If port P does not carry pressure permanently, the pilot oil has to come from outside. The H-4WEH25D6X/6EG24N9TK4/B10 is fed externally, returns pilot oil internally and switches 700 l/min in size 25 at up to 350 bar.

Pilot-operated valves need reliable pilot pressure, otherwise the main spool does not shift. This version draws pilot oil from an external source and releases it internally into the tank passage, at flow up to 700 l/min.
Benefits
- External pilot oil supply for circuits where pressure at port P is missing at times.
- Internal pilot oil return, so no extra line to tank is required.
- Flow up to 700 l/min, maximum operating pressure 350 bar, spool symbol D.
- 4 ports and 2 switching positions on the ISO 4401-08-08-0-05 interface.
- 17.52 kg weight, NBR seals, 24 VDC supply voltage.

Application
Such circuits are found in presses with rapid traverse and load changeover, where system pressure drops for a moment. The valve still shifts because the pilot pressure comes from its own source. HL is the intended hydraulic fluid.
