Steering gear and deck cranes on board keep their pilot supply apart from the working circuit so the actuating function survives load changes. The 4WRZE10W8-85-7X/6EG24N9K31/A1M follows that layout with external supply and external return and regulates 85 l/min nominal flow through spool symbol W8.
Benefits
- External pilot oil supply and external return, separated from the main circuit.
- Nominal flow 85 l/min through spool symbol W8, maximum flow 170 l/min.
- Version without pressure reducing valve, concealed auxiliary actuation for emergency operation.
- Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05, size 10.
- Analog ±10 V command value, 24 VDC supply, weight 7.98 kg.
