Technical data
System air supply:
Turn on system air supply prior to applying pilot signal to operator.
Failure to do so may cause valve to continuously exhaust.

Dependent on solenoid rating. Must not exceed 17 bar
Maximum pressure pilot operated:
17 bar max.
Minimum operating pressure:
3 bar
Operating temperature solenoid operated:
Dependent on solenoid rating. Must be within range -20°C to +80°C
Consult our Technical Service for use below +2°C
