AAK Hydraulic Cartridge Relief Valve 3 advantages, Eugene had to give up the original manufacturer

After CNY, most of the hydraulic cartridge valve manufacturers in Ningbo started work on January 30. Because of the epidemic, many of us haven't returned to our hometown for 3 years, so AAK hydraulic cartridge valve started 3 days late, and also delayed answering the messages of some new customers in the CNY period. I reply to target new customers or new customers with clear messages first. 

Eugene, from Greece, left a message asking: How to solve the problems of unstable pressure regulation and squealing of hydraulic cartridge relief valve? After communication, it was learned that one of their hydraulic power units failed in the test run. The engineer found that the hydraulic cartridge relief valve was unstable in pressure regulation and there was a howl. This hydraulic cartridge relief valve was customized from a cartridge valve manufacturer in Ningbo, China.
