Total price
Large axes on a shared pilot oil supply need a valve that handles 325 l/min and brings the pilot circuit fully outside. This version does both and takes the command value as a 4-20 mA current.
Benefits
- 325 l/min nominal flow, valve maximum 870 l/min, operating pressure up to 350 bar
- External pilot feed and external return for centrally supplied pilot circuits
- 4-20 mA command value, suited to long cable routes between cabinet and valve
- Spool symbol W6, three switching positions, four ports
- Mass 20.58 kg, subplate mounting ISO 4401-08-08-0-05, FKM seals
