Total price
At 25 l/min any disturbance in the pilot circuit weighs more heavily than it would on a large step. Pilot oil is therefore drained externally here and held constant by a pressure reducing valve, while the supply stays internal.
Benefits
- 25 l/min nominal flow, fine resolution through the ±10 V command value.
- Internal pilot oil supply with external drain, so tank pressure has no effect.
- Pressure reducing valve in the pilot circuit for constant switching times at 315 bar.
- Concealed manual override for commissioning and fault situations.
- 8.43 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.
