Not every plant needs separate lines for pilot oil supply and pilot oil drain. One external feed is enough here, and the drain goes internally into the tank gallery of the manifold. Controlled flow is 25 l/min nominal at 315 bar, held steady by a pressure reducing valve in the pilot circuit.
Benefits
- External pilot oil supply with internal drain, a single extra line is enough.
- 25 l/min nominal flow, up to 170 l/min maximum flow at 315 bar.
- Pressure reducing valve in the pilot circuit plus a concealed manual override.
- ±10 V command value on on-board electronics, 24 V DC supply.
- 9.22 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.
