This variant separates pilot circuit from working circuit completely: pilot oil arrives externally, it drains externally. At 325 l/min nominal flow to 350 bar the spool follows a 4...20 mA current command, metering to spool symbol W6.

A dedicated pilot circuit holds pilot pressure steady even when working pressure collapses. That is what this build is made for, with external supply as well as external drain, 325 l/min nominal flow at a 870 l/min limit.
Benefits
- External pilot oil supply plus external drain, pilot pressure stays independent of working pressure
- 325 l/min nominal flow, 870 l/min flow limit, 350 bar operating pressure
- Current command 4...20 mA into on-board electronics, 24 VDC supply
- Spool symbol W6, 3 switching positions across 4 ports, concealed manual override
- FKM seals for HL fluid, UKCA to SI2016/1091, mass 20.58 kg
