Pilot operated Cartridge cartridge pressure relief valve designed to a combination of pilot operated pressure relief function and check function in a one valve. The pilot operated relief cartridge valve is mostly used for the occasion of changing loading direction, such as mounted in the line of connection with cylinder. When the cylinder piston is pressed, the pilot operated cartridge pressure relief valve will help to prevent overload in the chamber of cylinder. If the cylinder is pushed forwarder, the reverse fluid will flow through with minimum pressure different by pilot operated relief cartridge valve, avoiding vacuum phenomenon in the cylinder, it is also called overflow, prefill valve.

Finotek pilot operated cartridge pressure relief valve is equipped in hydraulic unit as pressure relief valve and one-way check valve, it is low noise, sensitive pressure response and large flow rate, better to replace modular valve in a compact designed valve block.
