Internal spool position feedback turns the valve into a closed control loop that compensates friction and flow forces. This 4WRTE25W6-350L-4X uses it at 350 l/min nominal flow, 350 bar and a 4 to 20 mA command value.

Without feedback the spool position drifts with temperature, friction and flow forces. The 4WRTE25W6-350L-4X measures spool position internally and corrects it continuously, at 350 l/min nominal flow and up to 870 l/min total flow.
Benefits
- Internal spool position feedback for high repeat accuracy
- 350 l/min nominal flow, 870 l/min maximum flow
- Spool symbol W6, three switching positions, four ports
- External pilot oil supply and external pilot oil return
- Analog 4 to 20 mA command value, on-board electronics, 350 bar operating pressure

Applications
Required in force and position control loops that must stay equally accurate over the full stroke, for example on materials testing machines and calibration presses. The external pilot circuit provides constant pilot pressure for this. Through ISO 4401-08-08-0-05 the valve is interchangeable with other size 25 types.
