Two measures raise repeatability noticeably: a pilot drain free of back pressure and a command value transmitted as a current. Both are combined here, at 50 l/min nominal flow with spool symbol W8.
Benefits
- 50 l/min nominal flow at 315 bar, reserve up to 170 l/min.
- Internal pilot oil supply, external drain free of back pressure from the tank gallery.
- 4...20 mA command value, insensitive to cable length and interference fields.
- Pressure reducing valve in the pilot circuit, concealed manual override.
- 8.46 kg weight, spool symbol W8, 3 switching positions, NBR seals.
