If the power unit already holds a regulated pilot pressure, a second pressure reducing valve inside the valve is redundant. The 4WRZE16W8-180-7X/6EG24N9K31/F1V drops it, is fed as well as relieved externally and meters 180 l/min at 350 bar on a 4...20 mA command value.

Total price
Plants with their own pilot supply set control pressure centrally. This size 16 model is built for that case, doing without a pressure reducing valve of its own, at 180 l/min nominal flow, spool symbol W8 and operating pressure up to 350 bar.
Benefits
- No pressure reducing valve in the pilot circuit, control pressure arrives from the central supply.
- External pilot oil supply plus external return, independent of working pressure up to 350 bar.
- 180 l/min nominal flow against 460 l/min maximum flow.
- Command value 4...20 mA, supply 24 VDC, spool symbol W8 across 3 switching positions.
- FKM seals, mass 12.56 kg, mounting pattern ISO 4401-07-07-0-05, conformity UKCA.
