Pozo is from Argentina, and left a message on AAK hydraulic cartridge valve website the day before yesterday: I saw a customer case that AAK hydraulic counterbalance valve has 1 additional function compared to its peers. We also have similar difficulties. Can AAK customize the hydraulic counterbalance valve according to our parameter requirements to meet our equipment requirements? After communication, it was learned that Pozo's lift experienced shaking and impact when the load was lowered, resulting in unstable system. Pozo contacted several hydraulic cartridge valve manufacturers in China but made no substantial progress. According to the dissected diagram of the hydraulic counterbalance valve sample he emailed, as well as the schematic diagram of the lift hydraulic system, it is very similar to the one customized by AAK for a Peruvian customer a while ago. The overflow area of the hydraulic counterbalance valve port undergoes a sudden change, which cannot timely buffer the pressure peak generated by load impact. I showed him a diagram of how AAK solves the overflow area of the hydraulic counterbalance valve port. Based on this, then to optimize the internal structure and external dimensions of the hydraulic counterbalance valve, it will match his hydraulic system. Pozo requested AAK to make samples of hydraulic counterbalance valve, and today we received his bank slip for the development fee. The optimization plan that we proposed to Pozo is as follows: 1. The hydraulic counterbalance valve sleeve is equipped with a transverse through hole to form the main hole section of the valve sleeve, a reducing hole section of the valve sleeve, and a valve sleeve flow groove connected to the fourth oil port on the outer wall of the valve sleeve. 2. In the main valve body of the AAK hydraulic counterbalance valve, there is a fixed first valve seat. The main valve spool slides and fits with the main valve body, dividing the inner chamber of the main valve body into the first and second chambers connected to the oil inlet, as well as the control chamber. The second chamber is equipped with a second valve seat and elastic components. 3. There are multiple U-shaped grooves along the axial direction on the circumferential surface of the main valve spool. The valve spool is located in the main hole section of the valve sleeve and can move left and right. On the left side of the second valve spool reducing section, there is a protrusion for opening and closing the valve seat transition hole section, and on the right side of the protrusion, there is a valve spool throttle hole. When the pressure oil enters, the valve spool begins to move left and gradually exposes various radial throttle holes. The flow area can be relaxed and increased, and the hydraulic counterbalance valve can timely buffer the pressure peak generated by load impact. After the plan is confirmed by Pozo, our sampling master can start working, and it is estimated to be another month of hard work. Come on, masters! I am also very happy today. AAK can provide help to others again, and at the same time, AAK has another new customer. With AAK hydraulic counterbalance valve, the equipment has no shaking or impact, and you can also give it a try!

Caspar is from Samhydraulik S.p.A. in Italy, mainly responsible for the purchasing of hydraulic valves. In March this year, Caspar requested AAK to sample 10 hydraulic pressure control valves by soonest. This sample order was quoted half a year ago. There must be a reason for him to be so anxious to place an order now. After several rounds of communication, it was learned that Caspar was cheated by the original hydraulic pressure control valve manufacturer. In the second half of last year, their company developed a new hydraulic power unit, which requires a high-pressure hydraulic pressure control valve, and the durability should reach more than 2 million times. Caspar contacted more than 10 hydraulic pressure control valve manufacturers. Most of them are able to produce the hydraulic pressure control valves with high pressure resistance and durability of more than 2 million times. Only AAK hydraulic valve and other 2 manufacturers have quoted prices. After receiving our quotation, Caspar said that the price of AAK hydraulic pressure control valve was about 20% higher than that of other manufacturers, and then there was no further news. Until today, 6 months later, he was anxious to ask AAK to make samples immediately. 6 months ago, Caspar selected another hydraulic pressure control valve manufacturer to make samples. 5 weeks later, their new hydraulic power unit was successfully tested and the equipment was expected to be popular. Caspar asked the original hydraulic pressure control valve manufacturer to hurry up to prepare materials, but the manufacturer wanted to raise the price by 40%. Because the valve spool material was hard, the cutting tools needed to be changed constantly, the production cost was increased, and the defective rate was also high. If without a price increase, the manufacturer refuses to produce the order. Caspar felt very helpless. The boss was very dissatisfied with such a hydraulic pressure control valve manufacturer who raised the price at the last moment, and asked Caspar to find a new manufacturer. Caspar suggested that AAK can make samples. If the original price of AAK hydraulic pressure control valve can be maintained, 20% of the cost will be saved. 1 month later, AAK sent 10 samples of hydraulic valve pressure control valves. 1 week later, Caspar informed that the test was passed and 1,000 samples need to be produced immediately. Caspar also wants to know why AAK hydraulic valve pressure control valve can maintain its original price in the same 6 months, while the other manufacturer needs to increase it by 40%. Most manufacturers of hydraulic pressure control valves do not pay attention to some details in the processing at the drawing stage, and only know after suffering in the sampling process. This hydraulic pressure control valve has high requirements, especially the reaming of valve spool hole is the key to the finished product. AAK does not need to constantly change the tools, because the ingenious use of cutting fluid in the cutting process can reduce the friction between the tool and the workpiece surface, reduce the chip, and reduce the cutting force and cutting temperature. This is a unique skill. AAK engineers with more than 20 years of production experience strictly control the process, and select the best Castrol cutting fluid in the world. With its high permeability and high adsorption efficiency, combined with the control of our engineers, not only the cost is saved, but also the tool wear is effectively reduced, and the surface quality of the workpiece is also high. AAK hydraulic pressure control valve is high-pressure resistant and durable for more than 2 million times.

Dolly is from a hydraulic equipment company in Peru. His boss thinks highly of him and plans to promote him to be purchasing manager, but a hydraulic cartridge relief valve stumped him. In the first half of last year, they sold a batch of hydraulic power units. 3 months later, the customer complained that the adjusting screw of the hydraulic cartridge relief valve had serious slippage, and the failure to adjust led to the strike of the equipment. The hydraulic cartridge relief valve manufacturer advised that this hydraulic cartridge relief valve benchmarks HydraForce, and the material is the same as HydraForce. The adjusting screw slipped after 3 months, which was caused by the high frequency of use. It can only be replaced with new ones. But it still slipped after 3 months. The customer was not satisfied, and the boss was also angry. He asked Dolly to replace the manufacturer of the hydraulic cartridge relief valve with a new one and ensure that it was safe for 1 year. Dolly became to be under great pressure. Dolly noticed AAK hydraulic valve website on Google and left a message: What is the root cause for the regulating screw of the hydraulic cartridge relief valve to slip in 3 months? As soon as I saw this message, I guessed that he had encountered a customer complaint. After communication, I learned that the original manufacturer had replaced the valves twice, the sliding problem was still not solved. This is the first time that I have met such a model, but AAK engineer said confidently that it would not be difficult to solve the problem and guarantee it for 1 year. After 30 days, AAK sent 30 hydraulic cartridge relief valves. Last week, Dolly sent an order for 960 hydraulic cartridge relief valves, specifically referring to AAK's hydraulic cartridge relief valve adjusting screw. More than 1 year later, there was no slippage, and the customer was satisfied. AAK hydraulic cartridge relief valve has been used at high frequency for 1 year without damage, mainly due to the following 3 aspects: 1. Special material selection: GCr15 high carbon chromium bearing steel is selected as the regulating screw of the hydraulic cartridge relief valve. After special heat treatment, its hardness and wear resistance are increased by 30%. Most hydraulic cartridge valve manufacturers do not pay attention to the regulating screw and select carbon steel. 2. Special heat treatment: the regulating screw is first heated to 810 ℃, isothermal annealed to 720 ℃, then air cooled, then oil quenched at 860 ℃, then carbonitriding at 830 ℃ for 3 hours, oil quenched, cryogenic treated at - 60 ℃ to - 70 ℃, finally tempered at 150 ℃ to 60 ℃, then air cooled, and finally the hardness can reach HRC67. General manufacturers cannot master the details of this heat treatment. Targeted geothermal treatment: the regulating screw is first heated to 810 ℃, isothermal annealed to 720 ℃, then air cooled, then oil quenched at 860 ℃, then carbonitriding at 830 ℃ for 3 hours, oil quenched, cryogenic treated at - 60 ℃ to - 70 ℃, finally tempered at 150 ℃ to 60 ℃, then air cooled, and finally the hardness can reach HRC67. General factories cannot master the details of this heat treatment. 3. Special testing: each adjusting screw is tested with a Rockwell hardness tester, and the hardness reaches the standard for 100%. Today, Dolly told me privately that his promotion to be a purchasing manager has been hold for more than a month. The boss officially promoted him today, and he became more and more energetic. AAK hydraulic cartridge relief valve, the details ignored by peers, we pay close attention strictly, you can try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak410

In last video, we introduced hydraulic cartridge valve manufacturer AAK, using a Hardinge CNC machine tool from the United States to produce a hydraulic pressure control valve cage within 2μm accuracy. Today, we will introduce a hydraulic directional control valve cage produced by a PSMT Turning and milling composite machining center, which is just next to the Hardinge CNC machine tool. The valve cage of the hydraulic directional control valve being processed is also controlled to an accuracy of within 2μm. Through the video, we can see that this PSMT turning and milling composite machining center is currently processing the hydraulic directional control valve cage. This equipment is equipped with 12 cutting tools, with B-axis and C-axis linkage. Turning and milling can be completed in one go, reducing the number of clamping times. One clamping, completing all the machining processes of the hydraulic directional control valve cage in one go, from drilling, boring, edge milling, to threading, its production efficiency is 40% higher than most machining centers. This process setting not only improves production efficiency, but also avoids human error. The device also has an online detection function. During the machining process of the hydraulic directional control valve cage, key data can be timely detected in place, ensuring that the accuracy of the hydraulic directional control valve cage is controlled within 2μm. AAK hydraulic directional control valve, production efficiency 40% higher than other hydraulic cartridge valve manufacturers in China, and accuracy within 2μm.

Levi is from a Canadian hydraulic equipment manufacturing company. He has purchased hydraulic needle valves from AAK for several years. We often have some discussion about hydraulic valves. In the second half of last year, they wanted to launch a new high-frequency four column hydraulic press, but the test was not successful. The hydraulic oil temperature is too high, resulting in unstable equipment running speed. Their engineers checked each circuit and found no problems. No abnormality was found in each hydraulic component, including the hydraulic needle valve. Levi contacted the original hydraulic component suppliers and did not receive any positive suggestions. A week passed without any progress, and the boss was worried. Levi thought of AAK. Although this batch of hydraulic needle valves was purchased from American manufacturer due to time constraint, some problems of the hydraulic needle valves in previous times were solved by AAK. AAK engineers found out the problem 1 day later according to the system schematic diagram, commissioning video and drawings of core hydraulic components provided by Levi. The probable reason is that the hydraulic needle valve has a problem. Levi doesn't believe it, because the hydraulic needle valves come from an American factory, they also tested the hydraulic needle valves separately, and there is no abnormality. AAK can redesign the hydraulic needle valve and send samples within 3 weeks. If AAK hydraulic needle valve can not solve the running speed problem of the equipment, we will return the trial order fee. Levi thinks there is no risk. Maybe this is also hope. 3 weeks later, we sent out the trial order of 10 hydraulic needle valves. Their engineers replaced the original hydraulic needle valves, and the four column hydraulic press was continuously tested for 48h. Although the oil temperature was also high, the speed of equipment operation was stable and the equipment operated normally. Levi was surprised that AAK newly designed hydraulic needle valve was more awesome than their American manufacturer. Their engineers admired AAK for finding and solving problems. Our customer in Belarus encountered similar problems last year, so our engineers quickly found the problem. The use frequency of this four column hydraulic press is twice as high as that of the normal one. The equipment works at high frequency for a short time, resulting in an increase in oil temperature and a decrease in oil viscosity. In this way, the flow of oil through the small hole of the hydraulic needle valve increases, which leads to a change in the originally set working speed and leads to the instability of the equipment. If the flow area of the orifice of the hydraulic needle valve is changed, the running speed of the equipment can be controlled by reducing the flow. Many times, most of the problems encountered have been solved by someone, and the curative effect is good. We only need to find this person or these people. The most stupid behavior of a person is not willing to learn or use ready-made experience. AAK is willing to solve every problem of hydraulic valves and has accumulated a large number of cases. Levi privately told me that the equipment running was smooth, the boss was in a good mood, and was confident that the equipment pre-sale would be hot, and the boss also looked him with new eyes. AAK hydraulic needle valves, Levi said that it is more powerful than that of the American manufacturer.

Recently, we launched a hydraulic cartridge proportional valve equivalent to HydraForce standard part SP12-20. It is a solenoid-operated, 2-way, normally closed,poppet-type, proportional, screw-in hydraulic cartridge valve, designed for low leakage blocking and load-holding applications. Last January in 2022, a hydraulic cartridge valve customer in Brazil found AAK when looking for a hydraulic cartridge valve manufacturer in China on google. He sent us a inquiry list for about 20 standard parts of HydraForce, one of them is SP12-20 but we did not have existing program for this valve at that time. The customer placed trial orders for other valves that AAK has existing stock, and continue to source for SP12-20 elsewhere. 6 months later, he informed us that the trial orders AAK delivered approved the testing, they have a very good performance, completely benchmarking the quality of HydraForce original ones. But he still had not found a reliable manufacturer for SP12-20 hydraulic cartridge proportional valve. He requested AAK to develop it. If the development is successful, he will place an annual order of 1,000 pcs. 60 days later, AAK delivered the 20 pcs of trial order. Last week, we received the annual order for 1,000 pcs of SP12-20 hydraulic cartridge proportional valve from him. Their company is very happy that the development is very successful, the quality is very good but the price is 30% lower than their previous hydraulic cartridge valve supplier in the USA.

In 2023, a disturbing journey has begun. Sometimes it is because the road ahead is unpredictable, sometimes it is because it is difficult to leave the starting place.   A few days ago, I needed to find strength and watched the trilogy of The Lord of the Rings again. After 20 years, I suddenly found that I had never really understood it before.   My favorite character is Gandalf. No matter how hopeless the situation is, as long as he appears, you will be relieved and ignite hope. However, Gandalf did not come in an all-powerful role. Unlike Frodo, Gandalf had no natural resistance to the Ring, but he understood and controlled his desire. Gandalf has all kinds of fairy friends, and he enjoys it when he is with the little people. Sometimes, regardless of his face, he tried to win the support of the powerful. After being rejected, he turned and left, never taking chances. He always tries to find the best game in the situation, even if the winning rate of that game is only 1%.   Perhaps Gandalf's strength comes from his belief in mission. He never entangled himself in the “so is the reality ", but committed himself to the "reality should be" without hesitation. How many people dare to go upstream in despair? How can the responsibility be easier than the lazy afternoon? People always make choices or decisions that are difficult to define. Facing the uncertain future, allocating limited resources requires wisdom, motivation and courage, and more importantly, motivation.   1. The first motivation is thinking, which is the brain; 2. The second power is the heart, which is the part of love; 3. The third driving force is the will, which is our hands and action. Gandalf in The Lord of the Rings uses his brain to make decisions. He tries to use all kinds of resources to think and act around the ultimate goal. Frodo's greatest talent is that he can resist the temptation of the Ring more than anyone else. Sam, by acting, felt that since he had made the right choice, he should stick to it. When Frodo doubted his mission at that time, he asked Sam: "What faith do we hold?" Sam replied: "There must be some beauty in this world that is worth fighting for."   Human excellence, like vines, grows like that. When nurtured, it thrives and reaches the blue sky. However, if you really believe in the tranquility of plants and the nourishment of fate, why would you go on a journey that is not consistent with probability? In this dark and unclear world, I need meaning, probability and temperature, as well as luck that I cherish.   Most people, first make a choice, then deduce the correct reason, and then give a meaningful explanation. How can I wait and see at the table of fate, whose life is not the only bet? Sam, Merry and Pippin in "The Lord of the Rings" do not take the initiative to choose. They are like drinking too much wine, throwing dice at random, and then hitting the road at 6.   Maybe each of us is a mouse of fate, and life itself is a single dice game. In such an external environment, maybe I have nowhere to escape. But I can still think like Sam: now that I have won the game, let me play it. What we need to do is not to weigh the advantages and disadvantages of A or B, but to never give up the chance to throw dice. In this life, it's time to play a game.   On the vast and boundless plain, Gandalf was alone, white robe, white horse, facing the spirit of death, he went upstream and raised his wooden staff. Gandalf knew that only human beings were their own saviors, and the only thing he could do was to let himself be present.   There are flowers and fruits everywhere, and life is full of beer, pipe and endless revelry. The Brandy River, the hole at the bottom of the bag, Gandalf's fireworks, the colored lights hanging on the tree in the party... The carefree people forget the time and wait for the arrival of a person in the dance. He drove the carriage full of fireworks and was about to light the whole starry sky. 2022 is passing by, which is really hard to say. Uncertainty is everywhere. The more uncertain we are, the more we know how to cherish the warmth and certainty of standing with "our own people". Winter will surely pass and spring will come. When the spring comes, let's cook wine and tea together and talk about the future with smile!   Everyone is waiting for a warm force. Everyone is waiting for a pair of hands. But perhaps more importantly, we should stretch out our hands to embrace the world, and every one of us. Don't worry, they are always behind you. Now, it's your turn to pass this warmth to every one of us. AAK hydraulic valve, be Gandalf in the cartridge valve manufacturers, delivers action, love, and warmth. https://www.aakindustry.com/info-de , tail/cartridge-valve-manufacturers-aak479

Half a year ago, David, an American customer, sent an inquiry to AAK about 500 pilot operated hydraulic relief valves. This hydraulic relief valve is difficult to process the inner hole. Our cost accounting department gave a reasonable price. 3 days later, David informed AAK that the price of the hydraulic relief valve was 16% higher than that of other manufacturers and he could only place the order with other hydraulic relief valve manufacturer. As far as I know, there are not many manufacturers who can make this hydraulic relief valve. The price provided by AAK this time should be very cost- effective. As David is our old customer, we never quote prices indiscriminately. I always believe that it is also a sign of dishonesty to quote prices indiscriminately. Last month, David asked again whether the hydraulic relief valve quoted last year could maintain its original price. I asked him curiously, hasn't this hydraulic relief valve placed an order yet? David truthfully told us that last time, the pilot operated hydraulic relief valves purchased in another manufacturer were reported by the users that the stability was poor and the valve was often stuck. They decided to get replacements. David contacted the original manufacturer of the hydraulic relief valves, but the manufacturer was unwilling to offer replacements. Because there were too many complaints, David did not dare to ask the original manufacturer to re produce, so he emailed AAK. David was very cautious this time. He specially sent us 5 samples of hydraulic relief valves from the original manufacturer. After receiving and checking, we found that the inner hole of the hydraulic relief valve has a taper, the processing size is not accurate, and the surface roughness Ra is as high as 1.6μm. The root cause of these problems is that the processing tool rotates improperly, which also shows that the original manufacturer is not good at processing this special inner hole. No wonder there are so many complaints. It is wise for David to change the factory. David was satisfied with our diagnosis of this hydraulic relief valve and asked us to make samples as soon as possible. 1 week later, AAK sent the samples of hydraulic relief valve, and David approved our samples at one time. They specially compared AAK hydraulic relief valves with that of the original manufacturer. Their engineers admired the inner hole processing of AAK, which not only has no taper, but also has more than twice the accuracy of the original manufacturer. For the special inner hole of this pilot hydraulic relief valve, AAK adopts CBN cubic boron nitride cutter from Sumitomo company of Japan to replace the conventional ceramic cutter. Most hydraulic relief valve manufacturers dare not use this cutter, which is not only costly, but also exquisite in operation. After the program is set, the tool completely avoids the taper of the inner hole. At the same time, for the machining of inner holes, we also customized the CBN boring cutter of integral cemented carbide steel, which can ensure the roughness value Ra below 0.8μm. Our technicians deliberately adjusted the cutting parameters to: n=400r/min, f=0.08mm/r, which improved the production efficiency and dimensional stability. AAK has never been stingy with the cost to ensure the processing quality. For the inner hole processing with high quality, AAK only uses the latest and most efficient cutting tools in the industry. AAK hydraulic relief valves most welcome customers with high quality. You are welcome to give it a try and be repaid with AAK unique skills. https://www.aakindustry.com/info-de , tail/hydraulic-relief-valves-aak249

Els is from South Africa, and operates hydraulic machinery business very well in the local market. Recently, she wanted to reduce the energy consumption of a high-pressure hydraulic power unit. The hydraulic pressure control valve in the original system, coupled with multiple changes in fluid direction, results in a small fluid path, resulting in significant energy loss and high energy consumption in the system. The original hydraulic pressure control valve manufacturer advised that the 350 bar high pressure is the root cause of high energy consumption and the valve is the standard part of HydraForce hydraulic pressure control valve. The manufacturer is not willing to change the program. Els was very helpless. Els found AAK hydraulic valves via Google search. She left a message on AAK website: Are you willing to improve the standard part of HydraForce hydraulic pressure control valve to meet the energy consumption needs of our equipment? Upon seeing this message, it is probably clear that other hydraulic cartridge valve manufacturers in China are unwilling or unable to optimize the standard part of HydraForce hydraulic pressure control valves. According to the hydraulic system and working conditions of the equipment she provided, the standard part of the HydraForce hydraulic pressure control valve is indeed not suitable for their equipment. If the original 90 ° guide flow is optimized to 180 ° direct flow, and the optimization is successful, the energy consumption can be reduced by at least 15%. Els paid a development fee of $2,000.00. After 45 days, AAK sent out 10 hydraulic pressure control valve samples. Yesterday, Els emailed us a PO for 500 hydraulic pressure control valves. The functions of AAK hydraulic pressure control valves meet their equipment requirements, and energy consumption has been reduced by 20%. There will be no problem that the equipment will sell well. AAK hydraulic pressure control valve is connected to the control of internal and external flow diversion, and together with the control of internal and external discharge flow, the original 90 ° guide flow is optimized to 180 ° direct flow. 1. The valve spool of AAK hydraulic pressure control valve is a tubular lifting type with a sliding control sleeve, exposing the radial hole in the valve spool and entering the open position, sealing the radial hole to enter the closed position. 2. The tubular lifting valve spool is connected to the threaded end, and the outer diameter of the valve spool extends to the radial orientation hole of the inner diameter. The hole faces forward from the inner side to the outer side at a 180 degree angle, making fluid flow smoother. 3. The control sleeve is connected to the spring wrapped around the tubular lifting valve spool, and there is an oil groove for aligning the control sleeve in the corresponding hole in the valve body. The control sleeve can slide along the length of the tubular lifting valve spool between the seat and the retaining ring. AAK hydraulic pressure control valve, reduces energy consumption, and is also durable. You can give it a try!

This week, we’d like to introduce a hydraulic directional cartridge valve equivalent to HydraForce EP20-S35. It is a screw-in, cartridge style, pilot to close hydraulic directional element. Last month, we received an inquiry from a new customer from the United States for a hydraulic directional element equivalent to HydraForce EP20- S35. After quoting, we were advised that AAK price is not competitive, and we have almost forgotten about this client. Unexpectedly, today, the customer got back to us again and placed a trial order for 10 pcs. After communication, we learned that the customer checked with many other hydraulic cartridge valve manufacturers in China, they either have no equivalent model, or the price is even higher than AAK. At the same time, his friend in the same industry also recommended AAK to him. All of these made him believe that AAK is the right choice. We are confident that this new American customer will become a long-term partner of AAK very soon.   AAK hydraulic directional element E-EP20-S35 two advantages: 1. The function and performance is equivalent to that of HydraForce EP20-S35 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-EP20-S35 hydraulic directional element: Max.

On Monday morning, I received an email from Whitney to order 2,000 hydraulic relief valves at one time. I am glad that Whitney's first order for the hydraulic relief valves to AAK was a big one. Whitney was introduced to AAK by Friedlich of Polar company, our old customer. The hydraulic relief valve she inquired about was similar to the hydraulic relief valve purchased by Polar company last time. Both of them were non-standard hydraulic relief valves. In October last year, Whitney's newly designed hydraulic equipment needed a hydraulic relief valve. According to the requirements of equipment working conditions, the durability of the hydraulic relief valve should reach more than 2 million times. Because the equipment time was very tight, the boss asked Whitney to get the samples of the hydraulic relief valve in place within 6 weeks. Whitney knows that for non-standard hydraulic relief valves, the quantity of trial order is small, the time is tight, and the requirements are high. Most manufacturers are not willing to do it, and they can't do it well. Sure enough, Whitney sent emails to more than 20 manufacturers of hydraulic relief valves back and forth. They either replied that there was no time or no reply at all. This wasted more than a week but even the manufacturer was not determined. Whitney was very worried. Friedlich in Polar company is Whitney's college classmate. After learning that Whitney had difficulties in purchasing hydraulic relief valves, Friedlich asked her to contact AAK, because AAK supplied them with 3 batches of hydraulic relief valves with durability of more than 2 million times in 2021. I received an e-mail from Whitney requesting that samples of the hydraulic relief valves be sent within 4 weeks for them to debug the equipment. 2 weeks later, I sent her the parcel tracking number. She was surprised that the non-standard hydraulic relief valve was sampled in only 2 weeks. I replied directly that most manufacturers could not get non-standard hydraulic relief valve samples with high requirements within 4 weeks. The reason why AAK can send it out in 2 weeks is that your hydraulic relief valve is similar to the one customized by Polar last time. We only need to modify a few dimension data in the program. A week later, Whitney informed that the new hydraulic equipment was successfully commissioned with AAK hydraulic relief valves. At present, the durability of the hydraulic relief valves is being tested. I am confident to say that there is no need for your engineers to test the durability. I guarantee that more than 2 million times. Polar has purchased 3 batches of hydraulic relief valves from AAK within 1 year, that is to say that it has long been a fact that the hydraulic relief valves with durability of more than 2million times. She also wanted to know why AAK hydraulic relief valve was so durable. I told her that it took more than 2 months and 3 times for AAK to make samples for Friedlich before and finally selected 3Cr3Mo3W2V hot work die steel. This steel can withstand huge mechanical stress in work. It not only has high hardness, strength, wear resistance and toughness, but also has good high temperature strength, thermal fatigue stability, thermal conductivity and corrosion resistance. At the same time, its high hardenability ensures that the whole section has consistent mechanical properties, so as to ensure that the hydraulic relief valve will not be impacted and eroded during the working process of the system, and achieve durable performance. AAK hydraulic relief valve, it is very common to be introduced to new customers by old customers.

Someone left a message on AAK hydraulic valve website: I saw that some hydraulic valve peers were imitating AAK articles and some hydraulic valve manufacturers were imitating AAK new products. He also attached a link to me. AAK colleagues asked me how to deal with these hydraulic valve peers? I think so, I do my hydraulic valves, I write my articles. AAK hydraulic valve has been introduced to the public online, and its peers want to follow the flow. Perhaps several inquiries and even several orders for AAK hydraulic valves were taken away by them. But I know one thing very well. They are all fake AAK hydraulic valves. Sooner or later, their hydraulic valves will have problems. This part of the orders robbed by peers may return to AAK hydraulic valve. On the contrary, these peers are still creating public praise for AAK hydraulic valve, because AAK hydraulic valve is authentic and its quality is benchmarked to international first-class brands. Those peers who counterfeit AAK hydraulic valve are making negative teaching materials for AAK hydraulic valve. The peers imitated the article of AAK hydraulic valve and let them to copy it. If someone can copy my 100 articles, I should make friends with him. Why? He adores me. Why not make friends. Many times, for the same thing, our mentality and cognition are different. For example, when you see half a bottle of water, there are two kinds of mentality. A said: Oh, there is only half a bottle of water. B said: Wow, there is still half a bottle of water. Hydraulic valve peers copy my articles, I prefer to write every day, I am such an optimistic attitude. All the people who imitate me and copy me are creating public praise and negative teaching materials for me. I am grateful to them. At the same time, the business of AAK hydraulic valve will be better and better. Peers are imitating AAK hydraulic valves, but the sales volume of AAK has not come down, which means that the imitation of peers has no impact on AAK hydraulic valves. Why do I care about the imitation of peers and take time to pay attention to this? It's absolutely unnecessary. I don't suggest that everything should be absolutely right and the secondary disasters also need to be considered. For example, there is a fly outside the window of the office. Dozens of us work here. In order not to let this fly fly in, we don't open the window all year round. It's certainly wrong not to open windows all year round. But now many people have this mentality and have this understanding. They always look at the world with a negative and pessimistic attitude. The pessimist is always right. What he says is right, but the optimists in this world often make money. My peers copied my articles to imitate AAK hydraulic valve, and even the product names. This is similar to a fly outside the window. In order to contain a rotten man, delaying or ruining the great hydraulic valve business, which puts the cart before the horse. AAK hydraulic valve always adheres to the right path, because the right path is not afraid of being far. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak247

I have been interested in hand strings since last year, turning them from wooden beads into a personal item, which is a particularly fulfilling experience. Especially with time, the plain and unremarkable bracelets formed a patina, shining brightly, as if with spirituality, and the interaction between people and things formed a response. People need to interact more with each other, and the main part of hydraulic cartridge valve manufacturer AAK is also people. Hydraulic cartridge valve manufacturer AAK in China needs to constantly communicate with new and old hydraulic cartridge valve customers all over the world. Form a mutually dependent, supportive, and harmonious cooperative relationship through communication. The 3 tips of communication of Hydraulic Cartridge valve manufacturer AAK: smile, listen and praise. Smiling is the vanguard, just because he brings a beautiful smiling face, it makes the other person feel good the first time, and a smile will make you gain friends. Because of smiling and praising, people feel the sincerity of hydraulic cartridge valve manufacturer AAK; Smiling and refuting, it makes people feel the goodwill of hydraulic cartridge valve manufacturer AAK; Smiling and refusing, made people understand the situation of hydraulic cartridge valve manufacturer AAK. Listening to the speaker fulfilled his desire to express himself. For a person with a sense of distress, it allows them to vent their accumulated grievances, which in turn tends to make them confidants. Hydraulic cartridge valve manufacturer AAK has added another friend. Praise is priceless, and words of praise can be happily accepted by the other party. By this point of communication, you have already done everything you can, and the rest depends on the other party's response. Just like I did with my hand skewers, once it's finished, put it there, let it rest for a while, hand it over to time, and let it form a perfect patina through the fermentation of time. Finally, when others help us, hydraulic cartridge valve manufacturer AAK needs to say thank you. But when saying 'thank you', adding the other person's address or name after 'thank you' will make the other person feel more sincere and friendly than just saying 'thank you'. Because 'thank you' refers generally, while 'thank you + name' refers specifically. Adding the other party's name after "thank you" would be more appropriate if you could explain the reason for your gratitude and your true feelings. For ordinary people, "technique" is more important than "Tao", ability is more important than cognition, and doing what is at hand is more important than paying attention to the world situation. For hydraulic cartridge valve manufacturer AAK, customer trust is more important than inquiry. The 3 tips of communication is the first step to gaining customer favor. Hydraulic cartridge valve manufacturer AAK in China, focuses on manufacturing quality and trust.

AAK hydraulic manifold design runs through the whole process of design, manufacturing, use, maintenance and innovation. With such a five-level thinking, there is no second such hydraulic manifold manufacturer in Ningbo. A good hydraulic manifold design cannot be separated from manufacturing. The more an excellent hydraulic manifold engineer knows about hydraulic manifold manufacturing, the more helpful it is to improve the design level. The design of hydraulic manifold is inseparable from experience. Of course, professional experience can be learned from books, but it is difficult to leave a deep impression in your mind if you do not output it. It is not easy to absorb the experience of others without a foundation. AAK often receives some hydraulic manifold drawings that cannot be directly processed and assembled according to the drawings. It is common to find problems during drawing review and process. There are many reasons, such as the standardization of the drafter, the level of the reviewer, especially whether the designer has a deep understanding of the hydraulic manifold manufacturing process. AAK hydraulic manifold designer must be able to analyze the whole manufacturing process of a hydraulic manifold drawing designed by himself. If a hydraulic manifold engineer only knows casting, forging, turning, tongs, milling, planing, grinding and drilling, that is not enough. He must subdivide them. For example, how to divide the mold during casting, how to place the gate and riser, and what kind of casting defects may occur; For another example, the cutting process should be able to be visualized in your mind. How many knives are used in total, what rotation speed, feed rate, should be selected etc., and even the shape and color of the chips, as well as the sequence of each process. It does not mean that those engaged in hydraulic manifold design must be able to play with lathes and milling machines. Instead, they should know the characteristics of these operations and take them into full consideration in the design. Such hydraulic manifold design can settle down. In AAK, these are not enough, because technicians with more than 10 years of service need to have more mature detailed plans. The only solution is to read more books, communicate with old technicians and stay in the production workshop. The hydraulic manifold engineer should understand the interrelationship between the transmission and devices of the whole machine, and the interrelationship of each part. After understanding these, the drawing can be drawn, and the drawing can have clear dimensional matching requirements and geometric tolerance constraints. Instead of simply noting the machining accuracy on the drawing, but cannot be realized in production. If the designed hydraulic manifold can improve the added value of the equipment, optimize the function, improve the performance and improve the stability, so as to meet the high-end customers. The design made by a wordy person is a bit wordy, and the design made by a stingy person is a bit stingy. The hydraulic manifold made by an irresponsible person is just as irresponsible as that person's virtue. What others have summed up is usually the result of painstaking efforts. If we learn from problems, we can absorb the experience of our predecessors by imitating and thinking more. AAK hydraulic manifold engineer will not say such a stupid answer as "just ensure the concentricity", but the method to ensure the concentricity, and even point out the mistakes of the predecessors. At this time, the problems considered by AAK hydraulic manifold engineers need to be raised to a higher level, because the design serves "use", such as hydraulic manifold efficiency, energy consumption, stability and service life. If the hydraulic manifold design is not conducive to use, there will be complaints. The use is also inseparable from maintenance. The hydraulic manifold design cannot ignore the convenience of maintenance. Some large-scale hydraulic equipment is maintained only once or twice a year, and the equipment cannot be broken up every time. Otherwise, the eighteen kinds of weapons for the jack and crowbar of the travelling crane and forklift are not enough, the loss resulted from shutdown has exceeded the value of the hydraulic manifold itself. Hydraulic manifold design should not only stand on the basis of manufacturing, but also have innovation, and must learn to inherit. The innovation of AAK hydraulic manifold means that each hydraulic valve is reassembled into a new hydraulic manifold, or some new elements are added to the old hydraulic manifolds. New things are all born from negation in affirmation, and affirmation in negation. Innovation is like seasoning. With such a little seasoning, the food tastes more delicious. If you can have your own design concept and style, it is different. In this way, the hydraulic manifold has a unique soul. A truly hydraulic manifold engineer needs at least 10 years, or even more than 15 years of hard work. AAK hydraulic manifolds, engineers use design, manufacturing, use, maintenance and innovation to define the design of hydraulic manifolds. It may not be possible to find a second hydraulic manifold manufacturer with such a five- level thinking. https://www.aakindustry.com/info- , detail/hydraulic-manifold-aak246
