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
