A separately drained pilot return keeps control free of back pressure in the tank line. This valve uses exactly that arrangement, meters 85 l/min nominal flow up to 315 bar and follows a ±10 V setpoint. Spool symbol W8, mass 8.47 kg.

Total price
High back pressure in the tank line distorts pilot behaviour. The 4WRZE10W8-85-7X/6EG24N9EK31/A1D3V therefore takes pilot oil internally but drains it externally, while metering 85 l/min at up to 315 bar.
Benefits
- Internal pilot supply with external return - control behaviour independent of tank back pressure.
- 85 l/min nominal flow in size 10, 170 l/min maximum throughput.
- ±10 V setpoint, on-board electronics, 24 VDC supply.
- Operating pressure up to 315 bar, spool symbol W8, 3 switching positions.
- Mass 8.47 kg, FKM seals, HL hydraulic fluid.

Applications
Recommended for plants running long or heavily filtered return paths where tank pressure rises noticeably. Axes that reverse often also gain, because the pilot circuit then relieves cleanly.
