Fine return filters build back pressure that detunes the pilot stage. This version therefore drains pilot oil separately, meters 50 l/min nominal flow at up to 315 bar and follows a ±10 V setpoint. Mass 8.46 kg.

Total price
A fine return filter costs pressure, and that back pressure shifts the pilot null position. The 4WRZE10W8-50-7X/6EG24N9EK31/A1D3V avoids it through an external pilot drain on internal supply, at 50 l/min and 315 bar.
Benefits
- External pilot drain - filter back pressure in the main return no longer affects control.
- Internal pilot oil supply, so only one extra line to route.
- 50 l/min nominal flow, 170 l/min maximum throughput, 315 bar operating pressure.
- ±10 V setpoint, on-board electronics, 24 VDC supply.
- Mass 8.46 kg, spool symbol W8, FKM seals, ISO 4401-05-05-0-05 interface.
