When the main circuit runs unloaded at times, pilot control needs its own source. The 4WRZE25W9-325 is fed and relieved externally and handles 325 l/min nominal flow from a plus/minus 10 V command value. Size 25, 350 bar.

Total price
A pilot stage without pressure does not shift, so this valve takes its pilot oil from a dedicated line. The 4WRZE25W9-325 works with external supply and external return and controls 325 l/min nominal flow from a plus/minus 10 V voltage command.
Benefits
- External pilot supply and return, independent of the pressure state of the main circuit.
- Command value plus/minus 10 V, connects straight to common analogue outputs.
- 325 l/min nominal flow, up to 870 l/min in size 25.
- 350 bar operating pressure, FKM seals and hydraulic fluid HL.
- Pressure reducing valve in the pilot stage, concealed auxiliary actuation for service and commissioning.
- 20.5 kg weight, connection diagram ISO 4401-08-08-0-05.

Applications
Typical hosts are power units with accumulator charging or unloading circuits where system pressure drops within the cycle. The external pilot source keeps the valve ready during that phase. Mounting is on a subplate to ISO 4401 size 08.
