Armstrong 3/4" 11AV stainless steel air vent with a 178 psi maximum operating pressure. Armstrong all-stainless steel guided lever air vents provide positive venting of air/gases under pressure. The body and cap and all working parts of 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 enable these compact air/gas vents to provide a capacity up to 115 SCFM (195 m3h). Lever action is guided to ensure proper seating of the valve under all operating conditions. All stainless steel construction provides protection 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. These vents are suitable for pressures up to 600 psi at 100°F.
