Armstrong model 22AV all stainless steel air vent with a 3/4" NPT connection for service up to 35 psi. The 22AV provides positive venting of air/gases under pressure. The vent's body and caps are welded together to form a permanently sealed, tamperproof unit with no gaskets. Elliptical floats and high leverage enable the 22AV to provide a capacity up to 115 SCFM. Lever action is guided to ensure proper seating of the valve under all operating conditions. The vent features the same free-floating mechanisms used in other Armstrong steam traps.
