Total price
When an axis has to stay put in mid position, the spool symbol decides. The 4WRKE27E500L-3X closes all four ports with symbol E and still meters 500 l/min nominal flow at 270 bar as soon as a command value arrives.
Benefits
- Symbol E - all 4 ports blocked in mid position, so the axis holds without a separate circuit.
- 500 l/min nominal flow at 270 bar, up to 1000 l/min maximum.
- Internal spool position feedback with on-board electronics, ±10 V command on 24 VDC.
- Internal pilot supply, external pilot drain through a dedicated Y line.
- 19.28 kg, NBR seals, mounting pattern ISO 4401-08-08-0-05, HL hydraulic fluid.

Application
Intended for size 27 axes that must not drift when de-energised or at zero command, vertical press axes among them. A blocked spool is not a substitute for load holding valves under the safety standards. Suspended loads still need their own protection.
