| Message: | Joakim, from Greece, got stuck when he purchased the hydraulic cartridge relief valve for the first time from China. One of their hydraulic motors needs a hydraulic cartridge relief valve. Joakim purchased it from a cartridge valve manufacturer in Ningbo. However, during the test run, the motor was damaged due to the abnormal pressure buffering function of the hydraulic cartridge relief valve, which was also blamed by the engineer. The original manufacturer was not confident to improve the pressure buffering function of the hydraulic cartridge relief valve. Joakim contacted me. |
