ° C, the power consumption of the MOV sheet remains low. This is particularly important for the design of lightning arresters. When operating load or TOV test, the temperature rise of the MOV is very high due to the large energy absorbed by the MOV, and only when the high temperature power consumption remains low, it is Specification of special metal oxide varistor for heavy duty distribution arrester easier to reach the heat under the recovery voltage or MCOV voltage stable. After the surge arrester in operation absorbs overvoltage energy, due to the lower high-temperature power consumption of the MOV, the heat generation of the surge arrester is lower, which is more conducive to the safe operation of the surge arrester Secondly, the stability of the electrical parameters of the MOV sheet after being subjected to different pulse currents. The most obvious characteristic of the MOV after undergoing a large pulse current and absorbing the corresponding energy is that the temperature rise and the reference voltage leakage current or power consumption and residual voltage after cooling have a certain amplitude change from the value before the pulse current.

Fossette is from a navigation and aerospace equipment company in Canada, and has been purchasing for 4 years. At the beginning of the year, their customer wanted to customize a marine hydraulic power unit, which was very strict with the hydraulic cartridge directional control valve. He contacted HydraForce for customization. Because of small quantity and tight time, HydraForce could not meet the needs of Fossette. He selected hydraulic cartridge directional control valve manufacturer in Ningbo, who has cooperated for 2 years, to make samples. The manufacturer guaranteed that the geometric accuracy of the valve spool and valve cage is 0.8μm, but it was jammed during equipment commissioning. The hydraulic cartridge directional control valve of this manufacturer is inflexible, and the accuracy is 50% lower than the requirement. At this moment, the manufacturer said that 1.2μm of hydraulic cartridge directional control valve is the limit, and their engineers can't fulfill their promises. Fossette contacted more than 10 manufacturers of hydraulic cartridge directional control valves, but it was also fruitless. The time was wasted for 6 weeks, the customer was dissatisfied, and Fossette started to worry. Fossette saw on B2B that AAK has released a customer case about "0.8μm Accuracy of hydraulic directional control valve", he left a message on AAK Hydraulic Valve website, asking 3 questions consecutively: 1. Accuracy 0.8 μm Hydraulic cartridge directional control valve, are you SURE? 2. Customization time? 3. The quantity is small, are you interested? He specially emphasized “SURE” in capital letters. He may be feared of being disappointed again. I told him that the precision of 0.8μm Hydraulic cartridge directional control valve, is already an existing fact for AAK, it is not a matter of SURE or not. I need a complete drawing to evaluate the probability of customization success as a whole. 40 days later, AAK sent 10 customized hydraulic cartridge directional control valves. After that, there was no email from Fossette, and I did not follow it. Generally, the customer will give a feedback 2-4 weeks after receiving the samples. 4 months later, just last week, Fossette informed us that his customer was very satisfied with the marine hydraulic power unit they provided. He was preparing for the annual order and asked me to keep an eye on the production in the workshop to ensure the progress and manufacturing quality of large goods. The hydraulic cartridge directional control valve accuracy within 0.8μm, challenges the processing equipment, the technical team and the manufacturer's quality awareness. 1. In terms of finish machining, OKK ultra precision machine tool from Japan is used, and AAK self modified fixture is equipped, accuracy of 0.8μm is not our limit. 2. AAK engineer team, in terms of the selection of raw materials and spare parts, starts from the requirements of working conditions and is targeted, never following the trend. Especially in the customization of high-precision hydraulic valves, the processing of production drawings, the preparation of processing technology, the technical control, they have unique skills and successful cases. 3. In terms of inspection, dare not be careless. The German Mahr cylindricity meter is used, with the help of EasyForm software, and 100% full inspection is carried out. Only those qualified can go to the packaging workshop. AAK hydraulic cartridge directional control valve, used in navigation and aerospace, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-directional- control-valv , es-aak372

Today, AAK posted a Pilot-Operated, Pressure Reducing/Relieving Valve benchmarking SUN Hydraulics' PPFB series, and we have developed 3 sub categories: E-PPFB-LAN; E-PPFB-LDN; E-PPFB-LWN. The working characteristics of this pilot operated pressure reducing/relieving valve are: the pilot operated valves exhibit exceptionally flat pressure/flow characteristics are very stable and have low hysteresis. Pilot operated reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves. The function of this pilot operated pressure reducing/relieving valve is to reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3).

Coleman is from a hydraulic equipment company in Ecuador. He has been engaged in procurement for 3 years and has been quite smooth. In the second half of this year, the hydraulic winches they have sold out for 8 months was complained by customer that they were slipping under load and were prone to shake. After checking, it was found that the hydraulic cartridge counterbalance valve in the system was abnormal. The original manufacturer of the hydraulic cartridge counterbalance valve said that under such working conditions, the hydraulic counterbalance valves would need to be replaced every 8 months. The boss was not satisfied with this short service life and asked Coleman to find a hydraulic counterbalance valve manufacturer who can guarantee a longer service life. Coleman was surprised that all other hydraulic counterbalance valve manufacturers he contacted said that the original manufacturer was correct. Coleman saw AAK on Google and sent an email for inquiry with the attitude of trying. After communication, we learned his purchasing status. According to his hydraulic schematic diagram, working condition requirements, and hydraulic counterbalance valve drawings, AAK engineers also agreed with the opinions of the original manufacturer, but AAK has an optimization plan, and can guaranteed a service life of at least 16 months. When Coleman learned that AAK wanted to optimize the structure of the original hydraulic counterbalance valve, he hesitated and worried that it would affect the function, and his engineers may not accept it, so there was no news from him for a week. 7 days later, Coleman told us that he had no choice but to pay for the development cost by himself to request AAK samples. After 45 days, AAK sent 12 hydraulic counterbalance valve samples. Last week, Coleman sent an email to us that the equipment installed with AAK hydraulic cartridge counterbalance valves ran stably without any functional impact. 8 months have passed and the customer has no complaints. I told him that even in another 8 months, the customer wouldn't complain. AAK optimized the hydraulic counterbalance valve with minor changes in 3 aspects, which is not only more stable and better, but also more durable. 1. In the inner chamber of the hydraulic counterbalance valve spool, the boss for axial limit is machined. The piston slides in the second chamber. The rear end of the piston is equipped with a one-way throttling device (the first damper and the second steel ball). 2. The main valve spring adopts multiple spring structures with different stiffness, and the chute on the cone side of the valve spool can control more accurately and sensitively to prevent the load from stalling. 3. The second steel ball is placed in the third chamber of the piston and matched with the valve port of the first damper. The rear end of the screw plug is provided with a damper, which has two damping links. The utility model reduces the system pressure, reduces vibration, is beneficial to stability, and is durable. AAK hydraulic cartridge counterbalance valve, stable and durable, you can also try a small order! https://www.aakindustry.com/info-det , ail/counterbalance-valves-aak436
