Armstrong Automatic Air Vent Valve

Air vent models av 11 and av 13 are compact float type valves for the removal of air and other gases from hydronic heating and cooling systems liquid chilling operations and other light liquid services.

Armstrong automatic air vent valve.

Armstrong offers compact versatile air vents for hot or cold water that automatically purge unwanted air from installations allowing your system to run more efficiently. The design of the 11av is very simple. Hydronic system air vents. Armstrong ava and avv automatic air vents continuously remove air that can accumulate in a hydronic system.

Minimal liquid carry over. Av 11 av 13 air vents for pressures to 150 psig 10 bar physical data model av 11 av 13 connection size in mm in mm in mm. Elimination helps to reduce system operating noise caused by entrained air in the hydronic fluid and also helps to extend system. 21 ar and 21 312ar var fixed pivot ball float air gas vents for pressures to 600 psig 41 bar or specific gravity down to 0 83 21 ar a small economical air vent of high quality.

It employs a float which actuates a guided free. It employs a float which actuates a guided free floating valve there are no pivots to wear or create friction that could interfere with the correct operation of the vent valve and the lever guide positive closure under as. The air vents can handle gas removal from liquids with specific gravities as low as 0 40 and pressure to 2 700 psi 186 bar. The armstrong i i av automatic air vent valve designed to combine the durability and corrosion resistance of stainless steel with a to produce a highly reliable vent valve in the medium capacity air venting range the of is very simple.

Armstrong offers thermostatic air vents for positive venting of air and other non condensable gases from steam in chamber type heat transfer equipment. Armstrong air vents are ideally suited for this purpose. The float operated design means the vents can instantly and automatically adjust to variations in gas flow and pressure. Component life by reducing the risk of corrosion or cavitation.

Armstrong air vents are ideally suited for this purpose. Pick up an efficient air vent or enhanced inline air separator from grainger to help remove 99 of extraneous air from hydronic heating systems. The air vents can handle gas removal from liquids with specific gravities as low as 0 40 and pressure to 2 700 psi 186 bar. The float operated design means the vents can instantly and automatically adjust to variations in gas flow and pressure.

150 psi automatic air vent valve brass 1 2 in inlet. 21 312 ar var forged steel version of the model 21 with a larger float and higher leverage. 178 psi float type air vent stainless steel 3 4 in inlet. Typical applications include jacketed kettles retorts vulcanizers jacketed sterilizers or other contained equipment where air could accumulate in remote areas of the steam chamber and reduce heat transfer capacity.
