On manifolds with their own pilot circuit the pilot oil comes from outside. In the 6EG24K31 version the 4WRKE27W6-500L takes both pilot supply and pilot drain externally and meters 500 l/min nominal flow at 270 bar through symbol W6.

A separately fed pilot circuit keeps pilot pressure steady even when working pressure collapses. In this version the 4WRKE27W6-500L-3X draws its pilot oil externally and drains it externally, while metering 500 l/min nominal flow at 270 bar.
Benefits
- External pilot supply and external drain - pilot pressure stays independent of the pressure in the P gallery.
- 500 l/min nominal flow, up to 1000 l/min, operating pressure to 270 bar.
- Symbol W6, 3 switching positions, 4 ports, mounting pattern ISO 4401-08-08-0-05.
- Internal position feedback and on-board electronics, ±10 V command on 24 VDC.
- 19.32 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Application
Worth choosing where working pressure swings widely or drops below the pilot pressure the valve needs. A separate pilot pump then supplies the reserve. The manifold has to provide both an X and a Y gallery for it.
