The task of pressure-reducing valves is to maintain a largely constant outlet pressure despite a higher and changing inlet pressure.

These valves are used when a secondary circuit has to be fed with a lower but constant pressure level by a main (primary) oil circuit with a higher and varying pressure level. The valves mentioned here are suitable for the supply of control circuits with low oil consumption. There is a designrelated permanent leakage flow, which has to be led back to the tank in a de-pressurized line via port R. A reversal of the flow direction is possible up to approx. 30% of Qmax. A bypass check valve has to be provided for higher reversed flow. These pressurereducing valves feature an override compensation, i.e. acting like a pressure-limiting valve, if the pressure on the secondary side exceeds the set pressure e.g. due to external forces.
Features and benefits:
■ Compact design
■ Numerous configurations
Intended applications:
■ For control oil supply in pilot circuits
