In this build the 4WRZE25W8-220 draws pilot oil internally and drains it externally. At 220 l/min nominal flow, 350 bar operating pressure and a 4 ... 20 mA command, switching time stays stable even at high tank back pressure.

When the shared return line of a plant carries pressure, the switching time of pilot-operated valves grows noticeably. The 4WRZE25W8-220-7X/6EG24EK31/F1D3M avoids this through external pilot oil return while metering 220 l/min nominal flow.
Benefits
- External pilot oil return keeps shifting time independent of pressure in the working return.
- Internal pilot oil supply is enough while system pressure is present and saves one line.
- A 4 ... 20 mA command for long signal runs in large installations.
- 220 l/min nominal flow, 870 l/min maximum flow, spool symbol W8.
- Integrated pressure reducing valve, on-board electronics, mass 20.8 kg.
