The spool symbol decides how an axis behaves in mid position and therefore belongs to the safety assessment. This size 25 valve uses the E spool, takes a ±10 V command and meters 350 l/min at 350 bar through an externally supplied pilot circuit.

Total price
Choosing a directional valve often starts with the spool symbol rather than with any other figure. The 4WRDE25E350L-6X/MXYWG/24A5 is built around the E spool, receives pilot oil externally through X and Y and meters 350 l/min at 350 bar from a ±10 V command.
Benefits
- E spool in size 25 with three switching positions and four ports.
- 350 l/min nominal flow at 350 bar, the body limit stands at 870 l/min.
- External pilot circuit through X and Y, independent of the working pressure of the axis.
- ±10 V command with on-board electronics on a 24 V DC supply.
- 17.5 kg on the ISO 4401-08-08-0-05 interface, NBR seals.
