Long signal runs in a plant do not tolerate voltage commands. This build therefore takes a current command of 4...20 mA to meter 325 l/min at 350 bar. Pilot oil is supplied internally as well as drained internally, spool symbol is W6.

A 4...20 mA current command makes control of this valve immune to voltage drop over long cable runs. Behind it works a pilot-operated main spool rated 325 l/min nominal flow, 870 l/min flow limit at 350 bar operating pressure.
Benefits
- Current command 4...20 mA, insensitive to cable length as well as electrical noise
- 325 l/min nominal flow at 350 bar, flow limit 870 l/min
- Pilot oil supplied internally, drained internally, no extra piping needed
- Spool symbol W6 with 3 switching positions, concealed manual override
- FKM seals for HL fluid, UKCA to SI2016/1091, size 25 at 20.58 kg
