AVT125 Air Vents

AVT125 series (Thermostatic Air Vents) are used on steam applications up to 125 PSIG for removal of air and non-condensable gases from process equipment, vessels and piping. The air vent contains a welded stainless steel thermal element that expands when heated and contracts when cooled. When air and non-condensable gases are present, the valve is in the open discharge position. When steam reaches the air vent, the element expands and closes the valve off tightly. The air vent should be located at the highest paint in the system or vessel.

Description

The AVT125 is used on steam applications up to 125 PSIG for removal of air and non-condensable gases. Use on process equipment, vessels, and piping. The air vent should be located at a high point in the system or vessel and can be installed in any orientation.

The thermostatic air vent contains a welded stainless steel thermal element that expands when heated and contracts when cooled. When air and non-condensable gases are present, the valve is in the open discharge position. When steam reaches the air vent, the element expands and closes the valve off tightly.
