On plants needing UKCA evidence, component selection tends to be the bottleneck. This pilot-operated proportional directional valve in size 25 covers that requirement while metering 220 l/min nominal flow at 350 bar operating pressure, with 870 l/min permitted as maximum flow.
Advantages
- UKCA evidence under electromagnetic compatibility regulation SI2016/1091.
- 220 l/min nominal flow at 350 bar, up to 870 l/min permitted.
- ±10 V command value at the on-board electronics through a 7-pole connector.
- External pilot oil supply plus external return keep the pilot stage clear of the working circuit.
- Concealed auxiliary actuation moves the axis during commissioning without any signal.
- FKM seals, 20.26 kg, on an ISO 4401-08-08-0-05 pattern.
