Pilot operated cartridge relief valve with C-10-2 cavity is standard SAE threaded of 7/8”-14, the max. flow rate of C-10-2 cavity, pilot operated cartridge relief valve reaches to 113L/Min. and small leakage with lower than 3ml/min. The standard cavity of C-10-2 valve is usually fitting in various brand of manifolds as pressure relief valve. The relief pressure is available to be preset or adjustment as per different working requirement.

Finoteks’ pilot operated cartridge relief valve with C10-2 cavity is produced for pressure control connected with P and T port. The pilot operated cartridge relief valve part of adjustment is allowed to be screwed with hand wheel or straight-slow screw. Main part like valve poppet, valve seat is precision manufacturing processing and hardened treatment for longer service life.
