Daniel is a purchaser of Liebherr branch in Germany. He is responsible for the procurement of hydraulic components. He has done an excellent job some time ago and has been praised by his supervisor for many times. Before the shopping season, he wanted to relax and planned to go on vacation with his family next week. A phone call from the boss disrupted all his plans. A major dealer in Sweden asked for help for a excavator produced by their company within 1 week . His engineer came to the user for routine maintenance and found that there was oil leakage in the hydraulic system. After pressure test, it was found that there was oil leakage in the hydraulic check valve, and 12 excavators had such faults. Daniel hurriedly contacted the American supplier for this hydraulic check valve, and got the reply that it was too cold in Sweden at this time. For such high-frequency operation, even if the hydraulic check valve was replaced, it was estimated that the hydraulic check valve would still leak oil 1 week later. Unless more low temperature resistant sealing rings are used, this will take time to test, but the finishing time is to be determined. Daniel was so helpless, he had to find a new hydraulic valve supplier. Daniel asked several local hydraulic valve manufacturers. They either didn't have time to produce or require over 50pcs MOQ. After knowing these situations, the supervisor asked Daniel to give the dealer a plan that can be implemented within 10 days. Daniel had to cancel the vacation. Daniel thought of AAK HYDRUALIC VALVE who he had contacted for inquiry before. He emailed us to ask whether we can produce the hydraulic check valve for the excavator, which needs to be resistant to low temperature. According to the drawings and working conditions provided by him, we advised that it takes 20 days to customize. All our existing hydraulic check valves are not close to this size. Daniel reiterated the hydraulic check valve needs to be low temperature resistant, and frankly told us what they are currently experiencing. I answered directly that the core lies in the low temperature resistant sealing ring. Daniel felt that maybe AAK could solve this problem. After 18 days, we sent a sample of hydraulic check valve. The test results proved Daniel's feeling. The parameters passed the test and there was no oil leakage at low temperature. The order for 12 hydraulic check valves was also easily confirmed. Daniel's hanging heart can finally be put down. Daniel asked why American hydraulic valve manufacturer needs time "to be determined" to test, and we solved it in 18 days. Why German hydraulic valve manufacturer is unwilling to do this small quantities, but it is OK for AAK hydraulic valve. At the same time, the price of AAK hydraulic valve is cheaper than that made in Germany and that made in the United States. The zero leakage hydraulic valve not only has strict requirements on accuracy, but also strict requirements for the sealing ring due to different media or different scenarios. The sealing ring not only needs to be sealed, but also needs to automatically improve its sealing effect with the increase of the pressure of the hydraulic oil. It also needs not to leak under the harsh working environment such as low temperature or high temperature. 1 year ago, a Russian customer of AAK hydraulic valve put forward the requirement of low temperature resistance. We spent 6 months, experienced 3 failures and 6 seal ring material tests, and innovated a seal ring polymerized with polyurethane elastomer and special rubber from the perspective of friction coefficient. Its low temperature critical point is - 45℃, and its wear resistance, oil resistance, fatigue resistance and vibration resistance can meet high-frequency operation. It was mass produced 1 year ago. AAK delivered 12 hydraulic check valves to his dealer. After all installation and commissioning, they worked continuously for 2 weeks without abnormalities. The Swedish dealer was very satisfied with the high standard after-sales service provided by Liebherr branch. Daniel was very happy. His supervisor gave him special permission to spend more days with his family. AAK zero leakage hydraulic check valve was delivered to Liebherr. You can feel at ease to have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-check-valve-aak117

In July this year, Bowen, an Australian customer, visited 5 hydraulic valve factories before and after, and made samples of hydraulic relief valve with ±1μm inner hole for 3 times, but none of them reached the accuracy requirements. AAK sent samples and met the standard for the 1st time, Bowen finally chose to cooperate with AAK.   The inner hole accuracy is not enough, which is mainly caused by the different built-in equipment of honing machines equipped by many hydraulic valve manufacturers. Conventional honing machines use diamond reamers., Because the main cutting part of the diamond reamer is at the tool head, the tool head wears quickly. After the head is worn, it is very easy to cause the size of the hole bottom to be small, resulting in the poor cylindricity of the whole hole and affecting the accuracy. This is the key to the 5% accuracy error. Many hydraulic valve manufacturers are not aware of this key point.   Bowen, a purchaser from a hydraulic valve company in Australia, has an inquiry for a special hydraulic relief valve, and the inner hole accuracy must be controlled within 1μm. Bowen checked with the original hydraulic valve supplier, and got reply that only the hydraulic valve manufacturer equipped with high-precision honing machine is able to make the hydraulic relief valve with 1μm inner hole accuracy. According to the equipment configuration, Bowen has contacted with more than 10 hydraulic valve manufacturers, determined to visit 5 hydraulic valve manufacturers, and asked 3 powerful factories to sample the hydraulic relief valve. After testing and comparing the samples received from these 3 hydraulic valve factories, all failed to meet the standard. Bowen asked the manufacturer with the highest accuracy to continue to improve the proofing, and there is still ±0.1μm gap. The factory gave up and introduced AAK HYDRAULIC VALVE to him, maybe AAK can do the hydraulic relief valve with ±0.1μm inner hole accuracy.   According to his hydraulic relief valve drawing, we advised that we can send 1pc hydraulic relief valve quality sample after 10 days. 5 days after AAK successfully sent the hydraulic relief valve sample, Bowen informed that the accuracy met the standard. He wanted to know why so many hydraulic valve manufacturers could not achieve ±1μm inner hole hydraulic relief valve, even if the hydraulic valve manufacturers promised to do so and they also have high precision honing machines, but several proofing did not meet the standard. How did AAK hydraulic valve achieve it?   Honing machine is really helpful for the machining of high precision inner hole. Due to different equipment configuration, not every hydraulic valve manufacturer can produce the hydraulic relief valve with ±1μm inner hole accuracy. Different from conventional hydraulic valve manufacturers, AAK adopts sintered diamond tools, equipped with 15 tool position tool magazine and automatic tool change mechanism, which can automatically change tools and add deburring tools. At the same time, it has XY axis worktable, which can automatically change the hole for porous work pieces. At the same time, we have installed an online measurement system in the machine tool to automatically detect the initial diameter of the hole. The system also detects the hole distance, which can automatically alarm abnormalities and 100% eliminate human errors. Bowen's doubts are completely eliminated and asked us to do preparation for material. After he confirms the order with the customer, he will start placing order for this hydraulic overflow valve.   The peers can not guarantee high precision even with the same equipment, but AAK hydraulic valve has always been the leader in precision. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak116

In March this year, the sales manager of Caterpillar received a phone call from a Spanish customer complaining that several excavators produced by their company had small start-up faults. The repairman judged that the hydraulic system leaked oil, which should be caused by the leakage of the hydraulic check valve. The customer asked them to replace the hydraulic check valve as soon as possible. This customer accounts for 40% of Caterpillar's sales. Although it has passed the maintenance period, they must help the customer solve the problem. The original hydraulic valve supplier said that for the hydraulic check valve under this working condition, there can only be no leakage for 2-12 months. In extreme cases, it may be less than 2 months. The customer was disappointed with such a maintenance plan. The boss asked Mark, the purchasing manager, to find a solution satisfying the customer. Mark contacted more than 10 hydraulic valve manufacturers, but did not get a satisfactory reply. He boss urged him to make a new plan twice a day. Mark thought of AAK HYDRAULIC VALVE he had contacted before. Maybe AAK can do some help. He firstly asked us why so many hydraulic valve manufacturers can't achieve 0 leakage for more than 12 months for this style of hydraulic check valve? The hydraulic check valves often use steel ball or metal cone slide valve to contact and compress with the orifice of metal valve seat under the action of spring and fluid pressure to prevent the reverse flow of liquid, but it is difficult to achieve absolute seamless butt joint in the cutting of metal contact surface. Especially under the special working condition of this customer, it is more difficult to avoid leakage. This hydraulic valve manufacturer who has insured for 2 months is already great. Mark thought that AAK HYDRAULIC VALVE could not produce a hydraulic check valve with 0 leakage for more than 1 year, and asked how long we could insure at most. AAK can produce hydraulic check valve with 0 leakage for more than 12 months. If there is no leakage within 1 month, and if subsequent maintenance is in place, the hydraulic check valve can be 0 leakage for 24 months. Mark was surprised at our reply and thought we were joking. Let's talk about it with facts: AAK will send the hydraulic check valve samples within 20 days, you test the hydraulic check valve first, and we will then discuss it after the test. After 15 days, AAK sent the hydraulic check valve samples to Caterpillar. Their engineers conducted internal test first, and there were no abnormalities in many tests. Their after-sales personnel took the samples directly to the customer's construction site for on-site installation and commissioning. It worked continuously for 12 hours, and everything was still normal. The customer was very satisfied with Caterpillar's after-sales service. The boss was also very happy and asked Mark to hurry up to purchase. ark was curious how AAK achieved the hydraulic check valve with 0 leakage for more than 12 months? After receiving the drawings, AAK fine tuned the structure of the hydraulic check valve in the original design without adopting the traditional sealing design. A special soft sealing ring is installed between the outside of the boss of the valve seat and the end face of the valve spool. At the same time, the inner diameter of the soft seal ring is less than the diameter of the boss, rather than the traditional diameter more than that of the boss. When the hydraulic check valve is closed, the soft sealing ring will deform under the action of hydraulic pressure and compress the contact sealing surface between the metal valve spool and the metal valve seat to achieve 100% sealing and ensure 0 leakage. Last week, Mark sent us an inquiry for a new hydraulic valve. Incidentally, he said that since the Spanish customer installed their excavator with AAK hydraulic check valve, everything is normal. The customer has been purchasing other styles of excavators from his company. The boss is more and more appreciative of him now, and assigned all important purchases to him. AAK hydraulic check valve, zero leakage, pay attention to, welcome to have a small try if you need a new and top hydraulic valve manufacturer in Ningbo. https://www.aakindustry.com/info-detail/hy , draulic-check-valve-aak115

Recently, when chatting with several brother customers Felix and Carson, they asked me why the same model of hydraulic valve spool, AAK has higher precision and stronger sensitivity than its peers. This is a good question. I smiled and said: you may not have a comprehensive understanding of AAK hydraulic valve. For all types of hydraulic valve spools, AAK is subject to strict quality control. Under the condition of ensuring that the spool is suitable for the service conditions, we will select the most appropriate tool steel (40Cr, Cr12MoV, 12CrNi3A, 18crniwa and GCr15, etc.) according to the customer's parameter requirements and service scenarios. 6 major processing processes and 6 major parameters are used. This technology has led the industry, we are not satisfied with these static data, but also need dynamic spool. Since the valve spool needs to move in the valve body, the clearance between the valve spool and the valve body should not only ensure good sealing, but also ensure small movement resistance. Therefore, the matching clearance between the valve spool and the valve body is the top priority affecting the use of the valve spool. The following are the tolerances and matching clearance dimensions of the valve spool and the valve body produced in large quantities by AAK in the actual production process: Diameter Valve body tolerance Spool tolerance Minimum clearance Maximum clearance 6mm ±0.006mm ±0.004mm 0.0025mm 0.0125mm >6-12mm ±0.0075mm ±0.005mm 0.0050mm 0.0175mm >12-20mm ±0.01mm ±0.006mm 0.0050mm 0.0233mm >20-25mm ±0.0125mm ±0.0075mm 0.0125mm 0.0325mm When the reciprocating or rotary valve body is matched with the valve spool, we AAK generally use the minimum clearance, but the specific processing parameters should also be determined according to the customer's parameter requirements and use scenarios, so as to ensure that the hydraulic valve does not have any leakage, valve stuck and other unexpected working conditions. During the processing and manufacturing of valve spool, AAK also strictly considers the following aspects, and will check and test each valve spool when necessary, so as to ensure the high quality and reliability of valve spool. 1. Hydraulic power on hydraulic spool 2. Pressure and flow characteristics of hydraulic valve spool 3. Flow coefficient of hydraulic valve spool 4. Leakage of hydraulic valve spool 5. Stability of hydraulic valve spool 6. Vibration of hydraulic valve spool 7. Cavitation of hydraulic valve spool After listening, they admired AAK's rigid attitude and trusted the quality of AAK hydraulic valve more. Using AAK hydraulic valve is reassuring, so AAK has always been their preferred hydraulic valve supplier in China. AAK hydraulic valve sticks to itself and high quality control.

Recently, an IP from Germany left a message on the website of hydraulic cartridge valve manufacturer AAK: Can AAK process a hydraulic cartridge valve with the surface finish of the valve cage controlled within Ra0.2μm and with a dimensional accuracy tolerance within 0.5μm? I was a little pleasantly surprised to see this message because: 1. There are not many inquiries from German customers regarding hydraulic cartridge valves, although hydraulic cartridge valve manufacturer AAK has supplied more than 30 countries, this should be the third German customer's inquiry. 2. Not many customers seem to have special requirements for the surface finish of hydraulic cartridge valve cage. After 3 rounds of communication, I learned that Frank is a procurement engineer for hydraulic equipment company. Currently, he is in the trial stage to purchase from hydraulic cartridge valve manufacturers in China and is not very satisfied with the details of Chinese hydraulic cartridge valve manufacturers. Frank consulted 6 hydraulic cartridge valve manufacturers in China, but none of them was unable to guarantee his requirements on the valve cage. The order that Frank tried is a standard part of SUN hydraulic cartridge valves, but the requirements are higher than SUN's. AAK re- optimized the production process and equipped specialized equipment to ensure Frank's requirements for hydraulic cartridge valve cages. At this point, some of our old equipment, old technicians, are put to use. After 20 days, 30 hydraulic cartridge valves were sent out. 1 week after receiving the samples, Frank recognized the hydraulic cartridge valve cage processed by AAK, which met his requirements. We use a TOYODA cylindrical grinder from Japan to process the valve cage for this model. Although this grinder has been in AAK for 10 years and has a somewhat shabby appearance, it is the treasure of our veteran technicians, and we optimize the equipment every 2 years. Its stable grinding accuracy is the biggest advantage, not only high accuracy, but also stability, especially low vibration bed and high-precision feed mechanism, combined with specialized cutting fluid. The machined hydraulic cartridge valve cage has a clear contour and a surface finish of within Ra0.2μm, the dimensional accuracy tolerance is within 0.5μm. Why can the hydraulic cartridge valves provided by AAK meet the requirements of the German customer, while other 6 Chinese hydraulic cartridge valve manufacturers are uncertain? Because: 1. AAK adopts equipment from the Japanese military industry and also upgrades local functions. I don't know which hydraulic cartridge valve manufacturers in Ningbo often have these actions. 2. The experienced technician from hydraulic cartridge valve manufacturer AAK has over 30 years of industry experience. 3. For hydraulic cartridge valves with special requirements, AAK has the ability to re optimize production processes and pay attention to details. AAK hydraulic cartridge valves, meets special requirements, and German customers are purchasing it. You can also try it out.

Tony is a purchasing manager of Italian Casappa company, mainly responsible for the purchasing of hydraulic pump components. Last October, Casappa developed a new hydraulic pump and planned to promote this new product at this year's exhibition. During the debugging, the output pressure of the hydraulic pump can not be established several times, which is a little troublesome, because the owner has sent all the invitations to the exhibition to the customers and grandly introduced the functions of this hydraulic pump. The R & D personnel checked and tested each component one by one. It is basically certain that it is caused by the instability of the pilot operated pressure control valve. The technical team dissected the pilot pressure control valve and found local friction marks on one side of the hole wall of the valve body. The diagnosis conclusion is that the main valve spool is stuck, which should be caused by the concentricity difference between the hole of the main valve body and the hole of the pilot pressure control valve body. The owner asked Tony to re purchase the pilot pressure control valve that meets the technical requirements, which must be solved within 25 days, otherwise he will leave because the exhibition is too important. Tony contacted the original hydraulic valve manufacturer and got a reply that due to equipment, he could not produce high-precision pilot pressure control valves with the exactly same concentricity. At the same time, he contacted a number of hydraulic valve suppliers and they basically replied that they could not do such a high precision pilot operated pressure control valve, which made Tony almost collapse. When Tony searched the hydraulic valve suppliers in Google, he found AAK HYDRAULIC VALVE. The details page of the hydraulic valve on AAK website made Tony feel that maybe AAK could have a try. He emailed us firstly to ask whether the concentricity of the pilot operated pressure control valve could be consistent. We need the detailed drawings, working conditions and parameters of his whole hydraulic pump to judge. After receiving all information from him, AAK technical team pondered the whole afternoon, with more than 95% confidence, and it would take 15-20 days to complete it. Tony said he was happy and uneasy. He was happy that some hydraulic valve manufacturer could try this high-precision pilot operated pressure control valve and has a high probability of success. He was uneasy that if AAK HYDRAULIC VALVE did not succeed in proofing, the time would be wasted. We understand his concern. We told him that the reason why we are not sure for 100% is that there is a data that can't be determined. If AAK HYDRAULIC VALVE failed in sampling, then he should not waste time in Ningbo area. We suggest that he also find a hydraulic valve supplier in Europe, so as to sample with AAK at the same time. 2 weeks later, we sent a sample of the pilot operated pressure control valve. 4 days later, Tony sent an email excitedly informing us that the pressure of the hydraulic pump was completely normal after using the pilot operated pressure control valve with the same concentricity from AAK. The owner was very happy that the exhibition would not be affected. 5 days later, Tony sent another email to inform us that the pilot operated pressure control valve provided by a well-known hydraulic valve company in Germany had also been successfully tested. AAK took 15 days to proofing, and the German hydraulic valve manufacturer took 25 days. At the same time, the price of AAK hydraulic valve is 10-15% cheaper than that of German hydraulic valve. He was surprised why AAK took less time to proofing and the price was cheap, but the quality of the hydraulic valve was benchmarked with the well-known brand in Germany. AAK has made the most typical improvement on the equipment. On the high- precision machine tool imported from Switzerland, it adopts high-speed interpolation technology to realize continuous feeding with small program segments, so as to make the control unit of the machine tool more refined. At the same time, the high-resolution position detection device is used to improve the position detection accuracy, and the position servo system adopts feedforward control and nonlinear control methods, plus with the most experienced engineers to test the accuracy of each process, so as to ensure the consistency of the concentricity of the pilot operated pressure control valve. Tony admires our innovation in equipment, especially our quality benchmarking the German brand. After some time, he privately informed me that the exhibition was a great success, and the owner was in a great mood. Tony was not only praised by the owner, but also upgraded to the general manager of purchasing dept. AAK pilot operated pressure control valve has become the best choice for Casappa. The customer purchased from AAK said that AAK pilot operated pressure control valve is benchmarked with the German brand. AAK hydraulic valve has no leakage, 3 of 500 Global Top Enterprises in Use.

A few days ago, a customer from India asked me to follow his process to develop an integrated hydraulic cartridge valve. I provided our technical solution, but he requested to follow his approach and emphasized that the customer is Party A, and as the supplier of the integrated hydraulic cartridge valve, Party B needs to cooperate unconditionally with Party A. I don't quite agree. I think there are no first party and second party in business, only both parties. Perhaps the vast majority of integrated hydraulic cartridge valve manufacturers have become accustomed to Party B, and in their thinking, there is always a psychological state of Party B. For example, for this integrated hydraulic cartridge valve order, I want to ask for an order from the customer. I want to sell the integrated hydraulic cartridge valve to someone else, as if I want to appeal to the customer. In the process of interacting with the customer, it appears to be a weak position. Think about it, a weak person's psychology, a weak person's image, how does it feel to interact with others? In fact, the other party will not sympathize with you, but instead, they will consider themselves as the first party. This thinking of the second party is not conducive to the integrated hydraulic cartridge valve manufacturer, and in fact, it is not conducive to the customers of integrated hydraulic cartridge valves. Previously, a client from the United States asked me, 'What is the relationship between AAK and him?'? My answer is: relationship between the teacher and the students, he was a bit surprised. Afterwards, he appreciated my definition very much. So what is the psychological state of teachers and students? Teachers must love and help students. For example, AAK integrated hydraulic cartridge valves are very willing to help target customers. From the inquiry and development stages, we have been thinking about customers. Teachers do not mean to be domineering and superior. What is a teacher? He hopes that students will learn well, do well, and have compassion. From the perspective of professional knowledge, students should lack some. In the process of interacting with clients, we treat them as students and ourselves as teachers. This kind of communication is relatively selfless. In general, integrated hydraulic cartridge valve buyers are not as professional as manufacturers. Integrated hydraulic cartridge valve manufacturers have a richer knowledge base in terms of manufacturing quality, process hazards, actual customer cases, and some technical details. Therefore, AAK is capable and willing to help customers solve their problems with integrated hydraulic cartridge valves. So, think about it. If we interact with customers in this way, we are helping them, not seeking them. With this guiding ideology and psychological state, the entire interaction is benign and beneficial to both parties. With this positional relationship between teachers and students, manufacturers of integrated hydraulic cartridge valves often provide many constructive solutions. This mindset has changed, actions have also changed, and of course, the results have also been better. AAK integrated hydraulic cartridge valve, without Party A and Party B, only both parties AAK HYDRAULIC VALVES (607) 2023-06-17 https://www.aakindustry.com/info , -detail/hydraulic-cartridge-valve- manufacturer , s-aak607

Halian, from Sweden, has been engaged in the procurement of hydraulic components for 5 years. She began to purchase hydraulic cartridge valves from Ningbo last year, and was upset by the first purchase for a hydraulic cartridge relief valve. At the beginning of last year, their hydraulic power unit failed due to the blockage of the hydraulic cartridge relief valve she purchased from Ningbo. The original hydraulic cartridge relief valve manufacturer reported that the hydraulic oil was not clean, but after replacement, the old problem occurred again in 5 months. Halian thought that the manufacturing quality of the original hydraulic cartridge relief valve was not up to standard, so she contacted a new hydraulic cartridge relief valve manufacturer. Halian found AAK in B2B and left a message: Can AAK solve the problem of hydraulic cartridge relief valve blockage? After communication, it was learned that the hydraulic cartridge relief valve she purchased from the cartridge valve manufacturer in Ningbo was easily blocked. According to the hydraulic cartridge relief valve samples from the original factory, there are damping holes, and there are elongated holes in the valve body, which are objectively easy to block. Can we remove damping holes and elongated holes? According to this idea, we fed back the plan to Halian. After 40 days, AAK sent 20 samples of hydraulic cartridge relief valves. Last week, Halian informed us via email that AAK hydraulic cartridge relief valve was installed on the equipment, and it has been 8 months since then. There is no blockage and no customer complaint. AAK hydraulic cartridge relief valve removes the damping hole and slender hole in the original structure, increases the flow area, improves the flow passage port, and uses conical spring. Such hydraulic cartridge relief valve has 3 advantages: stable opening, short unloading time and small power loss. 1. AAK hydraulic cartridge relief valve seat is a cylinder with one end open and one end closed, and the open end has external thread, and the closed end of the valve seat has external hexagonal head structure. Two springs and spring covers are installed in the valve seat in sequence, and the first spring is a conical spring with large end upward to ensure stable opening. 2. The upper end of the valve rod of the hydraulic cartridge relief valve is fixedly connected to the spring cover and has screws. The middle of the spring cover has a downward protruding rod-shaped body, and the second spring is sleeved on the rod-shaped body. The lower end of the valve rod has an overflow valve spool, and the lower end of the second spring is installed in the spring seat. 3. The oil replenishing valve spool with overflow valve port is set under the spring seat. There is an oil port between the oil replenishing valve spool and the spring seat. The valve rod passes through the overflow valve port. The oil replenishing valve spool and spring seat are in an integral structure. The oil replenishing valve spool has a ball sealing surface, and the overflow valve spool has a conical sealing surface. AAK hydraulic cartridge relief valve is non-clogged and has 3 advantages.

Romeo is from Argentina. At the beginning of this year, their customer customized a set of personalized hydraulic lifting equipment. The test run of the equipment was smooth. After the trial, the customer reported that the energy consumption of the equipment was a little high. After the inspection, the engineer found that the throttling loss of the hydraulic cartridge counterbalance valve is large when the load is low and the flow is large, which is the source of high energy consumption. They requested the manufacturer to optimize the hydraulic cartridge counterbalance valve. The manufacturer tried for 4 weeks but no result. Romeo contacted some other hydraulic cartridge valve manufacturers, but there was still no good plan. The customer had been pushing for update, Romeo had no idea yet and was very worried. Romeo found me through the introduction of Patrick, an old customer of AAK. According to the situation described by Romeo, AAK technical team pondered the original hydraulic cartridge counterbalance valve drawing and system schematic diagram, 2 days later, the preliminary plan was formed. After 50 days, AAK sent 12 hydraulic cartridge counterbalance valve samples. Last week, Romeo emailed us to inform that after AAK hydraulic cartridge counterbalance valve was installed in the equipment, the throttling was improved under low load and large flow. The energy consumption was 20% lower than before, the customer was very satisfied. Their engineers were surprised that AAK technical team optimized the original hydraulic cartridge counterbalance valve from these 3 aspects, and added a new function, namely, variable pilot ratio. The hydraulic cartridge counterbalance valve with variable pilot ratio has a special structure. 1. The optimized hydraulic cartridge counterbalance valve body is provided with a control oil port. The two ends of the control piston include the first acting surface and the second acting surface. The valve cage is provided with a first chamber which is close to the first acting surface. 2. The control piston is provided with an annular boss which is close to the end face of one side of the first chamber. One end of the valve spool is against the second acting surface, and the end cover is connected with the control piston in a sliding seal. 3. The end cover is also provided with an annular boss to form an annular groove of the sliding seal and a connecting oil passage, and the annular groove is close to the end face of one side of the first chamber. The second chamber is formed between the two working surfaces of the piston, which can easily realize the function of controlling the piston. The optimized hydraulic cartridge counterbalance valve has the characteristics of variable pilot ratio and pilot pressure while the load moves stably. The performance of low pilot ratio and high pilot ratio can be realized according to different working conditions. The pilot pressure of the hydraulic cartridge counterbalance valve can be reduced by 20%, which is the highlight of 20% energy saving. AAK hydraulic cartridge counterbalance valve, with variable pilot ratio and pilot pressure, you can also have a small trial! https://www.aakindustry.com/info-det , ail/counterbalance-valves-aak445

During the 20th National Congress, leader of Hunan Province introduced the advantages of Hunan in the construction machinery industry: 1. In the time for a cup of tea, more than ten thousand parts of a locomotive were gathered in a 5 km radius. 2. One excavator can be off the line in 5 minutes. 3. Among the top 5 global construction machinery industries, Hunan accounts for 2.   From the above 3 points, we can see that there are 2 key technologies in the Chinese market: a complete industry and technology chain and the world's largest market. This is the speed of China and the advantage of China's machinery industry. I think any organization in the machinery industry can hardly be separated from China. This is also the reason why big brands, such as SUN Hydraulics and HydraForce have set up factories in China.   9 years ago, AAK Hydraulic Valve realized that the manufacturing of hydraulic cartridge valves alone was difficult to reflect the advantages of AAK compared with its peers, thus it extended from hydraulic cartridge valves to hydraulic units, which are hydraulic manifolds. Up to now, AAK has been the hydraulic manifold supplier of Honeywell for 6 consecutive years.   What are the advantages of purchasing hydraulic manifolds from AAK? In the words of Honeywell's purchasing director, it saves time, costs and links. 1. Shorten the whole procurement process: plugs, connectors and hydraulic valve blocks can be produced in AAK. Purchasing and tracking from multiple factories have become a one-stop process from AAK. 2. The installation process is simplified: AAK hydraulic units or manifolds can be directly installed into the equipment, and customers do not need to test the manifolds separately. 3. Undertake design services: from the hydraulic principle, oil circuit design, hydraulic valve selection, AAK 100% personalized customization. It is hard to engage in manufacturing industry, especially the hydraulic unit, the hydraulic manifold with technology, which is slower, more stupid and more solid than others. It is the smart people who make toil efforts. There is no shortcut to this road. There is no safe haven. Without “1”, the manufacturing quality takes the lead in the front, any more 0 after will eventually return to zero. Just like life, whether you can stand on the waves, and whether you can hold on the bottom of the waves.   From Hunan above to talk about Ningbo. Ningbo is the hometown of hydraulic valves in China, just hydraulic screw-in cartridge valves, there are more than 200 factories. An old American customer asked me a question: What is the current situation of Chinese hydraulic valve manufacturers? In fact, it is also the situation of Ningbo hydraulic valve manufacturers. My answer is as follows: There are 230 registered hydraulic valve manufacturers in Ningbo, 40 of them, whose manufacturing quality can be recognized, less than 10 are benchmarking SUN hydraulics and HydraForce, and less than 3 are capable of developing hydraulic manifolds independently.   AAK hydraulic manifolds lead the industry in 3 aspects: 1）Hard power of manufacturing quality 2）Skillful strength of part innovation 3）Soft power of network trust   In terms of personalized customization of hydraulic manifolds, it is not difficult to combine, vary and graft some hydraulic unit structures to create something new. It is better to use your limited life to do something that can leave a mark on this beautiful planet than to make some so-called patents that can not create any value. At that time, when old at the end of my life, I will think that I have lived for so many years, and made so many hydraulic manifolds to run on the earth, that is enough without regret. AAK hydraulic manifolds, 3 benefits, 3 strengths, you can also try a small order. https://www.aakindustry.com/info , -detail/hydraulic-manifolds-aak387

Sven from Sweden has been purchasing from hydraulic cartridge valve manufacturers in Europe for over a year. At the beginning of this year, his boss requested him to try purchasing from hydraulic cartridge valve manufacturers in China. Unexpectedly, the first time he purchased a hydraulic cartridge pressure control valve, problem occurred. The hydraulic cartridge pressure control valve purchased from the original hydraulic cartridge valve manufacturer has a lifespan of only 3-4 months, and the root cause is leakage at the connection between the valve cage and valve body. The original manufacturer blamed the cold climate for accelerating thread corrosion and causing leakage, which made Sven very helpless. Sven found hydraulic cartridge valve manufacturer AAK and left a message: 1. As soon as I searched for hydraulic cartridge valve manufacturers in China, I found AAK and looked forward to AAK's assistance. 2. Can the hydraulic cartridge valve manufacturer AAK provide hydraulic cartridge pressure control valves that operate in an environment of minus 40 degrees Celsius and have a service life of no less than 12 months? After communication, we learned that he had encountered a problem when purchasing hydraulic cartridge pressure control valves. Sven also provided me with the contact information of the original hydraulic cartridge valve manufacturer. The manufacturing capacity of this hydraulic cartridge valve manufacturer is still good. Why did he encounter such a problem? The installation and sealing details should not be in place, which accelerated the corrosion progress of the threads and reduced the service life by more than half. Sven learned that hydraulic cartridge valve manufacturer AAK supplied several Russian customers in low temperature environments, so he requested AAK to test the order. After 35 days, 20 hydraulic cartridge pressure control valves were sent out. Last Friday, Sven sent us an email stating that the hydraulic cartridge pressure control valve provided by AAK has been working for 6 months without any abnormalities. I told him that as long as the connection between the valve cage and valve body of the hydraulic cartridge pressure control valve is not stamped by external force, it will not loosen and there will be no leakage. How does AAK install the valve cage and valve body? There are details and skills here, as well as the awesome of the flow meter of the glue filling machine. 1. Details: The selection and configuration of AB adhesive. Most hydraulic cartridge valve manufacturers directly choose pre mixed sealants. AAK selects component A as epoxy resin curing agent and component B as hardening agent and filler. Then, according to the thread style, the ratio of A and B is determined and is now ready for use. AB adhesive has a high-strength bonding effect, strong sealing effect, corrosion resistance, and low temperature resistance, and is safe in environments ranging from -60 to 120 degrees Celsius. 2. Flow meter for glue dispenser: The amount of AB glue applied to the valve cage is also important, as more will affect installation, while less will affect sealing. Hydraulic cartridge valve manufacturer AAK uses elliptical gear flow meters, with different threads corresponding to different flow rates. I know that WINNER in Taiwan uses this flow meter, while other hydraulic cartridge valve manufacturers in China rarely use it. 3. Assembly technique: AB glue is evenly applied to the threads of the valve cage through the flow meter of the glue filling machine, then the valve cage is screwed into the valve body, and the valve body is tightened with a fixture. In humid and corrosive gas environments, without rigorous thread sealing, the threaded connections are prone to corrosion, leading to thread loosening. The 3 major advantages of installing hydraulic cartridge pressure control valves in AAK are low temperature resistance, easy resistance to corrosive substances, protecting the integrity of threaded connections, all of which extends the service life of hydraulic cartridge pressure control valves. AAK assembly has 3 major advantages, ensuring a service life of over 12 months for hydraulic cartridge pressure control valves at low temperatures. You can also give it a try.

However, there can be slight differences in their usage depending on regional preferences or context. Here's a general overview of the terms: Faucet: In American English, "faucet" is the more commonly used term. A faucet typically refers to a device that controls the flow of water in a plumbing system, specifically in the context of fixtures such as sinks, bathtubs, showers, or basins. Faucets are available in various styles, including single-handle, double- handle, and motion-sensing models. They can be operated by turning a handle, lever, or knob to regulate the water flow and temperature. Faucets may have additional features such as pull-out or pull-down sprayers for kitchen sinks, or integrated showerheads in the case of shower faucets. Tap: In British English and other English-speaking countries, "tap" is the more commonly used term. A tap typically refers to a device used to control the flow of water in plumbing systems, including both indoor and outdoor applications. Taps are commonly found in kitchens, bathrooms, gardens, and other areas where water outlets are needed. Taps can be operated by turning a handle or lever to open or close the valve, controlling the water flow. They may have separate taps for hot and cold water or a single tap with a mixer for regulating the water temperature. The term "tap" is also used to refer to a spigot or faucet-like device used to draw or dispense liquids from containers such as barrels or kegs. In summary, both "faucet" and "tap" generally refer to devices used to control the flow of water. The choice of term may depend on regional or cultural preferences, as well as the specific context of usage. What is the 1/2 Water Faucet Tap The phrase "1/2 Water Faucet Tap" typically refers to a type of water faucet or tap that is designed to connect to a water supply using a 1/2 inch (or sometimes written as 1/2") pipe thread. The "1/2" indicates the size of the pipe thread, which is a common standard for residential plumbing fittings. In plumbing terminology, the size of pipe threads is often measured in fractions of an inch, and the 1/2" size is a standard size for many household water faucets. This measurement refers to the diameter of the pipe thread that the faucet or tap connects to. So, when you come across the term "1/2 Water Faucet Tap," it typically means a faucet or tap that has a 1/2 inch pipe thread connection for water supply.
