Where the pilot stage has to run on its own control oil supply, the valve needs an external pilot inlet and an external pilot drain. This size 10 unit meters 85 l/min nominal flow at up to 315 bar operating pressure and takes a 4 to 20 mA current command.

A separate pilot oil circuit calls for a valve that draws and drains its pilot oil externally. This size 10 proportional directional valve is built that way and meters 85 l/min nominal flow at up to 315 bar operating pressure.
Benefits
- External pilot oil supply and external pilot oil return keep the pilot pressure clear of the main circuit.
- 85 l/min nominal flow, maximum flow 170 l/min, maximum operating pressure 315 bar.
- Command value 4 to 20 mA as an impressed current, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
- Spool symbol E, 3 switching positions, 4 ports, subplate mounting to ISO 4401-05-05-0-05.
- Weight 8.45 kg, FKM seals, rated for HL hydraulic fluid.

Applications
The design suits manifolds whose pilot oil comes from a dedicated pump or an accumulator. Pilot supply then stays available while pressure in the main circuit swings. A 4 to 20 mA current command also tolerates long cable runs between control cabinet and valve.
