Armstrong All Stainless Steel Free Floating Lever Air/Gas Vent 11-AV, 22-AV & 13-AV

The Armstrong All Stainless Steel Free Floating Lever Air Vents 

Have been developed to provide positive venting of air/gases under pressure.

The body and cap and all working parts of the No. 11-AV, 22-AV and 13-AV are made of high strength, corrosion resistant stainless steel. Body and caps are welded together to form a permanently sealed, tamperproof unit with no gaskets.
Elliptical floats and high leverage provide up to 115 SCFM capacity for these compact air/gas vents.
Lever action is guided to assure proper seating of the valve under all operating conditions.

11-AV, 22-AV and 13-AV—All stainless steel construction where exposure to either internal or external corrosion is a problem.
These air/gas vents have the same proven free floating mechanisms used in other Armstrong steam traps.
Pressures to 600 psi @ 100°F (41 bar @ 38°C).
