Where a dedicated pilot oil supply already exists, a valve can use it for supply and return alike. The 4WEH16R7X/6EG24N9K4/B10 is built that way and switches three positions to symbol R at 300 l/min and up to 280 bar operating pressure.

Both pilot oil paths of this valve lie outside the working circuit. Switching therefore stays the same even when the working pressure collapses during the cycle, at a rated flow of 300 l/min.
Benefits
- External supply and external return, so pilot pressure and pilot return are decoupled from the working circuit.
- Three switching positions to symbol R across four ports.
- 300 l/min at up to 280 bar, weight 9.84 kg.
- Subplate mounting to ISO 4401-07-07-0-05, the valve sits on the subplate without an adapter.
- Solenoid for 24 VDC with a 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL hydraulic fluid, 9.84 kg in weight.
