Fewer parts in the pilot stage mean less setting work. The 4WRZ10W9-25-7X/6EG24N9K4/M works without a pressure reducing valve, controls 25 l/min nominal flow at 315 bar and weighs 7.74 kg in size 10. Pilot oil is supplied and returned externally.

Total price
Every adjustment point in the pilot stage is a source of error during commissioning. The 4WRZ10W9-25-7X/6EG24N9K4/M leaves the pressure reducing valve out and controls at 25 l/min nominal flow.
Benefits
- 25 l/min nominal flow for fine resolution, up to 170 l/min flow.
- Without a pressure reducing valve in the pilot stage, one adjustment point fewer at commissioning.
- External pilot oil supply and external return at 315 bar operating pressure.
- Spool symbol W9 with 3 switching positions across 4 ports.
- 7.74 kg, 24 VDC, NBR seals, subplate mounting to ISO 4401-05-05-0-05.
