AAK Hydraulic Threaded Cartridge Valve Service Life Twice Long of its Peers

Barnaby is from Brazil, has purchased hydraulic threaded cartridge valves in Ningbo for 5 years. He has purchased several standard parts of SUN cartridge valves from AAK. He always thinks that AAK cartridge valves are expensive. At the beginning of last year, the customer complained that their hydraulic cartridge valve, installed in the hydraulic power unit, had leaked in 6 months. The original hydraulic cartridge valve manufacturer said that the seal ring structure was damaged in the assembly process, and the seal ring could only be replaced, but after 1 month, there was leakage again. Barnaby realized that the hydraulic threaded cartridge valve from this manufacturer has a service life of only 6 months. The boss is not satisfied with his purchase. There are always complaints from customers. Barnaby feels the pressure from the boss.
