Total price
When replacing a valve, what counts most is that spool symbol and pilot routing match the existing manifold. The 4WRZE25E325-7X works with symbol E, internal pilot supply and an external drain, metering 325 l/min nominal flow.
Benefits
- Nominal flow of 325 l/min, maximum flow 870 l/min in size 25.
- Internal pilot supply with an external drain through the Y port.
- Pressure reducing valve in the pilot stage keeps pilot pressure constant.
- Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
- Spool symbol E, three switching positions, concealed manual override.
- Mass of 20.62 kg, NBR seals, maximum operating pressure 350 bar.

Application
The valve fits manifolds that already have a Y port, for instance when replacing older series. Internal pilot supply makes a separate X line unnecessary. Connection diagram ISO 4401-08-08-0-05 and the UKCA declaration to SI2016/1091 are documented.
