When only an external drain line is free of back pressure, the pilot circuit has to relieve there. The 4WRZE16W6-180-7X/6EG24N9EK31/F1D3V supplies itself internally, returns externally and meters 180 l/min at 350 bar, command value 4...20 mA, spool symbol W6.

High back pressure in the tank line throws pilot-operated valves off balance. This build of the size 16 model therefore relieves its pilot circuit through a separate external path while still feeding itself internally, at 180 l/min nominal flow and operating pressure up to 350 bar.
Benefits
- Internal supply with external pilot oil return keeps the control circuit clear of tank back pressure.
- 180 l/min nominal flow against 460 l/min maximum flow.
- Pressure reducing valve in the pilot circuit caps control pressure under 350 bar working pressure.
- Command value 4...20 mA at the on-board electronics, supply 24 VDC.
- Spool symbol W6, FKM seals, mass 12.12 kg, mounting pattern ISO 4401-07-07-0-05.
