A return line under back pressure distorts the pilot stage and costs accuracy. The 4WRZE32E520-7X/6EG24N9EK31/F1V takes its pilot oil internally and discharges it externally through a dedicated port, at 520 l/min nominal flow with spool symbol E.
Benefits
- Internal pilot oil supply with external pilot oil return, piloting free of back pressure
- 520 l/min nominal flow, maximum flow 1600 l/min
- Setpoint 4 to 20 mA for long signal runs
- Spool symbol E, maximum operating pressure 350 bar in size 32
- Concealed auxiliary actuation, version without pressure reducing valve
- FKM seals for HL, 44 kg weight, UKCA conformity

Applications
Useful wherever the shared tank return carries pressure, for example with filter and cooling circuits in the return line. The separate pilot drain routes the pilot stage past that counterforce. Typical applications are large presses and rolling mill axes.
