Total price
When a fast axis calls for a symbol with different control edge ratios, W6 is the choice. The 4WRZ25W6-325-7X/6EG24N9K4/D3V brings that symbol together with 325 l/min of rated flow and runs a fully external pilot oil circuit.
Benefits
- Rated flow of 325 l/min in size 25, with up to 870 l/min across the valve.
- External pilot oil supply and external pilot oil return on the pilot-operated main stage.
- Spool symbol W6 with three switching positions across four ports.
- External electronics, the card stays in the cabinet and is reachable without removing the valve.
- 20.36 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.
