Total price
Axes that work very finely at low command values and need plenty of oil at high ones benefit from a progressive characteristic. The 4WRLE25E350SJ-4X/MXY/24A1 pairs that curve with 350 l/min nominal flow at 350 bar.
Benefits
- Progressive characteristic, small commands give small opening steps while large ones release the full cross section.
- Pilot oil supplied and drained externally, making the pilot circuit independent of working and tank pressure.
- 350 l/min nominal flow, up to 1250 l/min maximum flow, operating pressure 350 bar.
- Spool symbol E on 4 ports with 3 switching positions, ±10 V command.
- CE conformity, 18.58 kg valve mass, mounting pattern ISO 4401-08-08-0-05.

Applications
Suited to positioning and infeed axes that creep away from standstill and then travel briskly, for example on manipulators and forming machines. The external pilot circuit requires X and Y lines at the subplate. In return, switching times stay independent of what the main circuit is doing.
