1AV - 3/4" NPT, 7/64" Orifice, 173 PSI, Cast Iron Air Vent

Armstrong free-floating lever air/gas vents use the same bodies, caps, lever mechanisms, valve and seats of Armstrong inverted bucket steam traps that have been proved in years of service.

Elliptical floats and high leverage make it possible to open large orifices to provide adequate capacity for vent size and weight. The hemispherical valve, seat and leverage are identical in design, materials and workmanship to those for saturated steam service up to 1,000 psig (69 bar), with the exception of the addition of a guidepost. The guidepost has been added to ensure a positive, leaktight valve closing under all conditions.

The 1-AV is a cast iron air vent that uses a free-floating lever that closes positively, ensuring a leak-tight closing under all conditions. This vent is good for low capacity air/gas venting up to 300 psi (21 bar).
