Cartridge pressure relief valve is designed with a pressure relief function and check function together in one cartridge valve. When the operation pressure at the T port reaches the valve pre-setting pressure, the cartridge valve starts to open and let the flow out through T port to oil tank.

Finotek cartridge pressure relief valve is often installed in the hydraulic system before the cylinder to protect the cylinder while working, to avoid vacuum phenomenon happened in chamber of cylinder. Note: The cracking pressure of check valve should be smaller than different pressure offered by hydraulic system, otherwise, the valve will no use for avoiding vacuum phenomenon in hydraulic units.
