When flow runs short but the subplate should stay, this valve brings 350 l/min at up to 350 bar on the unchanged ISO 4401-08-08-0-05 pattern. Spool symbol E1 with internal position feedback takes a plus or minus 10 V command. Pilot oil is fed in and returned externally.

Total price
When flow no longer suffices but the subplate should stay in place, a larger nominal flow on the same hole pattern solves it. The 4WRTE25E1-350P-4X/6EG24K31/A1M delivers 350 l/min at up to 350 bar on ISO 4401-08-08-0-05 and controls the spool through internal position measurement.
Benefits
- 350 l/min nominal flow on an unchanged ISO 4401-08-08-0-05 mounting pattern.
- Spool symbol E1 with a fine control range keeps small commands resolvable despite the large nominal flow.
- Internal spool position feedback gives high repeat accuracy up to 350 bar.
- External pilot oil supply and external return separate pilot oil from working pressure.
- Plus or minus 10 V command, 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804, weight 18 kg.

Applications
The valve serves press cylinders, hoists and clamping axes whose cycle time is limited by flow. Range maximum flow reaches 870 l/min, so 350 l/min leaves headroom. NBR seals and HL fluid match ordinary mineral oil operation.
