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.

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.

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.

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, which plays a very good protective role for the system.
