Total price
A separate pilot oil circuit feeds this valve independently of what the main pump is currently delivering. The 4WRZE25W8-325-7X/6EG24N9TK31/F1M takes pilot oil in externally through port X, drains it internally to tank and releases 325 l/min nominal flow.
Benefits
- Pilot oil supply comes in externally through port X, independent of the main pump.
- Pilot oil return runs internally, with no extra external return line.
- 325 l/min nominal flow, up to 870 l/min possible through the valve.
- Operating pressure up to 350 bar, command signal 4 to 20 mA, 24 VDC supply.
- Spool symbol W8, three switching positions, weight 20.22 kg.
