Design:
Cylinder body made of steel, phosphatized. Remaining parts made of tempering steel. Valve seat and piston are hardened and ground. This valve is leak free.
Application:
The stop valve shuts the flow from P to A when the pressure set A is reached. It opens when the pressure at A falls below the set value (e.g. through leakage).
1. Single-circuit system: The pressure reducing valve is used in a hydraulic circuit, where part of the cylinders are only to receive a reduced pressure (e.g. to prevent distortion of the workpieces or for positioning).
2. Dual-circuit system: If two working circuits are to be operated with different pressures from a single pump unit, the pressure of one circuit must be reduced by inserting a pressure reducing valve.
