Total price
Two influences distort a small command value particularly easily: voltage drop along the cable and back pressure at the pilot stage. This version rules both out, with a 4...20 mA command value and an external pilot drain at 25 l/min nominal flow.
Benefits
- 25 l/min nominal flow at 315 bar, reserve up to 170 l/min.
- 4...20 mA command value, independent of cable length and terminal voltage.
- Internal pilot oil supply with external drain, no back pressure on the pilot stage.
- Pressure reducing valve in the pilot circuit, concealed manual override.
- 8.46 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.
