Last night while reading, I came across a saying: "No friends with time, only friends with trends." If we apply it to the level of hydraulic cartridge valve manufacturers, it means that hydraulic cartridge valve manufacturers can only make friends with trends, not with time. I feel that this statement is both right and wrong. Hydraulic cartridge valve manufacturers seem to operate at a uniform time, but reality is intertwined with randomness and market uncertainty.   How do hydraulic cartridge valve manufacturers respond to trends? AAK has two methods:   1. We should follow the trend, but we cannot follow the trend and pursue hot topics.   2. Be both calm and vigilant, don't be knocked over by the waves.   The thunderstorm in China's real estate industry is not only caused by unpredictable events, but also by habitual thinking. Everyone always thinks that after the housing price regulation, it will come back and hit new highs. Thunderstorm, because of Trends? Or is it because of common sense? What is common sense? It's something that is not useful when you think it's useful, and useful when you think it's not useful. When you follow common sense, she quietly protects you but doesn't tell you; When you don't follow common sense, she will come out to punish you mercilessly. Munger said, "Everyone knows that common sense is something that ordinary people don't have."   Hydraulic cartridge valve manufacturers follow common sense and are most likely doing the right thing; The common sense of hydraulic cartridge valve manufacturers is also based on empiricism; The common sense of hydraulic cartridge valve manufacturers is a belief based "probability". Ultimately, the beliefs of hydraulic cartridge valve manufacturers are the root cause. Whatever quality beliefs you have, the hydraulic cartridge valve manufacturers have the same quality common sense.   Old hands lose to trends, newbies lose to common sense. Many beginners benefit from trends, but they attribute them to themselves. As a result, successful newcomers often despise everything, even common sense, thinking that they have good talent, and ultimately, they are punished by common sense. Hydraulic cartridge valve manufacturers need to follow the trend and win in a certain cycle; But it depends on following common sense to cross cycles and achieve long-term success. Furthermore, common sense is the ability to cross many cycles. Most hydraulic cartridge valve manufacturers have an instinct to prove their existence and uniqueness, unwilling to accept those "obvious" things. Emerson wrote, "Common sense is the shortest straight line between two points." Sometimes, simple and direct methods are the best, and this is also the power of common sense.   In the world, there is no job that is not hard, and there is no hydraulic cartridge valve manufacturer that is not difficult. No matter what you are currently experiencing, you should follow the trend and not go with the flow, chasing hot topics. Be both calm and vigilant, don't be knocked over by the waves. Every hydraulic cartridge valve manufacturer is not easy, there is no need to regret. If it is beautiful, it is called wonderful; if it is bad, it is called experience! Hydraulic cartridge valve manufacturer AAK, taking advantage of the situation and maintaining vigilance.

A German material scientist, along with a group of travel companions, came to the Amazon region for scientific research. In the evening, they camped on the slope of the Amazon. Although there were some unknown stones, they chose to pitch their tents here to talk about the unknown and mysterious things on this land. When he woke up the next day, the material scientist took out his military dagger and prepared to unload the tent and set out for another destination. His teammates were surprised to find that his military dagger had several small holes, which seemed to have been hit by hard objects, leaving a gap. The material scientist was very concerned about his dagger, and remembered that the dagger fell to the ground several times when pitching the tent yesterday. So the material scientist kept an eye on it and lay down on the hillside where he slept last night, hitting different stones again and again, using his beloved dagger. Surprisingly, he found that there was a stone he had never seen before. Although his beloved dagger had several more marks, he did not care at all. The material scientists collected this kind of stone and took it back to their laboratory for research. They successfully extracted a material and found that it has a very magical effect on the hardness, wear resistance and corrosion resistance of alloy steel. This material is used in the alloy steel for the valve spool of hydraulic valves, realizing the 3 characteristics of wear resistance, corrosion resistance and durability of the valve spool. The valve spool with these 3 characteristic is also the key for AAK hydraulic cartridge valves to open the door of top hydraulic valve brands HydraForce, SUN Hydraulics and HAWE. AAK hydraulic cartridge valve spool, with 3 features, supplying 3 first-line brands, and service life is not less than 3 years. https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-valves-aak478

Some time ago, Lesta from Russia, left a message on AAK website: I saw an article of AAK about “Integrated Hydraulic Threaded Cartridge Valve, AAK replaced 3 HydraForce Valves with 1, which is simplified and cost effective”. This article is similar to the problem I am currently facing. Can AAK customize an integrated hydraulic threaded cartridge valve for me? After communication, it was learned that their lift was complained about by customers for high energy consumption and high price. Their engineers wanted to use an integrated hydraulic threaded cartridge valve to replace various single function hydraulic cartridge valves in the system. They contacted several hydraulic threaded cartridge valve manufacturers in China, but no result. Lesta was very anxious. According to their lift hydraulic system, their engineers are right. Only replace the current solenoid valve, counterbalance valve, Restriction valve and dual pilot-to-open check valve with integrated hydraulic threaded cartridge valve, with fewer valves, the cost can be reduced, the oil circuit is simpler, and the energy consumption is also reduced. Although this customization is different from the integrated hydraulic threaded cartridge valve we customized for Swedish customer, it is not difficult for our technical team. Last week, AAK sent 10 samples of integrated hydraulic threaded cartridge valves. Today we received an email from Lesta informing us happily that the functions of AAK integrated hydraulic threaded cartridge valve are compatible with the lift and it can now function normally. Not only has the cost of procurement decreased by 30%, but energy consumption has also decreased. Their engineers are very satisfied with AAK integrated hydraulic threaded cartridge valve. AAK integrated hydraulic threaded cartridge valve replaced 4 valves with 1 for Lesta. Through integrated design, the check valve spool, poppet valve spool, orificing and magnetic sleeve can be integrated together to complete the lifting and lowering control of the lifting equipment, achieve pressure holding when the lift stops, and simplify the oil circuit. We do this way: 1. The valve body has axial perforations, a third oil port is located on the middle sidewall, and the left end of the valve body is connected to a magnetic sleeve component. The valve hole is connected to the third oil port, forming an annular first passage flow groove. 2. The right end of the conical valve spool slides and fits with the valve hole, the left end extends into the balance chamber, the right end is equipped with a second flow groove, and the right end is processed into a conical surface to seal the valve hole. The check valve spool slides and is located in the installation chamber, with a third flow hole connected to the first oil port. 3. The valve seat is connected to three cylindrical segments with decreasing diameter at the right end of the valve body inner hole. There is a stepped concave part and a second through-hole in the valve seat. The orificing is located inside the second through-hole and is also equipped with a throttle hole. AAK integrated hydraulic threaded cartridge valve, reduces procurement costs and energy consumption, and you can also give it a try!

Maverick comes from a hydraulic equipment company in the United States. He has been very successful in the purchase of hydraulic valves, but fell over on the hydraulic check valves purchased last year. At the end of last year, the hydraulic system of a batch of excavators shipped to Vietnam was prone to heat, and the output power was insufficient and unstable. Users were very dissatisfied with such excavators. According to the working conditions of the excavators, the after-sales engineer judged that the hydraulic check valves were abnormal. After disassembling the hydraulic check valves, it was found that the tolerance of form and position of the valve spool and the valve hole is inconsistent, and it was also found that the valve spool was stuck, causing the excavator to be abnormal. The engineer asked Maverick to replenish 50 hydraulic check valves to solve user complaints. Maverick contacted the original manufacturer of the hydraulic check valves, and the manufacturer agreed. A week later, the engineer replaced the abnormal hydraulic check valves, but 10 days later, another excavator had the same abnormality. At this time, Maverick realized the problem. No one could accept the long-term and high-frequency after-sales replacement, so he had to find a new hydraulic check valve manufacturer. Maverick left a message on AAK website: can you ensure that each hydraulic check valve has no abnormal problem within the warranty period? I replied, "I'll let you know if it's OK. You can try it out.". The next day, Maverick placed a trial order for 50 hydraulic check valves and mentioned to avoid the hydraulic system heating. I told him that the hydraulic check valve used to control the oil return in the hydraulic system is connected with the hydraulic oil radiator and connected to the outlet of the oil return filter element. If the hydraulic check valve is stuck in the normally open position, the oil return radiator will not play the role of heat dissipation. As long as it is not stuck, the hydraulic system will not be easy to heat up. 6 months after the 50 hydraulic check valves were shipped, I received an email from Maverick today. After install the excavator with AAK hydraulic check valves, the excavator was still normal after 6 months. The customer was very satisfied with their after-sales service to completely solve the problem. I smiled and said that as long as there is no artificial mistake, even after another 6 months, these excavators equipped with AAK hydraulic check valves will not have complaints caused by hydraulic check valves. For the hydraulic check valves, the consistency of the form and position tolerance between the valve spool and the valve hole is the key to directly determine whether the whole valve will be stuck. AAK hydraulic check valves can achieve 100% qualification. The most important reasons are as follows: 1. AAK has Germany Nagel precision honing machine. After honing, the dimensional accuracy of the valve spool and valve body of the hydraulic check valves is IT7 ~ 4, and the form and position tolerances are completely consistent, which is impossible for most manufacturers. 2. Check the accuracy of each hydraulic check valve spool and valve hole to ensure that the minimum axial grinding tolerance is 0.075μm. Thus, each hydraulic check valve can achieve 100% no jamming. Manufacturers with such precision control will not exceed 3 in Ningbo. 3. AAK technical team has engineers from the world's top 500 hydraulic valve enterprises, who have their own experience in material selection, production drawing design and production line quality control. Maverick told me privately that his boss appreciated that he could find such a reliable hydraulic check valve manufacturer AAK this time, and the boss would give him a raise. AAK hydraulic check valves, the form and position tolerance is consistent without jamming, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak245

Hydraulic cartridge valve manufacturer AAK, although it is a production line operation, still has many daily issues. Early this morning, sales representative Xiao Li complained to me that after a month of working with a hydraulic cartridge valve customer, the contract was signed, but there was no further news when entering the payment stage.10 minutes later, the workshop director complained that the young production line workers are difficult to manage. They seem to feel that it is too difficult being hydraulic cartridge valve manufacturers. I didn't answer their questions and shifted the topic, telling them how easy it is to complain. Why did you do something easy? Roast is so easy. Why do you do roast? Complaining and spitting is not about not being able to vent, but after long- term depression, you will find that you can no longer gather yourself together and find no motivation to move forward, like a dying flower. So, hydraulic cartridge valve manufacturer AAK can fall, but don't lie on the ground. It can be sad, but don't indulge in emotions. We are born with a conscience, and the answer is in your heart. After a contract is signed, if customers do not wire the payment to hydraulic cartridge valve manufacturer, either something goes wrong or they cannot afford it. The separation at the beginning may be a good thing for hydraulic cartridge valve manufacturers. One day, your joy will not be magnified by others' praise. Your sadness is not magnified by the belittlement of others. Don't be not pleased by external gains, not saddened by personal losses, stay calm when encountering problems, and when you ask for answers from your heart, you begin to become stronger. Whether being sales in a hydraulic valve factory or managers in a hydraulic valve manufacturer factory, if you can understand the truth and do things well, that's growth. If you have to figure it out before doing it, then the trouble for the hydraulic cartridge valve manufacturer will come. On the contrary, knowing in action, act in knowing. Cook's speech at Stanford University, "You can never be ready," just conveyed this meaning. Everyone has good or bad times, and the subtext is that people need to adjust themselves. So, start first, then adjust your breathing; Take off first, then adjust your posture. Think, only difficulties; Doing is the answer. The ancient sages have said that we must first build virtue, the second must build meritorious deeds, and the third must build one's ideas in writing. What is virtue? Virtue is self-cultivation and self restraining. Continuously overcoming one's own inner self and overcoming this era in oneself. The ancient people's 3 builds were also the requirements of hydraulic cartridge valve manufacturer AAK for themselves. Some hydraulic cartridge valve manufacturers, when introducing their products to customers, talk extravagantly, but the subsequent execution is in a mess. This is a typical example of without "3 builds”, which not only violates the teachings of the ancients, but also violates their own conscience. In the hydraulic cartridge valve manufacturer AAK, despite sudden customer situations and difficult management of young frontline operators, should I give up? Should we just despair? The ancient people's 3 builds will tell you that despair is just a state of mind, and the answer is in your heart, and you should seek the cause in yourself. The 3 builds of the ancients, the thinking of this, and the conclusion of this are like crossing time and space, crossing the darkness of light. Because the night is long, the light of dawn appears so precious. China Hydraulic cartridge valve manufacturer AAK's 3 builds, is for itself and also for customers.

Samuel is from OLEODINAMICA REVA SRL company in Italy. He has purchased a non- standard hydraulic relief valve from AAK for 2 years, and re-peat the orders 3 – 4 times every year. He didn't expect that in order to save 20% of the cost, the hydraulic relief valves purchased from a new manufacturer was complained by customer for insufficient power within only half a year. This hydraulic relief valve is used in the top 3 hydraulic power unit they sell. There have been no complaints in the past 2 years. The root cause of insufficient power is that the main valve element of the hydraulic relief valve is stuck, causing the pressure oil output by the hydraulic pump to overflow back to the oil tank, affecting the power. Samuel contacted the new manufacturer of the hydraulic pressure relief valves. The manufacturer replied that they can only guarantee the service life of more than half a year for 450bar high-pressure working condition and high-frequency use hydraulic relief valves. This hydraulic relief valve is benchmarked to German HAWE. Perhaps only HAWE high-pressure hydraulic relief valve has a service life of more than 2 years. The hydraulic relief valves produced by the new manufacturer have only half a year of service life, and Samuel felt helpless. The boss can not understand why Samuel blindly changed the manufacturer without knowing the service life of the hydraulic relief valve. This hydraulic relief valve has been customized by AAK before. The equipment has been used for more than 2 years without customer complaints. Samuel had to contact AAK again and truthfully told us that in August last year, another manufacturer provided a quotation of 20% cheaper than AAK, so he moved the order of this hydraulic relief valve to the new manufacturer. Now, those hydraulic relief valves need to be replaced, he needed AAK’s help to produce 100 hydraulic relief valves quickly. I immediately asked the workshop to produce 100 hydraulic relief valves at once. The workshop director said it was not worth adjusting the production line for such a customer with low loyalty. But it is the responsibility of AAK to solve problems for customers. At the same time, I am grateful to this new hydraulic relief valve manufacturer. I believe Samuel will never transfer orders from AAK again. After 3 weeks, 100 hydraulic relief valves were successfully shipped from AAK. Samuel emailed a few days ago that the power of the equipment was normal after AAK hydraulic relief valves were used. AAK high-pressure hydraulic relief valve can be benchmarked with German HAWE due to 3 key points. It may be difficult to find such a second hydraulic valve manufacturer in Ningbo. 1. AAK hydraulic relief valve element material is ETG100 produced by STEELTEC in Switzerland, with high strength. It is suitable for high-speed CNC processing. After the valve element is processed and formed, the internal and external cross-sections have the same strength and can withstand high pressure above 450bar. Less than 1% of the manufacturers are using ETG100 to produce valve element. 2.AAK has a high-precision CNC machining center imported from Switzerland. AAK old technicians can control processing efficiently and without mistakes. This unique skill may only be in AAK. 3.AAK technical team has engineers who have worked in HAWE for many years and have unique experience in high pressure resistance. AAK hydraulic relief valve, under 450bar high pressure, can be used for more than 2 years. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak244

Last week, we mentioned that the hydraulic directional control valve cage of Ra0.8 and roundness tolerance of 1μm, a customer Jhon from Mexico left a message to us: Can AAK produce hydraulic pressure control valve with valve cage accuracy within 2μm? Many hydraulic cartridge valve manufacturers in China are not very focused on the accuracy of valve cages because the domestic market is used to it. It is not very difficult to produce the hydraulic pressure control valve with cage accuracy within 2μm. We have similar customer requirements, whether it is for hydraulic directional control valves, hydraulic pressure control valves, or hydraulic flow control valves. We will select suitable machine tools for production based on the production situation in the workshop and customer requirements. When new customers ask if AAK can achieve any precision or specific requirements for hydraulic cartridge valves, this is an opportunity for hydraulic cartridge valve manufacturer AAK, as it is highly likely that customers have encountered difficulties with other hydraulic cartridge valve manufacturers. For Jhon's message, I sent him a video, which may be more convincing. Although he received our video on Monday and did not reply on the same day, I believe he will send an inquiry. For hydraulic pressure control valves with cage accuracy within 2μm, AAK can choose the Hardinge CNC machine tool from the United States as shown in the video. The overall structure adopts a 45 ° inclined bed. When we installed it, we filled the equipment cavity with marble. The advantage of this is that it avoids the occurrence of small vibration lines on the surface of the workpiece due to the impact of vibration waves on the continuity of the tool during the cutting process, which affects the accuracy of the valve cage. From the video, it can be seen that the entire cutting process is carried out in a stable and almost vibration free condition. The machine tool is also equipped with 20 knives and can produce hydraulic pressure control valves of different models. Today, we just received an inquiry from Jhon for a hydraulic pressure control valve with drawings, hoping that we can secure another customer from Mexico. AAK hydraulic pressure control valve, valve cage accuracy within 2μm, you can also try a small order!

Janice, from Canada, wants to purchase 600 hydraulic relief valves. The core difficulty of this hydraulic relief valve lies in the processing of valve elements. Most factories can only bemoan their inadequacy for the valve elements with inclined holes and included angles. The American hydraulic relief valve manufacturer who has been cooperating with Janice has failed 4 times in 30 days and had to surrender. Janice found more than 20 hydraulic relief valve manufacturers online and offline, at home and abroad, but they either replied that there was no time for sampling or no response. Janice has been tossing about for a week and is a little frustrated. Pablo, an old customer of AAK, after learning about Janice's procurement problems, suggested that she send the hydraulic relief valve drawing to AAK for a try. Pablo also specially wrote me an email to ask AAK to help Janice. I am willing to try to solve such a difficult problem of hydraulic relief valve. Once it is solved, I have won the admiration of two people at the same time. According to the hydraulic relief valve drawing sent by Janice, except for the valve core, other requirements are also conventional. The valve core of this hydraulic relief valve is different from the conventional straight hole valve core, which is marked in the drawing Φ4- Φ3.7mm inclined hole, and the axis line of the Φ3.7mm hole forms an included angle of 60 ° with the axis of the valve core parts. It is difficult and requires high precision in the clamping and positioning process of hole processing. The hydraulic relief valve manufacturers without high-precision equipment and over 15 years old technicians will fail even if they try to make samples for 100 times. AAK technical team discussed for 2 days, and they were 70% confident that the sample would be successful. Although Janice is a little disappointed, it is also the best news she has received recently. She is in urgent need of this hydraulic relief valve. AAK has been brainstorming for 2 weeks, constantly changing the material of the hydraulic relief valve core, adjusting the process parameters, and sending the hydraulic relief valve sample for the first time. After 5 days, Janice informed that there was an error of 0.1% in the inclined hole of the hydraulic relief valve spool. AAK carried out the second hydraulic relief valve sample and optimized the process again on the high-precision turning milling composite locomotive to improve the accuracy of the inclined hole. A few days after AAK's second hydraulic relief valve sample was sent, Janice sent an e-mail. The American manufacturer spent 4 weeks on this hydraulic relief valve, but all 4 samples failed. She tossed and turned for a week and failed to find a hydraulic relief valve manufacturer that dared to make samples. However, AAK succeeded in 2 proofing within 2 - 3 weeks. AAK high-precision turning milling compound machine tool is the core of the success of the sample. This machine tool is equipped with upper and lower tool towers. The main shaft can be 360 ° indexed. The upper shaft is the milling main shaft, with a rotation angle of 225° and 40 tools. At the same time, it can complete the machining of axial hole, radial hole, inclined hole drilling and reaming, inclined groove and tapping under one-time clamping. The key to the success of AAK sample is our old technician, who has 32 years of practical operation experience. With specially assigned person and special machine, AAK has unique skills in turning and milling compound machine tools. AAK hydraulic relief valve, valve element with inclined hole and included angle can also be produced.

Alexandro is from a logistics equipment company in Brazil. At the end of last year, they developed an airport logistics equipment, which will be promoted at this year's exhibition. Unstable pressure supply and slow response occurred in the commissioning stage, because the inlet and outlet oil flow of hydraulic manifold is unstable. Test each hydraulic valve in the hydraulic manifold separately, and there is no abnormality. Their technical team did not have a solution, but only asked Alexandro to re purchase hydraulic manifold. Alexandro knew that blindly re purchasing hydraulic manifold was tantamount to changing the form but not the content. After consulting the manufacturers of the original hydraulic valves and hydraulic valve blocks, they all said that they are unable to analyze the whole hydraulic manifold, but they can ensure that their products have no problems. Alexandro is also consulting other hydraulic manifold manufacturers. A week has passed and no reply has been received. The boss also blamed Alexandro for the poor hydraulic manifold in purchasing, and Alexandro was unable to say the suffering. Alexandro accidentally browsed AAK in Google and left a message: why is the pressure supply of hydraulic manifold unstable? Such questions are not specific and difficult to answer. It is just like the question, what is the cause of a child's fever? A blood test is needed to determine whether it is a virus or a bacterial infection. According to the hydraulic manifold drawings and video of commissioning provided by Alexandro. AAK engineers judge that the problems lie in the design of hydraulic manifold and the selection of hydraulic valves. I replied to Alexandro that AAK can redesign the hydraulic manifold, but it takes 40 days and 6,000 US dollars of development cost. If it fails, the fee can be refunded. The promotion time is coming, the boss is pressing, but he still can not find a new factory. Maybe Alexandro has to only believe in the hydraulic manifold of AAK. After 40 days, AAK sent the hydraulic manifolds. 1 month later, Alexandro informed that the hydraulic manifold newly designed by AAK had been used for 3 weeks, and the equipment was normal. Hydraulic manifold design runs through the whole process of design, manufacturing, use and maintenance, especially affected by manufacturing, that is to say, a good hydraulic manifold design cannot be separated from manufacturing. AAK often receives some hydraulic manifold drawings that cannot be processed directly according to the drawings. A good hydraulic manifold designer must be able to analyze the whole manufacturing process. AAK hydraulic manifold engineers consider not only manufacturing, but also the use, because the design is for "use”, such as hydraulic manifold efficiency, energy consumption, stability, service life, and maintenance methods. Innovation is also needed in hydraulic manifold design. AAK hydraulic manifold innovation means that each hydraulic valve is re combined into a new hydraulic manifold, or some new elements are added to the old hydraulic manifold. New things are generated in affirmation and negation, and negation and affirmation. Innovation is just like seasoning. With such a little seasoning, the dish tastes more delicious. AAK hydraulic manifold runs through the whole process of design, manufacturing, use and maintenance. You can also have a try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-aak242

Today, Eichendorff from Germany placed a re-order for 500 hydraulic pilot operated pressure control valves and told us that his boss was very satisfied with the quality of AAK. It has been more than 1 year since the last purchase of hydraulic pressure control valves, and no customer complained about unstable pressure supply. At the beginning of last year, one of their hydraulic power units was complained by customers that the pressure supply was often unstable after using a period of time. They judged that there was a problem with the hydraulic pilot operated pressure control valve. After the valve was replaced, the pressure supply of the equipment was normal. Eichendorff sent the replaced valve back to the original hydraulic pressure control valve manufacturer. After inspection, the manufacturer found that the parameters and functions were produced according to the requirements of Eichendorff's company. He thought that they had moved the pressure regulating screw of the hydraulic pressure control valve during installation. After measurement, Eichendorff's engineers found that all parameters of the original hydraulic pressure control valve could be benchmarked, but they did not change the pressure regulating screw during installation. Eichendorff contacted several local German hydraulic pressure control valve manufacturers, and most of them were unwilling to analyze. After browsing AAK website on Google, Eichendorff sent an email and asked: what is the reason for the unstable pressure supply of the hydraulic pressure control valve after using a period of time? AAK HYDRAULIC VALVE often receives similar questions, and we are happy to solve these problems, because this is the best source for accurate customers. Eichendorff sent us the samples, drawings and hydraulic system schematic diagram of the hydraulic pilot operated pressure control valve the next day. 1 week later, AAK engineers disassembled the hydraulic pressure control valve and found 2 possibilities in combination with various technical parameters. First, the design of the damping hole of the hydraulic pilot operated pressure control valve should be improved. The ratio of the opening pressure to the set pressure is a little high, which will cause too large pressure regulation deviation, thus affecting the stability of the valve. Second, the type selection of the spring of the hydraulic pilot operated pressure control valve is not suitable, and a spring with better elasticity is required. After receiving our diagnosis, Eichendorff hoped that AAK could test the samples according to our ideas and was willing to pay the development cost. AAK technical team spent 24 days and tried samples for 6 times, and found the most suitable pressure ratio, adjusted the original design of the damping hole, selected 3 springs with good elasticity to compare, and determined the special SiCr alloy steel spring as the spring of the hydraulic pilot operated pressure control valve. After 30 days, 30 samples were sent. 3 months later, Eichendorff informed by email that when AAK hydraulic pilot operated pressure control valve was used, no customer complained about unstable pressure supply. I replied that according to previous customer feedback, there will be no customer complaint about unstable supply within 1 year. Eichendorff probably didn't believe it until 1 year later, today, the reorder of the hydraulic pressure control valve came. Eichendorff admired AAK service and professionalism from the bottom of his heart. AAK hydraulic pressure control valve is not only professional, but also good at what peers are unwilling to do. Welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-control-valves- aak257

This Monday, we launched a new model E-CXBA free flow nose to side check valve, which is equivalent to SUN's standard parts CXBA. This Free-flow, nose-to-side check valves are on/off circuit components that allow free flow from the inlet (port 1) to the outlet (port 2) and block flow in the opposite direction. Many hydraulic manifolds use this hydraulic check valve, and most hydraulic manifold manufacturers do not have the production procedure of this hydraulic check valve. They need to purchase this hydraulic check valve from other hydraulic cartridge valve manufacturers. AAK has provided this hydraulic check valve to 5 customers for use in their manifolds, or directly supplied the complete hydraulic manifolds with this check valve. This hydraulic check valve is not only widely used, but also has many functional requirements. The key lies in its performance. Although some cartridge valve manufacturers can produce this hydraulic check valve, and perhaps its functions can be compared to SUN's CXBA standard parts, how is the performance of their hydraulic check valve? AAK E-CXBA Hydraulic Check Valve 2 Key Selling Points: 1. The lifespan is twice that of most peers 2. Low leakage, internal leakage of 1 drop/min, benchmarking SUN for both functionality and performance. Technical parameters of AAK E-CXBA Hydraulic Check Valve: Maximum Operating Pressure: 350 bar (5000 psi) Capacity: 10 gpm (40L/min) Internal Leakage: 1 drops/min. Cavity: T-162A AAK has supplied this hydraulic check valve to 5 customers for their hydraulic manifolds, and you can also give it a try.

Consuelo comes from Spain and started purchasing hydraulic cartridge valves from manufacturers in China 2 years ago. He has been successful but was wrestled by a hydraulic cartridge relief valve equivalent to HydraForce RV10- 22. The cartridge relief valve thread slipping caused by carelessness in the original hydraulic cartridge valve manufacturer was solved by AAK with 1 small detail. In March of this year, they needed to purchase 100 pcs of hydraulic cartridge relief valves RV10-22. This is a standard part, and Consuelo purchased RV10-22 in bulk directly. 3 months later, some users complained that the threads of the hydraulic cartridge relief valve cage were slipping and leaking. Consuelo was surprised because this is the first time for him to encounter this low-level error of thread slipping. Although the original manufacturer of the hydraulic cartridge relief valve was very cooperative, Consuelo realized that the hydraulic cartridge valve manufacturer with unstable quality would bring him a lot of trouble in his future work. Each hydraulic cartridge relief valve cage thread must be 100% compliant without slipping threads. Consuelo found AAK on Google and left a message: Has AAK encountered any problem with the thread slipping of the hydraulic cartridge relief valve cage? I told him that more than one client has raised the issue of thread slipping, and AAK has avoided thread slipping with just a small detail in the process. After communication, it was learned that he purchased hydraulic cartridge relief valve RV10-22 from the original manufacturer and encountered the problem of thread slipping. I told him that AAK has existing stock for the hydraulic cartridge relief valve RV10-22. He can receive them after 1 week and customer complaints can be resolved. The hydraulic cartridge relief valve thread has no slipping, which is not difficult, but the key lies in the details. Of course, the material selection and processing of hydraulic cartridge relief valves are the foundation. AAK controls the accuracy of the valve cage external thread and internal hole inspection in this way. Before assembly, AAK inspection technicians use thread ring gauges and plug gauges to check. Inspect the thread size on the outer surface of each hydraulic cartridge relief valve cage using a thread gauge. The inner diameter of the hydraulic cartridge relief valve cage is tested with a plug gauge, and each thread is tested. This is a small detail, but most hydraulic cartridge valve manufacturers in China overlook this process directly. The original manufacturer was unable to avoid the thread slipping of hydraulic cartridge relief valve RV10-22, and AAK solved it with one 1 small detail. AAK hydraulic cartridge relief valve, the thread without slipping, you can rest assured to give it a try!
