In a steel plant the cabinet often sits dozens of metres from the valve. This size 25 unit therefore takes 4 to 20 mA as command value while metering 325 l/min nominal flow at 350 bar. Spool symbol W8, pilot oil external on both sides.

A 4 to 20 mA current signal loses no accuracy over long cable runs, which is exactly how this pilot-operated proportional directional valve in size 25 works at 325 l/min nominal flow with 350 bar operating pressure.
Advantages
- 4 to 20 mA command value stays stable over long cabling, even alongside frequency converters.
- 325 l/min nominal flow at 350 bar, 870 l/min maximum.
- External pilot oil supply plus external return give constant pilot conditions.
- Concealed auxiliary actuation moves the axis with no electrical control applied.
- FKM seals at 20.2 kg, tested to the UKCA rule on electromagnetic compatibility.
