MODULAR RELIEF VALVEMRF-02 SERIES

FEATURESThe modular adjustable relief valve is designed to limit the opera ng pressure in a hydraulic system orin a branch of the system to a maximum set pressure. The internal piston moves to smoothly relieve thepressure when the system pressure reaches the desired se ng, maintaining stable pressure control andrepeatability.

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 direc onal control valve and the sub -plate. A longer than standard bolt kit is required when moun ng modular valves in a stack. Refer to boltkits.

MODULAR RELIEF VALVEMPR-02 SERIES

FEATURES

The modular adjustable pressure reducing valve will ensure that the opera ng pressure in a branch of a hydraulic system will be maintained at a lower se ng than that of the main system pressure. The valvefunc ons on the selected P, A, or B port and is internally drained. Adjustment is made with a calibratedknob, standard with the valve.
