Ratings
Operating Temperature Range: 5 - 50°C (41 - 122 °F)
Maximum Operating Pressure1 150 psig (10 bar)
Differential Pressure Range:
3 - 860 sccm = 7 - 45 psid,
861 - 7200 sccm = 15 - 45 psid,
7201 - 50000 sccm = 25 - 45 psid
Typical pressure drop, high density gases like Argon gas applications require an additional 10 psid differential pressure
Leak Integrity (external): 1x10^-10 atm. cc/sec He
