MODULAR RELIEF VALVE

MRF-02 SERIES

The modular adjustable relief valve is designed to limit the operating pressure in a hydraulic system or in a branch of the system to a maximum set pressure. The internal piston moves to smoothly relieve the pressure when the system pressure reaches the desired setting, maintaining stable pressure control and repeatability.

Pressure relief is available on the P, A, B, and A & B ports. Adjustment is made with a calibrated knob, standard with the valve.

As a modular valve, this valve mounts between an NFPA D03 size directional control valve and the subplate. A longer than standard bolt kit is required when mounting modular valves in a stack. Refer to bolt kits.
