If the plant already holds the pilot pressure at setpoint, no pressure reducing valve is needed inside the valve. The 4WRZ10W9-85-7X/6EG24N9K4/M does without one, controls 85 l/min nominal flow at 315 bar and draws pilot oil externally. It weighs 7.8 kg.

Total price
Many plants already hold the pilot pressure at setpoint centrally. The 4WRZ10W9-85-7X/6EG24N9K4/M therefore leaves out a pressure reducing valve of its own in the pilot stage and controls 85 l/min nominal flow in size 10.
Benefits
- Without a pressure reducing valve in the pilot stage, for plants with an already regulated pilot pressure.
- 85 l/min nominal flow, 170 l/min maximum flow at 315 bar operating pressure.
- External pilot oil supply and external return, a dedicated pilot circuit.
- Spool symbol W9, 3 switching positions across 4 ports to ISO 4401-05-05-0-05.
- 7.8 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.

Applications
The valve is intended for plants with a central pilot pressure supply feeding several valves from the same source. Leaving out a reducing valve removes a part that would have to be set and checked. Concealed auxiliary actuation remains available for emergency moves.
