A 4 to 20 mA current loop can be diagnosed, a voltage input cannot. The 4WRZE25W9-325-7X/6EG24N9ETK31/F1D3V works on one, controls 325 l/min nominal flow in size 25 and routes pilot oil internally. Weight 20.85 kg.

When a signal cable fails, the control should notice before the axis stops. The 4WRZE25W9-325-7X/6EG24N9ETK31/F1D3V therefore takes its command value as 4 to 20 mA while controlling 325 l/min nominal flow at up to 870 l/min maximum flow.
Benefits
- Command value 4 to 20 mA, a missing signal is distinguishable from a valid zero.
- 325 l/min nominal flow, 870 l/min maximum flow.
- Internal pilot oil supply plus internal return, a leaner manifold.
- Symbol W9 with a pressure reducing valve in the pilot stage, 350 bar operating pressure.
- FKM seals, connection diagram ISO 4401-08-08-0-05, UKCA evidence SI2016/1091.
- 20.85 kg, concealed manual override for commissioning.
