A 4 to 20 mA signal survives long cable runs without level loss and shows a wire break. The 4WRZE25W9-325 takes that command value and handles 325 l/min nominal flow. Size 25, 350 bar, weight 20.58 kg.

Total price
Twenty metres of cable between the control cabinet and the valve make a current signal the safer choice. The 4WRZE25W9-325 accepts a 4 to 20 mA command value and controls 325 l/min nominal flow with pilot oil supplied and returned through external lines.
Benefits
- Command value 4 to 20 mA, insensitive to voltage drop over long cables.
- 325 l/min nominal flow, up to 870 l/min in size 25.
- External pilot supply and external pilot return, pilot control stays fed even when the main circuit is unloaded.
- 350 bar operating pressure with FKM seals, hydraulic fluid HL.
- On-board electronics, 7-pole connector (6 + PE) to EN 175201-804.
- 20.58 kg weight, connection diagram ISO 4401-08-08-0-05.
