Cartridge pressure relief valves installed in nearly all of the hydraulic systems, usually called pressure relief valve or relief. The main inner component of relief cartridge valve are valve body, spool/poppet and spring, the oil inlet port of the cartridge pressure relief valve is named P port and T port for pressure outlet. The key purpose of cartridge pressure relief valve is to limit the working pressure in hydraulic systems or units, therefore, the cartridge relief valve controls pressure, instead of generating pressure.

Finotek cartridge pressure relief valve is available used for limiting max. hydraulic pressure, preventing sudden pressure shock of higher pressure, avoiding damage main operation devices such as motors, cylinder, pumps etc.
