Endurance tests on large components run for hours, and any drift in the actuator falsifies the result. The 4WRKE25E350L-3X/6EG24K31/A1D3V holds the command at 350 l/min rated flow and 350 bar maximum and corrects the spool through internal feedback.
Benefits
- Internal piston position feedback with a linear characteristic, drift is corrected continuously.
- 350 l/min rated flow, flow up to 870 l/min, operating limit 350 bar.
- Spool symbol E, three switching positions, size 25 to ISO 4401-08-08-0-05.
- External pilot oil supply and external pilot oil return, a separate pilot circuit is possible.
- Command value 10 V bipolar, 24 VDC supply, 17.9 kg, FKM seals, HL fluid.

Application
Component and structural test rigs, rotor blade testing and large cylinder testing use the valve in a position or force loop. A separate pilot circuit allows finer filtration for the pilot stage than for the main flow. For axes that need a blocked centre, symbol W6 is available.
