Parker US50E17S1SN1JW Electric Unload Rel Valve

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.

Features:

• Cavity and mounting pattern according to ISO 7368 - for quick, easy integration
• Precise switching and hysteresis - for smooth and reliable operation
• High nominal flow rates up to 4000 l/min - optimum efficiency in relation to valve size
• 4 pressure stages - enables fine adjustment
• 6 sizes, NG16 to NG63 - makes selection easy
• Short delivery time - no warehousing necessary
• 2 switching types (series US*E)
• 3 adjustment modes:
  
  - hand knob
  
  - acorn nut with lead seal
  
  - cylinder lock
• Remote control via port X- Pilot operated unloading valve

Applications:

• Suitable for general hydraulic applications
