Description

C 2.9533 Pressure reducing valves

Pressure reducing valves keep the outlet pressure constant, also in case of a changeable, but always higher inlet pressure. This version without overpressure function cannot compensate a pressure increase of the outlet pressure that exceeds the set pressure.

Below the set outlet pressure, the hydraulic oil flows unhindered from P to A. In case of a pressure increase the set spring force is overcome and a check valve cuts off the flow hermetically sealed. Thus, a further pressure increase is avoided, also in case of increasing inlet pressure p. In case of a pressure drop, e.g. because of a leakage at a cylinder, the check valve will be opened by a strong spring against the existing inlet pressure p. Hydraulic oil can continue flowing until the set outlet pressure is obtained. Increasing outlet pressure, e.g. due to temperature rise cannot be compensated by this pressure reducing valve. A return flow from A to P is only possible if the inlet pressure p drops below the set outlet pressure.

Versions

The pressure reducing valve C2.9533 is available as screw-in valve, for pipe thread or manifold-mounting connection.
