1/2/3/6-AV Series Free-Floating Lever Air/Gas Vents—Cast Iron


For pressures to 300 psig (21 bar) or specific gravity down to 0.40

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

2-AV, 3-AV and 6-AV—These cast iron vents use the same proven free-floating lever mechanisms used in Armstrong steam traps. They are for applications where high air/gas venting capacity is required, up to 250 psi (17 bar).
