Unloading Valve – Series UR*E / US*E

The unloading valves series UR*E and US*E are used to unload a circuit at low pressure and provide a very precise switching and hysteresis for smooth operation. A wide range of sizes and pressure stages makes them almost universally applicable.

Both valves consist of a mechanical pilot stage and a slip-in cartridge main stage. The mechanically adjustable pressure signal to unload the main stage has to be applied to port X. The nominal pressure differential between opening and closing is 15 %. Series US*E is additionally vented by electrical operation. The UR*E/US*E model codes embrace the pilot valves, covers and cartridges that are also offered as separate items.
