G1/4-G3/8
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.
Fluid: Compressed air
Maximum pressure solenoid operated: Dependent on solenoid
rating. Must not exceed 17 bar (250 psig).
Maximum pressure pilot operated: 17 bar (250 psig) max.
Minimum operating pressure: 3 bar (44 psig)
Operating temperature solenoid operated: Dependent on solenoid
rating. Must be within range -20°C* to +65°C (0°F* to +150°F).
Operating temperature pilot operated:
-20°C* to +65°C (0°F* to +150°F)
* Air supply must be dry enough to avoid ice formation at temperatures below +2°C
(+35°F).
Air Pilot Port:
10-32 UNF with PTF main ports
M5 with ISO main ports
Exhaust Port:
1/4" PTF with PTF main ports
Rc1/4 with ISO G and ISO Rc main ports
Typical flow with 6,3 bar (90 psig) inlet pressure and pressure
drop of 0.5 bar (7 psig):
21 dm3/s (45 scfm) [P1 to P2 = Cv 1,59] [P2 to P3 = Cv 1,72]
Snap pressure: Full flow when downstream pressure reaches
50 – 80% of inlet pressure
Charge time for 2 litre (0.53 gallon US) downstream volume and
6,3 bar (90 psig) inlet pressure:
Minimum 0,8 sec.
Typical maximum 99 sec.
