Valves

Yesterday morning, a colleague complained to me that he couldn't stand the Indian hydraulic valve customer. After communication, I learned that this old customer had to bargain every time when he placed the reorders, and he had asked for price reduction for 3 times. This time, this colleague couldn't bear it. There is an old Chinese saying that there is no need to bear it anymore. It seems to explain the legitimacy of the actions: I can't stand it. I have to do so. In fact, what you do when you can't bear it, whether it's right or wrong, good or bad, you shouldn't do it. What is the goal of AAK hydraulic valve? Isn't there more and more choice in the hydraulic valve industry? Specific to everyone of AAK hydraulic valve is to avoid making themselves have no choice. To be unbearable is to admit that you have fallen into a state of no choice. Think about my colleague carefully. Why didn't he have a choice? People often ask: is effort more important or choice more important? It is said that when you have a choice, choice is more important. If my colleague can insist on marketing like other colleagues and has more than 3 old customers of hydraulic valves, is there a better choice? And when you have no choice, hard work is important. In terms of specialty, adhere to the output of professional contents in hydraulic valve, and move towards the direction of technology and process; In terms of service, stick to the direction of trust. Combine the two, you don't need to worry about having no choice. In fact, there is another extension of this answer, that is, what is the purpose of efforts? Just to make yourself more selective. What is the AAK hydraulic valve effort for? In order to make ourselves have more choices to do a good job of hydraulic valves. AAK hydraulic valve adheres to the choice of subdivided target customers, and serves customers well with AAK hydraulic valve's distinctive advantages or distinctive technical features. AAK hydraulic valve adheres to a group of people, a lifetime and one thing, so that each user can make good use of AAK hydraulic valve. AAK hydraulic valve adheres to the principle of integrity, does a good job in the business of AAK hydraulic valve, and sincerely treats every customer who purchases hydraulic valves from AAK. Let more customers use good hydraulic valves with real materials without wasting money. I told my colleague that you should treat the client as your girlfriend. For example, she offered to break up with you today, and you gave her your last speech. If she understands your mind, she will come back. If she doesn't come back, it means she's not suitable for you. He sent an email to the Indian hydraulic valve customer: when you asked a price reduction of this hydraulic valve for the first time, and I gave you 5%. AAK treats the quotation of each hydraulic valve in good faith, and does not falsely quote the price, and does not arbitrarily quote the price, which is an expression of dishonesty in itself. For the second time you reduced the price of this hydraulic valve, I gave you 2%. This 2% is my business commission, that is to say, for the second order of hydraulic valves, I serve you free of charge. I gave you another 2% of your third hydraulic valve order. I told the finance that I would pay for the 2% price difference myself, because I had to complete the annual business key performance indicators (KPI). Your 4th order of hydraulic valve will cut my price again. I not only don't earn a penny, but also pay for the keeping of an unprofitable business. I have to eat, too. I have no food to eat. How can I serve you? I hope you can take care of me to eat, so I have the confidence to serve you well. Surprisingly, today, this Indian hydraulic valve customer placed an order at the original first price. AAK hydraulic valve is not only different, but also miracles. You can also have a try. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak174

On the first day of March, Chris from an industrial solar energy company in the United States sent an inquiry about the hydraulic check valves. This is the first email from Chris to AAK. I'm not sure where she learned about AAK and got the email address. After further communication, we knew that she wanted to purchase total 1,100 hydraulic check valves of two styles. The next day, she sent the detailed drawings and working condition requirements of the hydraulic check valves to be purchased. Chris needed us to quote urgently. She has contacted many hydraulic check valve manufacturers, but the lead time can not meet her requirements, she hoped that AAK hydraulic valve can ship as soon as possible. AAK engineer analyzed her hydraulic check valve drawings and working condition requirements, and soon matched the production procedure in AAK database. Coincidentally, this is the same as the hydraulic check valve purchased by one of our Indian customers, but only the sealing ring is different. Every time, the Indian customer always needs goods urgently, and the quantity is sometime large and sometime small, so we often produce some flexible stocks to meet the immediate demand of this Indian customer. After receiving her hydraulic check valve drawings and working condition requirements, AAK offered the price and 7-day delivery time on the same day. Unexpectedly, Chris sent us the bank slip for the full payment. In addition to surprise, we realized that this customer were in urgent need of this batch of hydraulic check valves. We arranged to send approval samples immediately, but the customer said that it was not necessary to send the samples for approval, because the drawing parameters of the hydraulic check valve provided by AAK were consistent with their needs. She hoped that we can change the sealing rings and air freight the goods via TNT as soon as possible at her expense. It is our principle that if customers treat us with A, we will reward them with A + +. Our workshop organized people to replace the sealing rings of hydraulic check valves immediately, and purchased the master cartons as soon as possible, and shipped it in 3 days. When we sent the shipping photos and airway bill of the hydraulic check valves to the customer, she used 3 thanks to end the purchasing of the hydraulic check valves. Without seeing the samples, but advance the full payment directly when quote is just received, which is the first time I met. Although it is only a small order of more than 5,000 US dollars, behind it is the customer's trust in AAK hydraulic valve. In this era, the most expensive thing is not gold and diamonds, but trust. Once the problem of trust is solved, business is a natural thing. All things that can enhance trust should be done more and desperately, which is what AAK hydraulic valve has always insisted on doing. If you do something to enhance trust, you don't worry about having no customers. AAK hydraulic valve builds confidence in good times and combs quality in bad times. The more we face uncertainty, the more we should insist on doing the right thing and try our best to enhance trust. AAK hydraulic check valve is not only fast, but also stable.

This week, we’d like to introduce a Hydraulic Screw-in Counterbalance Valve equivalent to SUN standard part CBGG. The 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. A customer in Spain sent us inquiry for this counterbalance valve last September, with annual qty of 600 pcs. However, after we quoted the price, there was no any feedback. The customer sent us inquires for other SUN cartridge valves at later times. Every time, there was no any feedback. Unexpectedly, this March, the customer got back to us and placed the trial order of 10 pcs for CBGG. Until that time, we learned that AAK prices were 5% - 10% higher than other hydraulic cartridge valve manufacturers in China every time, so he placed the orders with other manufacturers. However, the quality of hydraulic cartridge valves he purchased from other hydraulic cartridge valve manufacturers in Ningbo was not stable, he was very frustrated, so he wanted to test AAK quality. We delivered the 10 pcs of test samples. Last week, we were very happy to learn that AAK samples passed the testing. They are still performing very well after 9 months of use. The customer placed their annual order with AAK finally. It has been 15 months since we received the inquiry for this counterbalance valve CBGG. AAK hydraulic counterbalance valve 2 advantages: 1.

Senon is from a Spanish hydraulic equipment company and has been responsible for the procurement of hydraulic valves for 3 years. At the end of last year, their customer customized two sets of hydraulic power units for ocean ships, and needed to customize the hydraulic cartridge counterbalance valves. Senon chose a hydraulic counterbalance valve manufacturer who has cooperated for 3 years to make samples. During the equipment commissioning, it was found that the pressure supply was unstable and the hydraulic system was tested separately, but there was no abnormality. The boss questioned the team's performance. Senon felt that there was a hidden danger in the original design of the hydraulic cartridge counterbalance valve, but the engineer thought that the function of the purchased hydraulic counterbalance valve was not up to the standard, so both parties tried to shift the blame. Senon contacted other manufacturers of hydraulic counterbalance valves. 2 weeks passed, it was fruitless. Senon became very anxious. When browsing on Google, Senon found AAK webpage and left a message: Is the instability of hydraulic cartridge counterbalance valve caused by a hidden danger in design or an unqualified precision? I replied: both possible, it needs to analyze specific problems. He sent me the equipment debugging video, the production drawings of the hydraulic cartridge counterbalance valve, and also told me the name of the original hydraulic counterbalance valve manufacturer. In my opinion, it is unlikely that the original manufacturer can not control the manufacturing quality of this hydraulic cartridge counterbalance valve. I told him that probably the design function was abnormal, and the manufacturing defects of the original manufacturer were not ruled out. Senon seemed confused and asked me for advice. I told him that AAK was 90% confident to solve the instability of the hydraulic cartridge counterbalance valve and improve the equipment pressure supply. After 40 days, AAK sent 10 hydraulic cartridge counterbalance valve samples. 3 weeks later, Senon emailed that the unstable pressure supply that had troubled him for 6 months, had been solved by AAK at one time. He could relax finally. The two sets of the hydraulic power units had been delivered to the customer. He was waiting for the customer's regular order. Their engineer also admired the design mind of AAK. The Hydraulic cartridge counterbalance valve designed by AAK, was successful in below 3 points (1 wear-resistant, 2 optimized): 1. A damper is arranged at the oil port at the rear end of the screw plug, the valve spool is provided with an inner cavity that is axially penetrated, and the inner cavity is provided with a boss that is axially limited. This can effectively reduce the flow resistance and improve the wear resistance of the valve spool. 2. The inner chamber of the valve spool is also equipped with a spring, the other end of the spring is against the end cover, the piston is sliding in the second chamber, and the stepped end of the piston rod passes through the chamber wall between the first chamber and the second chamber, to ensure the stability of the hydraulic cartridge counterbalance valve. 3. The back end of the piston is equipped with a one-way throttling device, and the diameter of the outer circumference of the valve body from the end cap end to the screw plug end is gradually reduced in a ladder shape, further optimizing the stability of the hydraulic cartridge counterbalance valve. AAK hydraulic cartridge counterbalance valve, high stability, no worry, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-counterbalance- valves-aa , k395

Duden is from Lukas hydraulic equipment company in Germany. We have cooperated for more than 2 years on hydraulic check valves and hydraulic throttle valves. The order volume is small each time, but the parameter requirements are very high. AAK never despised it because of the small order quantity of the hydraulic check valves or hydraulic throttle valves. At the end of last year, their company developed a new hydraulic unit. Due to time constraints, Duden purchased hydraulic check valves and hydraulic throttle valves from local hydraulic valve manufacturers in Germany. The technicians found the original design defects after installing the integrated valve into the equipment. The position of the hydraulic throttle valve next to the hydraulic check valve is high, accounting for a little position of the motor, which makes it difficult to install the motor. Lukas engineers are a little depressed. If the position of the hydraulic throttle valve is changed, the whole oil circuit layout needs to be changed, but the power supply of the hydraulic system will be affected after changing the oil circuit. What is more troublesome is that there is not much time to redesign and proofing. The Engineers asked Duden to contact some local hydraulic valve manufacturers to check if the design size of the hydraulic throttle valve could be slightly adjusted so that the motor could be installed. Duden checked with several local hydraulic valve manufacturers, all of them were not willing to make samples because of small quantity of the hydraulic throttle valves. Duden tried to purchase small-size hydraulic throttle valves from China to solve the installation problem of the motor. Some Chinese hydraulic valve manufacturers said that they could make samples according to the requested size of their hydraulic throttle valves, but the time needed was more than 30 days. Duden couldn't accept this time and was more worried about the quality of hydraulic throttle valves from these factories. Duden sent an email to AAK asking if we could make several samples of hydraulic throttle valves in 5 days. In the past, the sample time gave by Duden was usually flexible with more than 2 weeks. After asking, I learned that their designers are facing embarrassment. It is also too tight for us to make several hydraulic throttle valves in only 5 days. I suggest Duden give us the overall layout of the integrated valve block. Maybe our engineer has a solution. According to the hydraulic schematic diagram provided by Duden and the specific use of the hydraulic integrated valve block, AAK engineers analyzed it step by step. Finally, it was found that if the hydraulic throttle valve and the hydraulic check valve were designed in parallel, the functions of the two valves were combined to form a hydraulic throttle check valve, which was installed at the position of the hydraulic check valve, and the installation hole of the hydraulic throttle valve was blocked with a plug. This not only saves the redesign time of the hydraulic integrated valve block, avoids the embarrassment that the motor can not be installed, but also has no impact on the pressure supply of the hydraulic system. Their designer was surprised that AAK used this idea to solve the pain point. He hoped that we could make the samples to test as soon as possible. AAK sent the newly designed hydraulic throttle check valve to Duden. After installing the hydraulic throttle check valve into the integrated valve block, the results were as described by AAK, and the test was successful. The design engineers of Lukas company admire AAK unique design scheme and production capacity greatly. AAK hydraulic throttle check valve can efficiently and timely solve problems for customers.

This Saturday, I was sorting out articles on hydraulic cartridge valves in my study. Suddenly, a loud and clear sound came from the living room. Upon running out, my favorite celadon vase fell to the ground, with fragments scattered all over the ground. My 6-year-old son stood in the living room, staring at me, bewildered. Looking at the debris all over the ground, my blood surged up and I shouted at my son. The first time my son saw me get so angry, he was scared and desperately tried to find a reason to explain why the vase fell to the ground, but also to shirk his responsibility. Looking at the tears on his face, I suddenly remembered the instinct of human nature: "When people are afraid, the subconscious action is to avoid, find reasons, and shirk responsibility." I also realized that it was wrong for me to get angry. Returning to my study, I blamed myself for not holding back my anger. Next time I encounter something similar, I must hold back. During my reflection, I summarized the 3 steps. The first step is to take it easy. I should first see if my son is injured. If he gets hurt, go to see a doctor. If there is no injury, clean the debris on the site to avoid secondary injury. The second step is to control emotions and analyze the reasons. Ask my son, why did the vase fall to the ground? If I am gentle, and child is also gentle. He may tell me, "I'm sorry, I just threw the toy around and accidentally broke the vase.". The third step is to eliminate root causes. The celadon vase has broken, and if I don't give up, what else can I do? I can talk to my son like this: Steven, this vase is worth more than 10,000 yuan, and it's also Dad’s favorite vase. Now, it's broken. What do you think to do? He may say, 'I'll give you all my lucky money and buy another one.'. How can we avoid this happening again in the future? He might say, "I won't throw things around anymore.". What if I throw it around again? You can punish me. Son, the important thing is not punishment. Violence cannot solve the problem. Instead, think about what this event has taught you, or what risks it may bring to you, and how we can avoid them in the future. If a celadon vase hit on your head, it will bleed and hurt, which is something Dad doesn't want to see. You can think about what behaviors may bring risks to you and what items at home may harm you. Let's change our behavior together, okay? Seeing and recognizing children, helping them provide feedback, and constantly correcting their behavior. It is like a seed, constantly giving sunshine, rain, and dew, and patiently fertilizing. Until one day, the seeds broke through the soil and grew into towering trees. This is my reflection and summary of the 3 step method. This morning, I opened my mailbox and checked my customer's email. I saw Tim's complaint. AAK sent him samples of a hydraulic cartridge valve test order, which was not the model he wanted. I immediately wondered if another customer's hydraulic cartridge valve sample was sent to Tim by mistake. In the past, I would immediately call my colleagues and hurl insults at them. But yesterday's experience of scolding my son told me that the more I scold my subordinates, the less guilty they will feel. I used the 3 step method to do this way: The first step is to deal with the problem. I apologized to Tim first, and within a week, I will send him the test order samples of his customized hydraulic cartridge valve. I also asked him to return the wrong hydraulic cartridge valve samples, and I will bear all the costs. At the same time, I also emailed to the other customer and told him that the wrong test order samples for the hydraulic cartridge valve were sent to him, and asked him to return the samples. I will bear all costs. Step 2: Analyze the cause. For example, two different hydraulic cartridge valve test order samples may be delivered at the same time. The express package is identical. FedEx may take the wrong sample when it comes to pick up the goods. Find ways to completely eliminate problems and ensure that such problems do not occur again. Have colleagues discuss the new SOP for sending samples of hydraulic cartridge valves. Step 3: Determine the sample sending plan for the hydraulic cartridge valve test order. After discussion, implement the plan. Further consider what hidden dangers remain in the work and how to eliminate them. I think that's the benefit of a 3 step process. Not only did it solve the problem, but it also educated subordinates and allowed them to grow. To achieve the goal, the work must be implemented in place, and the specific tasks should be recorded in the task list, specifying the responsible person, completion criteria, and deadline. After that, continuous tracking will be conducted to ensure implementation and that problems and hidden dangers can be resolved. AAK hydraulic cartridge valve, targeting, tracking the process, and obtaining results. Many times, it is important not only to focus on "What to do", but also to focus on "How to do" and "Who to do". https://www.aakindustry.com/info- , detail/hydraulic-cartridge-valves-aak535

Algernon comes from Brazil and has been very successful in purchasing hydraulic cartridge valves from China. Unexpectedly, at the beginning of this year, he was annoyed by the urgent purchase of a batch of hydraulic directional control valves. Due to time constraints, the boss requested Algernon to find a hydraulic cartridge valve manufacturer to customize a hydraulic directional control valve, with a production time of only 45 days, but an accuracy of within 2μm. Algernon contacted several of his most trusted hydraulic cartridge valve manufacturers in Ningbo China. As there are not many manufacturers with the ability to customize non-standard hydraulic cartridge vales with high accuracy, the manufacturers that Algernon contacted were either not able to catch the delivery time, or meet the accuracy requirement. Algernon found on Google that AAK has published an article about producing the hydraulic directional control valve within 2μm accuracy, so he emailed us to ask if AAK can finish 30 non-standard hydraulic directional control valve samples within 45 days? After communication, we learned that he has a very tight time frame and high accuracy requirement that the other hydraulic cartridge valve manufactures in Ningbo were not able to meet. This is just the problem that AAK always like to challenge and solve. I told Algernon that AAK already has more than 5 customer cases about finishing 30 non-standard hydraulic directional control valve samples with 2μm accuracy within 45 days. Algernon paid the development fee the next day, and within 45 days, AAK sent out the samples. Last week, Algernon said that their equipment debugging was smooth, and they were confident in obtaining a batch order of the equipment. He asked me to patiently wait for the reorder of this non-standard hydraulic directional control valves. AAK hydraulic directional control valve samples can be finished efficiently, with accuracy controlled within 2μm. The key is that AAK has imported TSUGAMI CNC Precision Automatic Lathe from Japan, which provides us with confidence. 1. Turning and milling composite processing is the advantage of this equipment, which can complete most of the processing processes in one go, reducing the production cycle of tooling and fixtures, and reducing the processing time by more than 30% compared to conventional CNC Precision Automatic lathe. 2. The transformation of guide sleeve spindle and non guide sleeve spindle can be carried out, and the machining accuracy of the components can be ensured. 3. The clamping frequency is 40% less than other CNC Precision Automatic lathe, and there is a self review function in place during processing, which not only improves processing efficiency but also ensures that the processing accuracy of each valve seat is controlled within 2μm. AAK hydraulic directional control valve, fast processing, high precision, you can also give it a try!

At the beginning of last year, Lawrence sent an email to ask for help. He is a purchaser of a hydraulic equipment company in Italy and has cooperated with AAK for 2 or 3 years. Almost all of the orders are a small number of hydraulic check valves with high requirements. When encountering problems, he always asks for help from AAK, and AAK is also happy to help him. After several rounds of email communication, it turned out that the power unit for controlling the hydraulic lifting column produced by their company had a customer complaint 3 months after sales. Their engineers found a leak on the valve block of the power unit, that is, around the valve hole equipped with the hydraulic pilot operated check valve. It is preliminarily judged that the leakage should be caused by the wear of the seal of the hydraulic pilot operated check valve. However, after dismantling the hydraulic pilot operated check valve, it is found that the sealing ring is intact. After Lawrence communicated with the original manufacturer of hydraulic pilot operated check valve, they both thought that there should be no problem with the hydraulic pilot operated check valve or valve block, because the test data before shipping were qualified. The leakage problem should be caused by the wrong operation of the installation personnel of their company. Lawrence seemed to understand because it is true that the test result of the hydraulic pilot operated check valve originally shipped was OK. Lawrence asked their engineers to reinstall it. As a result, it worked normally and everyone thought the problem had been solved. But 3 months later, the same problem happened again, and the customer could not accept and requested to return goods. The boss was very angry and asked Lawrence and the engineer to completely solve the leakage problem of the hydraulic pilot operated check valve. This is why Lawrence emailed to AAK for help. AAK engineers analyzed according to the valve block integration diagram and the drawing of hydraulic pilot operated check valve provided by Lawrence. There is an assumption that the frequent vibration of the power unit of the hydraulic lifting column affects the stability of the installation of the hydraulic pilot check valve. Following this idea, it is found that the hole depth of the threaded socket integrated with the valve is not enough, which leads to the loosening of the jack position of the hydraulic pilot operated check valve. This problem can only be solved by adjusting the depth of the jack, increasing the thread torque of the hydraulic pilot operated check valve and increasing the bonding area between the valve and the hole. The next day I emailed Lawrence the idea of our engineer's. If we want to verify this idea, we can only make samples. One month later, AAK sent the redesigned hydraulic pilot operated check valve and integrated valve block to Lawrence. Last week, Lawrence sent an email saying that after the hydraulic pilot operated check valve and valve block redesigned by AAK were installed on the equipment, so far, the hydraulic lifting column has been used without abnormality. The customer was very satisfied that they finally solved the leakage problem of the hydraulic pilot operated check valve at one time. His boss also appreciated Lawrence for helping the company solve the after-sales problem. AAK hydraulic pilot operated check valve is cleverly designed to easily solve the leakage problem.

Last week, Kedma from Israel left a message on the hydraulic manifold manufacturer AAK website: 1. We need to customize a hydraulic manifold block, for each 2 opposing faces of the 6 faces of the manifold block, its accuracy must be the same. 2. This hydraulic manifold block is intended for military equipment. If it does not meet the requirements, please do not provide a quotation. I saw this message and did not reply directly. But instead, I asked Kedma, ‘You should have checked with many hydraulic manifold manufacturers, right? And most of these hydraulic manifold manufacturers gave no reply or said No.’ Kedma agreed with my guess and asked me how I found out. I told Kedma that most hydraulic manifold manufacturers in China are not confident, especially when it comes to military products, they are a bit scared. Moreover, Kedma has special requirements, and these hydraulic manifold manufacturers do not want to cause trouble, and some hydraulic manifold manufacturers do not have the ability to do so. Kedma seems to be interested in AAK and asked me how much time and cost it would take to customize this hydraulic manifold block, and how can AAK ensure that the accuracy of the 2 opposing faces of the hydraulic manifold block must be consistent? I said, before providing a quotation and development, let's first watch a video of how AAK processes hydraulic manifold blocks. From the video, it can be seen that the key points are the 3 steps: 1. The processed hydraulic manifold block should be properly positioned to ensure centering. 2. The processed hydraulic manifold block should be securely fixed to ensure no displacement 3. The 2 opposing faces of the hydraulic manifold block are processed and milled simultaneously. The double-sided milling machine is a perfect match for Kedma's special requirements for hydraulic manifold blocks. It is driven by the spindle and simultaneously drives 2 symmetrical milling cutters. At the same speed and milling depth, the surface roughness of the 2 opposing faces of the hydraulic manifold block is also synchronously controlled. The 2 symmetrical milling cutters are capable of cutting 360 degrees without dead angles in front and back, up and down, left and right. The processed hydraulic manifold blocks do not need to be flipped, avoiding secondary positioning errors. Most hydraulic manifold manufacturers process the hydraulic manifold blocks by one face to another, which not only has low efficiency and unstable accuracy, but also cannot achieve the same accuracy of hydraulic manifold blocks on 2 opposite sides. AAK hydraulic manifold blocks, processed on 2 opposite sides simultaneously, with no errors, you can also try it out.

Galeno is from Spain and has cooperated with AAK hydraulic valves for 5 years. Some time ago, he sent me an email asking us to design a hydraulic direct acting cartridge relief valve to replace the 3 HydraForce standard hydraulic cartridge relief valves in his system. After communication, we learned that their customer had customized a new equipment and was satisfied with their hydraulic power unit functions, but the customer found that the cost of the equipment had no advantage in the market. Because the hydraulic components used are all standard parts, there is little possibility of price reduction. Their engineers said that the only possibility is to use one hydraulic direct acting cartridge relief valve to realize the 3 functions of the 3 cartridge relief valves with different pressure controls in the system, and the system circuit is simplified. Galeno contacted HydraForce for customization, but HydraForce was not willing to develop this non-standard part due to small quantity. According to the schematic diagram of the hydraulic system provided by Galeno, and the drawings of 3 HydraForce standard parts, AAK engineers found the solution after discussion. The hydraulic direct acting cartridge relief valve redesigned by AAK can replace the original 3 valves without affecting its function. After 45 days, AAK sent 10 samples of hydraulic direct acting cartridge relief valves. 1 month after the samples of the hydraulic direct acting cartridge relief valve was sent, Galeno informed us by email that the equipment could work with AAK hydraulic direct acting cartridge relief valve, and its functions were not different from those original ones. The prototype has been sent to the customer. He said jokingly that everyone just needs to wait for a big order. The hydraulic direct acting cartridge relief valve designed by AAK, is arranged with an oil return hole at the level of the front end of the poppet valve spool, a thrust belt is arranged around the front end, and an oil hole is arranged on the poppet valve spool. There is a spring between the poppet valve spool and the pressure regulating screw plug in the valve body. The vertical position at the front end of the poppet valve spool corresponds to a cylindrical oil chamber, which is connected with the oil inlet. When the pressure oil enters from the oil inlet hole, if the thrust generated by the thrust ring is less than the set pressure of the spring, the poppet valve spool is closed. When the thrust generated by the system is greater than the constant pressure of the spring, the pressure oil pushes the thrust ring to open the poppet valve spool, and the pressure oil flows back to the oil tank through the oil return hole. No matter which pressure state is high, medium or low, the functions can be satisfied, and the hydraulic system is simplified. AAK hydraulic direct acting cartridge relief valve is adjustable for 3 pressures. You can also have a small try! https://www.aakindustry.com/info-detai , l/relief-valves-aak459

Erik compared more than 20 hydraulic pilot pressure control valve factories. No manufacturer can do the hydraulic pilot operated pressure control valves which can be used under high pressure above 450bar for more than one year. AAK hydraulic pilot operated pressure control valve passes the test at one time, and there is no abnormality after one year of use. Erik is from a German hydraulic equipment manufacturer. In the first half of last year, the company needed to purchase a special hydraulic pilot operated pressure control valve with a working pressure of more than 450 bar, a service life of more than one year and a durability of more than 2 million times. The boss realized that it was some difficult to purchase the hydraulic pilot operated pressure control valve this time, and asked Erik and his colleague to purchase at the same time. Whoever successfully purchased the hydraulic pilot operated pressure control valve first will be promoted and raised. Erik is full of energy and keeps looking for hydraulic pilot operated pressure control valve factories online and offline. He contacted more than 20 new suppliers, including AAK hydraulic valve. Most of the hydraulic pilot operated pressure control valve manufacturers replied that they need to be customized from the beginning of materials, and it takes 25 days to sample this special hydraulic pilot operated pressure control valve. Erik chose two factories to test the samples. A month later, Erik received the samples and asked the engineer to test them. The results failed, but the hydraulic pilot operated pressure control valve obtained by his colleague passed the first test, which made Erik very depressed. Fortunately, this is just in the test stage, the final effect depends on the test results of the hydraulic pilot operated pressure control valve one year later. Erik contacted AAK for the second time. He clearly informed that the samples of hydraulic pilot operated pressure control valves he selected in the first round failed. For the first time, he did not choose AAK because AAK needed 35 days. This time, he only asked AAK to make samples. Whether he can win or not, he can only count on AAK. Because the material selection and internal test of hydraulic pilot operated pressure control valves need time, Erik also understands the difficulties of making the samples. After 35 days, AAK sent 6 samples of hydraulic pilot operated pressure control valves. Last week, almost a year after the hydraulic pilot operated pressure control valve samples were sent, Erik sent an email to inform that AAK hydraulic pilot operated pressure control valve was the only sample that passed 2 million tests, and there was no abnormality after one year of use. Although his colleague's sample passed the early test, it could not withstand the high pressure above 450 bar for enough time, it leaked in less than a year. A few days ago, the boss praised Erik's purchasing ability at the company conference, and his dream of promotion and salary increase has also been realized. Erik was surprised that why AAK hydraulic pilot operated pressure control valve was normal after 1 year of use, while other manufacturers surrendered early? The core of this hydraulic pilot operated pressure control valve is material and heat treatment. AAK adopts 20CrNi2MoV high carburizing bearing steel imported from Germany, combined with carburizing pretreatment process, through secondary quenching + cryogenic treatment + low temperature tempering process, which is cooled to 650 ~ 700 ℃ and discharged after cooling to 450 ~ 500 ℃. The microhardness is 237 ~ 247 HV, and its wear resistance and contact fatigue performance are increased by more than 3 times. After heat treatment, the thermal stability and compressive strength of the material have long been far ahead. Most manufacturers may choose right materials, but they may not be able to do a good heat treatment. AAK hydraulic pilot operated pressure control valve, select and use good materials.

Logan has been a purchaser of a hydraulic company in the United States for several years, and the purchasing of hydraulic valves in China is also very smooth. But recently, a high-precision hydraulic relief valve order worth more than $30,000 wasted him a lot of time. The original hydraulic relief valve manufacturer made the samples twice, but was still not approved by the customer. His customer understood that the original manufacturer was unable to meet the requirement of 0.3mm finish size allowance, and asked him to change the hydraulic relief valve manufacturer to make samples for the third time. If the hydraulic relief valve sample for the third time still cannot be approved, the customer can only cancel the order. This order attracted the attention of his boss, who asked him to solve the problem and get the sample of hydraulic relief valve approved at one time within 20 days. Five days later, Logan consulted many hydraulic relief valve suppliers, and most manufacturers said that they could not meet the standard of 0.3mm finishing size allowance. Logan is a little worried. He looks for hydraulic relief valve manufacturers everywhere on the Internet. He left a message on our AAK website: how can we guarantee the finishing dimension allowance? All such messages are basically for difficult problems encountered in the purchase of hydraulic valves. After some communication, it is understood that the Logan was stuck on the sample approval process of the hydraulic relief valve order, and he has contacted many hydraulic relief valve manufacturers, but no solution has been obtained. I suggested Logan try our sample directly, and let the test data to speak for itself and this also saves time. Logan doesn't seem to have a choice but to expect that maybe AAK hydraulic relief valve can pass the test. A week later, AAK sent out 3 hydraulic relief valve samples. Logan did not dare to send the samples to the customer directly after receiving them, so he had to find a third party for testing before sending them to the customer. Without incident, the customer approved AAK hydraulic relief valve samples. His boss was also surprised that how a hydraulic relief valve manufacturer found by Logan this time can solve the problem so quickly at one time. The heat treatment process in the early stage is the first step of finishing the size allowance. Most hydraulic relief valve manufacturers adopt local quenching, so the heat treatment process of the workpiece is not easy to control and may be deformed. As early as 6 years ago, AAK adjusted local quenching to overall quenching. At the same time, vertical flow treatment must be required for the hoisting mode in the process of quenching and tempering, so as to minimize the influence of tissue stress and thermal stress on deformation during workpiece heat treatment, so as to meet the requirements of dimensional allowance for finishing. Logan cancelled the order with the original hydraulic relief valve manufacturer without hesitation and confirmed the order with AAK hydraulic valve in two rounds. Logan privately told us that his customers like the hydraulic relief valve manufacturers such as AAK very much. The customer pointed out that AAK should be as the priority supplier for future inquiry of hydraulic relief valves. His boss was also very satisfied with his ability to quickly solve problems this time, and put higher and higher expectations on him. AAK hydraulic relief valves, strictly controls the size allowance of finishing to ensure the accuracy of products.

This Monday, Arthur sent an email to purchase 1,600 hydraulic threaded cartridge valves at one time, which was a little unexpected. Arthur came from a hydraulic equipment manufacturing company in Italy. He met with us at the PTC exhibition in Shanghai 3 years ago. At that time, he communicated with us for about half an hour. Then there were several inquiries for hydraulic threaded cartridge valves and several trial orders for hydraulic threaded cartridge valves. Last October, he suddenly sent an email saying that he had a client in Ningbo who wanted to visit AAK hydraulic valve factory. We introduced in detail a series of production links from raw material inspection and warehousing to rough machining, finishing, process inspection, assembly of valve body and spool, testing, packaging, warehousing, marking and shipping of each part of hydraulic threaded cartridge valve. After the visit, Arthur's client said they were satisfied with the scale, equipment and management of AAK factory and left. I wondered if this was really Arthur's client. More than a month later after visiting the factory, Arthur said that his company has developed a new hydraulic equipment, which requires high-precision hydraulic threaded cartridge valve. AAK needs to quote and make samples for testing as before. AAK sent 16 samples of hydraulic threaded cartridge valves after 30 days. I still think that this one will be the same as that one year ago, no big waves. I didn't understand that I made the mistake of "I thought" until receiving the large order of 1,600 hydraulic threaded cartridge valves yesterday. Today, I learned by email that it was not his client who came to visit the factory last year, but his assistant who often stayed in China. Before the company developed this hydraulic equipment, his assistant ran to more than 30 hydraulic valve manufacturers in China, especially for this special hydraulic threaded cartridge valve. AAK hydraulic valve has its own advantages in equipment and extension of equipment and on-site detail management. In particular, the component testing room of AAK is constant temperature and humidity for 24 hours, which is very helpful for hydraulic threaded cartridge valves with high precision requirements. Because of the particularity of this hydraulic threaded cartridge valve, the accuracy inspection of each component should be completed in a specific environment. Some quality problems of the products of many hydraulic valve manufacturers are just due to the deviation of the test results caused by the instability of the test environment. In the view of many factories, this may be a small detail, but AAK has done extremely rigorous testing. His assistant has not found a second one in Ningbo who pays so much attention to detail. That's why Arthur chose AAK to produce this big order of hydraulic threaded cartridge valve. AAK hydraulic threaded cartridge valves, with much attention on details, high standard and high inspection. Welcome to try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-threaded-cartridge-valves- aak169
