Short cycle times call for a fast pilot stage with a stable pilot pressure. The 4WRZ10W8-50-7X/6EG24N9TK4/D3M takes its pilot oil externally, returns it internally and controls 50 l/min at 315 bar. Spool symbol W8, 8.24 kg, up to 170 l/min of flow.

The step response of a pilot-operated valve hangs on the pilot pressure. The 4WRZ10W8-50-7X/6EG24N9TK4/D3M draws it from an external source and works at 50 l/min nominal flow in size 10.
Benefits
- External pilot oil supply with internal return, stable pilot pressure with one line fewer.
- 50 l/min nominal flow, 170 l/min maximum at 315 bar operating pressure.
- Spool symbol W8, 3 switching positions, 4 ports to ISO 4401-05-05-0-05.
- Pressure reducing valve in the pilot stage for a defined pilot pressure.
- 8.24 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.
