Running a large size 27 axis under position control calls for a valve that reports its own spool position. The 4WRKE27W6-500L meters 500 l/min nominal flow at 270 bar and corrects the spool itself. Pilot oil is drawn internally, the pilot drain leaves the valve externally.

On a position-controlled axis, what counts is whether the spool truly sits where the command sends it. The 4WRKE27W6-500L-3X measures its spool position internally and trims it, while metering up to 500 l/min nominal flow at 270 bar.
Benefits
- 500 l/min nominal flow at 270 bar operating pressure, peaks up to 1000 l/min.
- Internal spool position feedback - the on-board electronics correct positional error without an outer control loop.
- Command value ±10 V on a 24 VDC supply, wired through a 7-pole connector (6 + PE) to EN 175201-804.
- Symbol W6 with 3 switching positions and 4 ports, mounting pattern ISO 4401-08-08-0-05.
- Internal pilot supply, external pilot drain - the pilot circuit stays clear of back pressure in the tank gallery.

Application
A fit for presses, test rigs and injection moulding machines where a size 27 axis is controlled by position or speed. The external drain requires a dedicated Y line to tank. That pays off wherever the tank gallery carries back pressure, because the pilot stage then stays independent of it.
