A 4 to 20 mA command also reports a broken wire, because anything below 4 mA is no valid signal. This size 25 version uses that property, meters 350 l/min nominal flow at up to 350 bar and works with spool symbol W6.

A current command brings diagnosis along with it, since a cut cable results in 0 mA instead of an apparently valid value. The 4WRTE25W6-350L-4X/6EG24EK31/F1M is steered that way and meters 350 l/min nominal flow at an operating pressure of up to 350 bar.
Benefits
- Command value 4 to 20 mA, a broken wire shows up as loss of current
- 350 l/min nominal flow in size 25, up to 870 l/min with the corresponding pressure drop
- Internal pilot oil supply with external return, operating pressure up to 350 bar
- Spool symbol W6 with three switching positions across four ports, internal spool position feedback
- 17.92 kg weight, NBR seals for HL hydraulic fluid, connection diagram ISO 4401-08-08-0-05
