Total price
A size 10 actuator is driven here at 50 l/min nominal flow. Internal pilot oil supply and internal return mean the manifold only has to carry the four main bores and the mounting threads to ISO 4401-05-05-0-05.
Benefits
- Fully internal pilot stage, the manifold needs only the four main bores
- 50 l/min nominal flow and 170 l/min maximum flow
- Spool symbol W9, 3 switching positions, operating pressure up to 315 bar
- ±10 V analogue command at the on-board electronics, 24 VDC supply
- NBR seals, HL hydraulic fluid, weight 8.46 kg
