Where a central control oil network exists, pilot pressure can be sized apart from working pressure. This valve uses external supply and external return, meters 50 l/min nominal flow up to 315 bar and accepts a ±10 V setpoint.

Total price
A central control oil network feeds many valves at once and keeps pilot pressure constant. The 4WRZE10W8-50-7X/6EG24N9K31/A1D3V is built for that, drawing pilot oil externally, draining it externally, and metering 50 l/min at up to 315 bar.
Benefits
- External piloting in supply and return, giving identical control behaviour on every valve fed by one control oil network.
- 50 l/min nominal flow, 170 l/min maximum throughput, operating pressure up to 315 bar.
- ±10 V setpoint, on-board electronics, 24 VDC supply.
- Mass 9.14 kg, spool symbol W8, 3 switching positions, 4 ports.
- ISO 4401-05-05-0-05 interface, FKM seals, HL hydraulic fluid.
