When a large axis is rebuilt, the subplate is often already drilled and should stay that way. This size 25 valve accommodates that by supplying and returning pilot oil internally while metering 350 l/min nominal flow.
Benefits
- 350 l/min nominal flow without the additional X and Y lines at the plate.
- Peak flow up to 870 l/min for fast return and rapid traverse.
- ±10 V command value at the on-board electronics, supply voltage 24 VDC.
- FKM seals for installations with high oil temperature and long duty cycles.
- Interface ISO 4401-08-08-0-05, spool symbol W8, weight 18 kg.

Applications
The version makes sense in upgrades of large presses and test cylinders where an existing plate is kept. Dropping the pilot pipework shortens downtime noticeably. Before fitting, check that pressure in port P covers the pilot demand throughout the cycle.
