Different from 90% of the hydraulic valve manufacturers, AAK hydraulic valve sleeve is made of 40Cr material, which will not cause stuck phenomenon. It saves David's hydraulic valve market in Italy in time, and our company has gradually become his main supplier.

The selection of valve sleeve material is directly related to the performance of hydraulic valve. The domestic 1214 steel is easy to cut and has high output. At the same time, the loss of machining blade is relatively small. At present, in order to save cost, the vast majority of peers use domestic 1214 steel as valve sleeve, which often ignores the potential problems, such as brittleness and easy deformation during heat treatment. If the valve sleeve is deformed, it will cause the spring base to jam and malfunction in the process of tightening and loosening, and affect the pressure and flow control. Currently, the valves produced by vast majority of manufacturers have these hidden dangers.

David from Italy is mainly responsible for the purchasing of hydraulic valves in East China in the past two years. Last year, he purchased a batch of pilot hydraulic valves from our hydraulic peers. There was no problem in the production and assembly, even after the test on the pressure test bench. The market sales data of this order was also very optimistic. David's team was planning to re-peat the order and double the qty. However, at the same time, he received complaints from 30% of customers. The problem is all the same that the spring base is stuck and after being adjusted for two or three times, it becomes loose, and the control of pressure and flow almost fails.
