What is an Auto Air Vent Valve?

Auto Air Vent Valve is designed for use on heating systems.

How does an Auto Air Vent Valve work?

Auto Air vent valve is a device for bleeding air from the pipeline system. It is based on the principle of a float. The float floats, pressing the needle or plug against the outlet. The air from the heating or water supply system rises up, the float drops, opening the outlet. As soon as the air was out, the float floated up again and blocked the exit. From this, these products are called automatic air vents or air valves. True, there are also air valves in the sewer system, but they perform a different function there.
