All Dimensions in Inches (mm)
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:
Dependant on solenoid rating
[must not exceed 250 psig (17 bar)]
Maximum pressure pilot operated: 250 psig (17 bar) max.
Minimum operating pressure: 44 psig (3 bar)
Operating temperature solenoid operated:
Dependant on solenoid rating
[must be within range 0°* to 150°F (-20°* to 65°C)]
Operating temperature pilot operated:
0°* to 150°F (-20°* to 65°C)
* Air supply must be dry enough to avoid ice formation at temperatures below 35 ° F (2 ° C).
Air Pilot Port:
10-32 UNF with PTF main ports
M5 with ISO main ports
Exhaust Port:
1/4" PTF with PTF main ports
1/4" ISO Rc with ISO Rc main ports
1/4" ISO Rc with ISO G main ports
Maximum flow with 90 psig (6.3 bar) inlet pressure and pressure drop of 7 psig
(0.5 bar): 45 scfm (21 dm 3 /s) [P1 to P2 = Cv 1.59] [P2 to P3 = Cv 1.72]
