Spool symbol E1 with a ±10 V voltage command: the 4WRZE25E1-325 meters 325 l/min nominal flow, takes 870 l/min at peak and 350 bar. A pressure reducing valve in the pilot stage holds pilot pressure steady, pilot supply and return both run internally.

When system pressure swings with the machine cycle, the pilot stage suffers with it. The 4WRZE25E1-325-7X therefore carries a pressure reducing valve in its pilot stage and keeps pilot pressure constant while metering 325 l/min nominal flow at up to 350 bar.
Benefits
- Pressure reducing valve in the pilot stage decouples pilot pressure from system pressure.
- Nominal flow of 325 l/min, maximum flow 870 l/min.
- Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
- Internal pilot supply and internal return, no additional lines required.
- Spool symbol E1, three switching positions, four ports, NBR seals.
- Mass of 20.56 kg, connection diagram ISO 4401-08-08-0-05, UKCA declaration.

Application
The build is meant for plants under strongly varying load, such as presses on accumulator supply or power units running several axes at once. The pressure reducing valve keeps switching behaviour consistent there. NBR seals assume HL mineral oil within the usual temperature range.
