Turbine and valve hydraulics often draw pilot oil from a filtered bypass line while the return stays inside the manifold. The 4WRZE10E1-85-7X/6EG24N9TK31/F1M is built exactly that way and regulates 85 l/min nominal flow through spool symbol E1 up to 315 bar operating pressure.
Benefits
- External pilot oil supply combined with internal pilot oil return.
- Nominal flow 85 l/min, maximum flow 170 l/min, size 10.
- Spool symbol E1 with three switching positions, connection diagram ISO 4401-05-05-0-05.
- Version without pressure reducing valve, concealed auxiliary actuation on the pilot valve.
- Current command 4...20 mA, 24 VDC supply, weight 8.48 kg.
