Back pressure valves are an essential component for enhancing the performance of chemical dosing systems.The back pressure valves we manufactured are suitable for use with a wide range of corrosive liquids and air. They come with diaphragms made of PFTE or EPDM and are available in various materials, such as PVC, PVDF, carbon steel, SS304, and SS316L. Our back pressure valves have an adjustable pressure range from 10Kpa to 31.5Mpa and are available with either thread or flange connections, which can be customized according to your needs.contact us for more details.

Erik compared more than 20 hydraulic pilot pressure control valve factories. No manufacturer can do the hydraulic pilot operated pressure control valves which can be used under high pressure above 450bar for more than one year. AAK hydraulic pilot operated pressure control valve passes the test at one time, and there is no abnormality after one year of use. Erik is from a German hydraulic equipment manufacturer. In the first half of last year, the company needed to purchase a special hydraulic pilot operated pressure control valve with a working pressure of more than 450 bar, a service life of more than one year and a durability of more than 2 million times. The boss realized that it was some difficult to purchase the hydraulic pilot operated pressure control valve this time, and asked Erik and his colleague to purchase at the same time. Whoever successfully purchased the hydraulic pilot operated pressure control valve first will be promoted and raised. Erik is full of energy and keeps looking for hydraulic pilot operated pressure control valve factories online and offline. He contacted more than 20 new suppliers, including AAK hydraulic valve. Most of the hydraulic pilot operated pressure control valve manufacturers replied that they need to be customized from the beginning of materials, and it takes 25 days to sample this special hydraulic pilot operated pressure control valve. Erik chose two factories to test the samples. A month later, Erik received the samples and asked the engineer to test them. The results failed, but the hydraulic pilot operated pressure control valve obtained by his colleague passed the first test, which made Erik very depressed. Fortunately, this is just in the test stage, the final effect depends on the test results of the hydraulic pilot operated pressure control valve one year later. Erik contacted AAK for the second time. He clearly informed that the samples of hydraulic pilot operated pressure control valves he selected in the first round failed. For the first time, he did not choose AAK because AAK needed 35 days. This time, he only asked AAK to make samples. Whether he can win or not, he can only count on AAK. Because the material selection and internal test of hydraulic pilot operated pressure control valves need time, Erik also understands the difficulties of making the samples. After 35 days, AAK sent 6 samples of hydraulic pilot operated pressure control valves. Last week, almost a year after the hydraulic pilot operated pressure control valve samples were sent, Erik sent an email to inform that AAK hydraulic pilot operated pressure control valve was the only sample that passed 2 million tests, and there was no abnormality after one year of use. Although his colleague's sample passed the early test, it could not withstand the high pressure above 450 bar for enough time, it leaked in less than a year.

AAK pilot hydraulic pressure valve adds welded high-strength filter screen at the inlet section of slender hole, and the damping hole is 100% unblocked. Colin faced 4 times of hydraulic pressure valve approval failures, which were solved at one time by AAK hydraulic valve. Many hydraulic valve manufacturers believe that the pilot hydraulic pressure valve has fine impurities and is easy to block the pilot stage slender hole, which is determined by the special structure of the hydraulic valve. Therefore, they just remind customers to use high-purity hydraulic oil and never reflect on their production process, resulting in many hydraulic valve customers falling over here. Colin is the purchasing supervisor of a hydraulic valve company in Germany. He has a batch of orders for pilot hydraulic pressure valves recently. During sample approval stage, it was found that some fine impurities could easily block the pilot stage slender hole, resulting in the blockage of the damping hole, the loss of pressure of the pilot stage and the failure of the pressure valve. The hydraulic pressure valve sample was modified for 4 times, but it was still unapproved. Colin looked for no less than 20 hydraulic valve manufacturers within 7 days, and only got a reply from 3 hydraulic valve manufacturers: they could not make sure that the damping hole was 100% unblocked. The remaining more than 20 hydraulic valve manufacturers did not give any reply at all. Colin happened to see an article about damping hole blockage of AAK hydraulic valve on B2B website. With a try attitude, he contacted us AAK hydraulic valve and asked about the treatment of damping hole blockage. After we asked him about the parameter requirements and use scenarios of his hydraulic pressure valve, we said there was no problem and could rest assured to proofing. Colin didn't think too much either. He tried again with the mentality of making every possible effort. Unexpectedly, the pilot hydraulic pressure valve sample made by AAK not only passed the testing but also solved the problem of damping hole blockage, and the pressure debugging was more sensitive and stable. The next day, he transferred the hydraulic pressure valve order to AAK. He wondered why hydraulic pressure valve of AAK proofing passed testing at one time. In order to deal with severe working conditions more effectively, AAK hydraulic valve reduces the impact of oil pollution on the pressure valve, and has optimized and upgraded the pilot hydraulic pressure valve process for a long time. While improving the oil inlet stability, the welded integral high-strength filter screen and local turbulent self-cleaning function are added to the inlet section of the pilot slender hole, so as to reduce the impact of oil pollution on the normal operation of the hydraulic valve. The opening and overflow characteristics of the hydraulic pressure valve are better, and the pressure curve is less affected by the change of overflow flow
