- 100 l/min nominal flow and 170 l/min maximum flow.
- Spool symbol W6 with three switching positions and a linear curve with fine control range.
- External pilot oil supply and external return, matching existing control piping.
- 315 bar maximum operating pressure, 8.38 kg weight, ±10 V command at 24 VDC.
