Total price
Many axis controllers output their command value as a voltage. The 4WRTE25W8-350L-4X/6EG24K31/A1V accepts that value directly as ±10 V and converts it into a spool position through the on-board electronics. At 350 l/min nominal flow and up to 870 l/min the pilot stage is fed and relieved through its own X and Y lines.
Benefits
- Analogue ±10 V voltage command value, usable directly with controllers that have an analogue output.
- 350 l/min nominal flow with a maximum flow rate of 870 l/min.
- External pilot oil supply and external return for a separated pilot stage.
- Closed loop W8 spool with three switching positions up to 350 bar.
- FKM seals, a valve weight of 18 kg and connection diagram ISO 4401-08-08-0-05.
