A progressive characteristic instead of a linear one: the 4WRLE25W4-350SJ-4X opens flatly at small command values and much further at large ones. Nominal flow 350 l/min, up to 1250 l/min at peak, maximum operating pressure 350 bar, internal pilot routing.

Total price
Some axes have to creep in the fine range and still get the full cross section in rapid traverse. The 4WRLE25W4-350SJ-4X carries a progressive characteristic for that, translating small command values flatly and opening much wider at large ones.
Benefits
- Progressive characteristic gives fine resolution in the lower command range.
- Nominal flow of 350 l/min, maximum flow 1250 l/min.
- Internal pilot supply and internal return, X and Y lines fall away.
- Internal position feedback, spool symbol W4, three switching positions.
- Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
- Mass of 19.1 kg, NBR seals, maximum operating pressure 350 bar, CE conformity.

Application
The progressive characteristic suits handling axes, positioning with a creep speed and test sequences spanning a wide speed range. For control loops with fixed gain a linear build makes more sense. Connection diagram ISO 4401-08-08-0-05 matches size 25.
