Where a plant provides its pilot pressure centrally, the 4WRZE10W8-85-7X/6EG24K31/A1D3M works with fully external pilot routing. Supply through X, draining through Y, which decouples the pilot stage from pressure and return of the main circuit. 85 l/min nominal flow and 315 bar operating pressure are available.
Benefits
- External pilot supply and external draining, pilot pressure independent of working pressure.
- 85 l/min nominal flow, maximum flow up to 170 l/min.
- Voltage command value +/-10 V, on-board electronics with position feedback, 24 VDC.
- Operating pressure up to 315 bar, subplate mounting to ISO 4401-05-05-0-05.
- Spool symbol W8, 3 switching positions on 4 ports, weight 8.48 kg.
- NBR seals, hydraulic fluid HL, UKCA conformity.
