This build combines a fully external pilot circuit with the 4 to 20 mA current interface. The pair makes sense in accumulator operation, where system pressure and the electrical environment are both restless. Nominal flow is 350 l/min at up to 350 bar.

Total price
In accumulator operation system pressure swings considerably between charge and discharge. The 4WRLE25W8-350LJ-4X/MXY/24F1 therefore draws pilot oil externally through X and discharges it through Y, so the pilot stage works independently and holds 350 l/min under control.
Benefits
- External pilot supply and external return leave the pilot stage untouched by charge and discharge pressure
- Command value 4 to 20 mA, immune to voltage drop on long cables
- 350 l/min nominal flow with a maximum of 1250 l/min in size 25
- Internal spool position measurement for reproducible metering areas
- Spool symbol W8, three switching positions, four ports, operating pressure 350 bar
- Mass 19.38 kg, CE conformity, NBR seals
