Total price
When converting a manifold there is rarely room for new bores. The 4WRZ25E220-7X/6EG24N9ETK4/D3V therefore uses the existing P and T channels for its pilot stage and meters 220 l/min of rated flow.
Benefits
- Rated flow of 220 l/min in size 25, with up to 870 l/min across the valve.
- Internal pilot oil supply and internal pilot oil return on the pilot-operated main stage.
- Spool symbol E with three switching positions across four ports.
- Integrated pressure reducing valve in the pilot path for repeatable switching behaviour.
- 20.38 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.
