Full separation of the pilot circuit: this 4WRLE25W6-350LJ takes pilot oil from outside and drains it externally. It controls 350 l/min nominal flow at 350 bar, blocks the actuator ports at centre per symbol W6 and follows a 4 ... 20 mA current command.

Total price
Where main and pilot circuits must stay strictly separate, the version with external supply and external return is the right one. The 4WRLE25W6-350LJ-4X/MXY/24F1 works that way while moving 350 l/min nominal flow at 350 bar.
Benefits
- External pilot oil supply and external pilot oil return isolate the pilot circuit from both working pressure and tank pressure.
- 4 ... 20 mA current command flags a broken wire as a reading below 4 mA and stays stable over long distances.
- Spool symbol W6 keeps A and B blocked at centre, across 3 switching positions and 4 ports.
- 350 l/min nominal flow with reserve up to 1250 l/min, operating pressure 350 bar.
- CE conformity, valve mass 19.44 kg, mounting pattern ISO 4401-08-08-0-05.

Applications
Makes sense in plants with a dedicated pilot pump and strongly varying tank pressure, for example several axes running in parallel from one power unit. A fully external pilot circuit keeps switching times repeatable. The subplate has to provide both X and Y lines.
