A 4 to 20 mA current signal reports a broken wire by itself, because 0 mA is not a valid value. The 4WRLE27W8-430LJ-4X uses that interface, controls 430 l/min in size 27 and works up to 270 bar. Symbol W8, 20.12 kg.

Over long cable runs a current loop is the more robust choice. The 4WRLE27W8-430LJ-4X/MXY/24F1 takes its command value as 4 to 20 mA and turns it into 430 l/min nominal flow, at up to 1850 l/min maximum flow.
Benefits
- Command value 4 to 20 mA, a broken wire shows up in the signal itself.
- 430 l/min nominal flow in size 27, up to 1850 l/min flow.
- Symbol W8 with a defined overlap, three switching positions.
- 270 bar operating pressure, connection diagram ISO 4401-08-08-0-05.
- External pilot oil supply plus external return, constant pilot pressure.
- 20.12 kg, NBR seals, CE conformity, on-board electronics.

Applications
The valve suits sprawling plants where cabinet plus valve manifold sit dozens of metres apart. A current loop stays stable there, and a cable fault produces a recognisable signal rather than a seemingly valid zero.
