Find Verified Hydraulic Cartridge Relief Valve 3 Advantages Suppliers, Manufacturers and Wholesalers

3 Advantages of AAK hydraulic cartridge relief valve, , a hydraulic customer from Bolivia, failed to purchase hydraulic cartridge relief valves from for the first time. has purchased hydraulic components from local hydraulic cartridge valve manufacturers in Bolivia for 3 years. He heard from his peers that the cost performance of purchasing from is better than that of Bolivian hydraulic valve manufacturers, so he began his overseas procurement trip. A hydraulic cartridge relief valve with rated pressure exceeding 30MPa, and the fit clearance between valve body and valve spool is required to be 0.006~0.01mm. successively tried samples with 3 hydraulic cartridge relief valve manufacturers in 70 days. The hydraulic cartridge relief valve samples had either internal and external leakage, blocked oil circuit, or even stuck. 3 times of proofing failed, which made helpless and even suspected that he was misled by his domestic peers. Richard noticed AAK on the B2B website and saw some tweets and customer cases to solve the problems of hydraulic cartridge valves, especially some big brands such as HydraForce and SUN Hydraulics, are also loyal customers of AAK for many years. He seemed to see hope and left a message to us: How much MPa can the rated pressure of the hydraulic cartridge relief valve with a clearance of 0.006~0.01mm between the valve body and the valve spool be? When I saw this message, I subconsciously felt that he had stumbled in the accuracy when purchasing this hydraulic cartridge relief valve, and he was inexperienced in choosing the hydraulic cartridge valve manufacturer. According to the problems of his hydraulic cartridge relief valve samples, AAK technical team determined that the problem was caused by burrs inside the hydraulic cartridge relief valve. However, the specific problem still depends on the sample analysis. I suggested Richard making samples directly to see the manufacturing quality of AAK hydraulic relief valves. Maybe that will change his view on China hydraulic cartridge valve manufacturers. After 30 days, AAK sent 10 samples of hydraulic cartridge relief valve. 6 months later, Richard emailed us that AAK hydraulic cartridge relief valves did not have the problems of "internal and external leakage, or blockage of the oil path or stagnation" that occurred in other hydraulic cartridge valve manufacturers, which also strengthened his confidence in purchasing from China hydraulic cartridge valve manufacturers. How to effectively avoid burrs of hydraulic cartridge relief valves? It is also a "thorn" that AAK has to remove since it was engaged in the R&D and manufacturing of hydraulic components. With 13 years of manufacturing experience, AAK can be sensitive to find problems and solve them. In the processing of hydraulic cartridge relief valves,

For hydraulic relief valve with 3 high requirements, Ellenburger spent 6 months without results, and AAK succeeded in sample at 1 time I always remember an unusual inquiry email about hydraulic relief valve from Ellenburger, a Russian customer, at the beginning of this year. The email subject was "Don't reply if without ability and confidence", he should have been in trouble at other manufacturers. The content of the email was about testing 20 hydraulic relief valves, with detailed part processing drawings and parameter requirements attached. That was a hydraulic relief valve with high requirements, and the accuracy of valve hole is required to be within 2�¼M, the material hardness of the valve spool is HRC68, and the surface of the valve body is galvanized nickel alloy, which must withstand high pressure of 450bar. In addition, the durability test of the hydraulic relief valve must pass 2 million times. The requirements in terms of manufacturing quality, function and performance for this hydraulic relief valve is all clearly indicated. After more than 3 hours of discussion by AAK engineers, I replied to Ellenburger that AAK was able to produce this hydraulic relief valve at a development cost of 2,500 US dollars. After the email was sent, there was no reply, and I didn't follow up. Because I believe there are few manufacturers who can make this hydraulic relief valve. For example, in Ningbo, the "hometown of hydraulic valves in China", perhaps only 3 factories have this technical ability. 3 months later, Ellenburger suddenly asked our bank account number. He wanted to pay us to sample the hydraulic relief valve. I was also a little confused. After several rounds of communication, it was learned that the hydraulic relief valve had been developed for half a year, he found more than 20 manufacturers, communicated with more than 300 emails in total, and paid the development cost for 3 times, but all failed, and his mood was extremely bad. Ellenburger said that when he saw AAK reply that we can produce this hydraulic relief valve, his first feeling was that the manufacturer who responded so quickly should not be very good, so he ignored us. He thought that AAK would certainly follow up by email within a week, but to his surprise, AAK didn't send any email for a month, so he began to pay attention to AAK hydraulic valve slowly. In AAK website, he saw the stories between AAK and many customers, and some cases made him admire AAK very much, therefore, he believes that AAK is the ideal manufacturer of his samples this time. I was also moved by him and promised him that if AAK sample failed, I would be willing to return the development fee. At the same time, I also reminded him that if AAK could not get the hydraulic relief valve done successfully, there was no need to find other hydraulic relief valve manufacturers in Ningbo. After 45 days, 20 samples of hydraulic relief valves were sent after passing the internal test.

AAK Hydraulic Flow Control Valve with 3 major advantages, recognized by Yagmur Yagmur is from T�¼rkiye and mainly purchases hydraulic cartridge valve standard parts from Ningbo. Recently, they developed a hydraulic drilling equipment that uses hydraulic flow control valves that are modeled after HydraForce standard parts, and purchased from a hydraulic valve manufacturer in Ningbo. During equipment debugging, it was found that the flow rate of the hydraulic flow control valve was unstable, and the leakage rate did not match the hydraulic system. The original hydraulic flow control valve manufacturer stated that this is a replica of HydraForce and is unwilling to optimize its function for several hydraulic flow control valve samples. Yagmur checked with several other hydraulic valve manufacturers, but they were not interested. Yamour was very anxious. The original hydraulic flow control valve manufacturer introduced AAK to Yagmur. After communication, it was learned that her requirements for this model include low leakage and high precision requirements for valve holes. Based on the hydraulic system schematic provided by her and the industry model code of the HydraForce hydraulic flow control valve, I recommended a ready-made sample to her. As long as the external dimensions meet his manifold requirements, it can solve the problem she is currently facing. 2 weeks after the sample was sent out, Yagmur informed via email that the drilling equipment was successfully debugged. The low leakage of AAK hydraulic flow control valve meets their system requirements, especially the flow control function that they are very satisfied with. I told her that for this AAK hydraulic flow control valve, we have 3 major advantages: 1. The internal leakage of AAK hydraulic flow control valve is 5 drops/min, while most peers can only achieve 8-10 drops/min. 2. The hole accuracy of AAK hydraulic flow control valve can reach IT6-IT7 level, and the surface roughness can reach Ra0.2-0.025m. 3. The AAK hydraulic flow control valve function fully aligns with the standard parts of HydraForce, and there are probably no more than 3 manufacturers in Ningbo to meet it. The vast majority of hydraulic flow control valve manufacturers in the industry do not use forming cutters for machining small quantities of hydraulic flow control valves, but use CNC instead to process according to dimensional requirements. The result of this machining is an accuracy of 0.03mm and a positional tolerance of 0.02mm. The AAK hydraulic flow control valve is processed with forming tools, and the dimensional accuracy of the valve hole after processing reaches 0.01mm, with a positional tolerance within 0.007mm. At the same time, AAK has its own standards for tool selection, with hardness of HRA90 alloy material, heat resistance of 900 , valve hole accuracy of IT6-IT7 level, surface roughness of Ra0.2-0.02m, and tool life is 30 times higher than ordinary alloy steel.

AAK Optimized the Hydraulic Direct Acting Cartridge Relief Valve with 3 tricks, Gaylord gave up the original Indian manufacturer Gaylord comes from Holland and is an old customer of AAK hydraulic valve. Some time ago, he emailed me to ask if AAK could optimize a hydraulic direct acting cartridge relief valve. After communication, I learned that at the beginning of the year, they had an order for a hydraulic power unit for high-precision machine tools, which used a hydraulic direct acting cartridge relief valve. Gaylord chose an Indian hydraulic cartridge valve manufacturer to make samples, and the equipment debugging was not smooth. The hydraulic direct acting cartridge relief valve had unstable overflow liquid, forming a jet, especially under low pressure, the stability of the system was poor. Although the function test of the valve was normal, it was still necessary to optimize the hydraulic direct acting cartridge relief valve, but 2 weeks later, the original manufacturer still had no solution, and Gaylord contacted me. According to his hydraulic system schematic diagram and the drawing of the original hydraulic direct acting cartridge relief valve, AAK engineers found the hidden danger of the original structure. Gaylord sent the PO of the test order. After 50 days, AAK sent 10 samples of hydraulic direct acting cartridge relief valves. A month later, Gaylord sent us an email. The equipment was adjusted smoothly. Under low pressure, the system was stable. The customer was also satisfied with the prototype. His engineers also admired the brains of AAK technical team. AAK hydraulic direct acting cartridge relief valve has good stability under low pressure conditions. The key lies in its unique structure: 1. The valve spool, spring, plunger and pressure regulating knob are successively installed in the cavity of the hydraulic cartridge relief valve body. The valve spool contacts the valve seat under the elastic force of the spring, and relies on the elastic force of the spring and the back pressure of the overflow port to balance the hydraulic pressure generated by the oil inlet. 2. The original poppet valve spool is changed into an integral ball type valve spool, and an annular gasket is set between the ball valve spool and the spring. The ball valve spool can automatically adjust the axial angle relative to the centering bearing, which improves the stability of the valve and ensures the low pressure stability of the hydraulic system. 3. Before assembly, the standard steel ball is used to punch the runner port and gasket port that contact the steel ball. The original wire seal is changed to ring seal to improve the sealing performance, so as to ensure the reliable contact between the gasket and the steel ball and realize the stable overflow function. AAK hydraulic direct acting cartridge relief valve, is also stable in low pressure, you can also try a small order!

hydraulic relief valves . purchased a batch of hydraulic relief valves for crane system in because the original supplier was not able to meet the delivery. He sent an email last week saying with hydraulic relief valves, the stability is 8% higher than that of the original supplier, and there is almost no external leakage. This surprised him. The use experience of hydraulic relief valves has benchmarked with their previous local hydraulic relief valve manufacturers The vast majority of hydraulic valve bodies are made of nodular iron, vermicular iron and gray iron and cast with resin sand as the molding medium. Therefore, there is sticky sand in the casting, which is easy to pollute the oil system and block the valve and filter, which is the key factor affecting the stability of hydraulic relief valves. Most of the common sand cleaning methods of hydraulic relief valves used in the industry are shot blasting and electrochemical sand cleaning, all of which have limitations. 1. Shot blasting can not completely remove the sticking sand from the valve hole with complex structure and small oil passage, which is easy to affect the tightness and product accuracy, and is not conducive to the stability of the hydraulic relief valves. 2. Electrochemical sand cleaning can relatively remove the sticky sand in the narrow oil passage, but it has high energy consumption, high operation intensity of workers, easy to have human errors, can not completely remove the sticky sand, and is not conducive to the stability of the hydraulic relief valves. Improving the quality of hydraulic parts processing process, improving the cleanliness level and ensuring the stability of hydraulic relief valves has always been the hard index of hydraulic relief valves. Auxiliary processing of hydraulic parts mainly includes: sand cleaning of valve body, deburring or residue treatment of parts and cleaning of hydraulic parts. How does do the sand cleaning of hydraulic relief valves technical team has continuously improved the sand cleaning process of hydraulic relief valves after years of technical improvement. For the sand cleaning of small complex castings, has its own unique sand cleaning 5 methods, namely: artificial aging - Pickling - rinsing - rust prevention - ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting to peel the sand from the casting, and then the explosion of compressed air during ultrasonic cleaning is used to peel off the sand, so as to achieve the purpose of sand cleaning. has its own unique advantages of sand cleaning 5 methods: (1) it is less affected by the casting structure; (2) it is

new hydraulic relief valve. The drawings of the hydraulic relief valve were sent 1 month after the confidentiality agreement was signed. The customer requested that if we were not able to develop it, they would witness us destroy the drawings and documents of the hydraulic relief valve by video. It's the first time for this customer to be so formal After receiving the drawings of hydraulic relief valve, we knew that it was to match with a set of aerospace equipment developed by a world top 500 enterprise in the engineers reviewed the drawings for 3 days and still didn't write the sample program. This hydraulic relief valve is not only small in size, but also has material requirements, machining accuracy requirements and use frequency requirements that exceed the parameter requirements of the hydraulic relief valves we have seen. We estimated that the overall development When we mentioned and give you 1 year of time. If the development is successful, you can wait for the order of hydraulic relief valve. If the development fails, this will be deducted from the payment for in the future. to say that the customer will prepay for the development cost of the hydraulic relief valve, but if it fails, we will need to refund it by deducting from the future payment gradually. I did not hesitate to reply to the email and was willing to try to develop this hydraulic relief valve. hydraulic relief valve development would be counted as the contribution of the technical team, and the failure would be counted as mine, because I can't fail to live up to the customer's support for our development. Some people in can not understand how this could be a kind of support. Maybe he didn't think about a question, that is, what would the mentality of the technical team be without customer support Behind these are two completely different ways of thinking. One is that if you haven't done it yet, think about failure first, think about whether there is a bottom plan first, and if not, don't do it. There is also a way of thinking, which is to think about how to start first. If conditions permit, start working first. The difference between these two ways of thinking is not just the difference between conservative and radical, but whether people are the key factor to create value. With the starting money, the hard work of the technical team and the best logistics

When I opened the mailbox this morning, I saw an from , which should be a re-order for the hydraulic relief valve, because he asked about the durability of hydraulic relief valve spool last week. Opening the , it is indeed the need for purchasing a large number of 420 hydraulic relief valves, and requiring 3 years of quality guarantee. is a purchaser of . 3 years ago, a customer of his company complained that the crane was easy to depressurize during work, resulting in the inability of the crane to bear the force. Especially after the working temperature reaches 55 C, the pressure cannot go up. Field engineers believe that this is a problem of the hydraulic system, such as low pressure regulation of the hydraulic relief valve, wear of the hydraulic system, or oil pollution. No abnormality was found after inspection. Finally, it was determined that the fault occurred on the hydraulic relief valve. After disassembling the hydraulic relief valve, it was found that the cone valve spool was worn, affecting the sealing of the hydraulic system, so the oil pressure could not rise. The customer does not understand why the valve spool of this hydraulic relief valve is worn after less than 2 years of use. The customer requested to replace with a batch of hydraulic relief valves with durability of more than 3 years and use them on these 12 faulty cranes. At that time, contacted more than 10 hydraulic relief valve manufacturers and got reply that the warranty could not be achieved for 3 years. Some hydraulic valve manufacturers replied that they only have 50% confidence. This result embarrassed Bruce. The customer requirements for the hydraulic relief valve could not be implemented, how he should explain to the owner. I received message from on the of can really provide a 3-year warranty hydraulic relief valve I replied directly: just give it a try then you will know. I can't make money with the trial orders of several samples, and you can't lose money. Maybe was stimulated and sent us the test order the next day for 4 hydraulic relief valves. also frankly told that two other hydraulic valve manufacturers would also try the order at the same time. Their plan is that each factory will be tested for 4 samples, with a total of 12 hydraulic relief valves to meet the urgent needs of customer first. About 2 years after the samples were sent, we received from again for another trial order of 8 hydraulic relief valves. I felt strange and thought that they actually didn't have big quantity order for hydraulic valves. Until last week, from his email, we learnt that they had tested the hydraulic relief valves provided by for 3 years. Indeed, 3 years later, hydraulic relief valves still worked normally, and the hydraulic relief valves provided by the other two manufacturers had faults in less than 2 years.
