Air Vent applications are to eliminate trapped air in the pipe line or tank. It is installed in highest position in pipe line or tank. The valves prevent the pipe line from vibration in first operation and allowing the trapped air come out from pipe line. The valve will open if there is an air flow and will closed when liquid reached the valve.

Working Principle

Valve open

The air trapped in the valve, when liquid level rise, the ball float and allowing the air out of the valve until there is no air in the valve and the ball blocked the top seat to preventing liquid from leaking.

Valve closed

In vacuum condition, the ball block the bottom seat to prevent air came into pipeline
