Miniature pressure reducing valves type ADC, AM etc. The task of pressure reducing valves in a hydraulic circuit is to maintain a rather constant outlet pressure despite a higher and changing inlet pressure. These valves are usually used when a secondary circuit has to be fed with a lower but constant pressure level by a main (primary) circuit with a higher and varying pressure level. These valves are intended for the supply of control circuits with low flow requirements. There is a design related permanent leakage flow, which has to be led back to the tank via a de-pressurized line. A reversal of the direction of flow is possible up to approx. 30% of Qmax. A by-pass check valve has to be provided for higher reversed flow. These pressure reducing valves feature a 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.
