Metering finely around zero and still travelling quickly beyond it calls for a progressive characteristic. This size 25 4WRLD works up to 280 bar operating pressure at 400 l/min nominal flow and draws its pilot oil internally. The digital axis controller is already built into the valve.

Total price
Creep and positioning moves are decided by resolution around centre, while rapid traverse needs full flow. The 4WRLD25E350SJ-4X/MPY/24ND6T combines both through its progressive characteristic and meters 400 l/min nominal flow at up to 280 bar operating pressure.
Benefits
- Progressive characteristic - high resolution around centre and full throughput at stroke end, three switching positions.
- Internal pilot oil supply with external pilot oil return, which removes the need for a separate pilot pressure line.
- 400 l/min nominal flow in size 25, up to 1250 l/min by design.
- 280 bar operating pressure, rated for HL hydraulic fluid with NBR seals.
- Digital axis controller on board, command value analog ±10 V through a 12-pole connector (11 + PE).
