Cartridge Relief Valve

Ningbo Zhenhai Finotek Machinery Co.,Ltd is one of the leading China cartridge relief valve manufacturers and suppliers in China, welcome to buy or wholesale customized bulk cartridge relief valve from our factory.

Cartridge relief valve is used for limiting pressure in hydraulic circuit, so that to protect hydraulic components from pressure beyond normal pressure. Finotek cartridge relief valve is sensitive to pressure response and quick opening or close smoothly as per different pressure requirements. Cartridge relief valve should open quickly flows to oil tank through port2 as soon as the pressure at the inlet port 1 approach the pre-setting pressure of valve, with the function of throttle flow which limits the pressure abnormal rise.

Finotek cartridge relief valve is designed with low pressure rise versus flow smoothly and quickly, available used for in cross port relief circuits instead of in loading holding applications due to inner leakage
