Air Vents

Armstrong air vents remove trapped air and non-condensable gases from steam and hydronic systems, improving heat transfer efficiency and preventing air binding. Available in thermostatic balanced-pressure designs (TV-2 for pressures to 125 psig, TS-2 to 50 psig) and compact float-type models (AV-11, AV-13) for hydronic heating, cooling, and liquid service to 150 psig.
