Where the axis should receive oil immediately out of centre, spool symbol W8 fits. The 4WRKE27W8-500P-3X supplies 500 l/min nominal flow, copes with 1000 l/min and draws its pilot oil externally, at 270 bar.

The choice of spool symbol decides how the axis behaves at standstill. The 4WRKE27W8-500P-3X uses spool symbol W8, releases 500 l/min nominal flow and works with external pilot supply and external drain on a 4...20 mA current command value.
Benefits
- Spool symbol W8 in three switching positions for cylinders that start quickly out of centre.
- 500 l/min nominal flow and up to 1000 l/min total flow in size 27.
- External pilot oil supply and drain keep pilot control independent of working pressure.
- A 4...20 mA current command value with on-board electronics on a 24 VDC supply.
- 270 bar operating pressure at 19.5 kg, laid out for continuous duty on large units.
- NBR seals and HL hydraulic fluid as the usual pairing in mineral oil service.
