Butterfly air valve

Butterfly air valves are crucial devices employed in a variety of industries to regulate the flow of air. By learning how these valves work, we can see why Huagong's Butterfly valves are so crucial to keeping things in balance


A butterfly air valve is somewhat like a door that opens and closes to let air in or out. It consists of a rotating, flat disc that is turned by a crank or lever. When the disc is in its profile, or sideways, position, it shuts off the air. When the book is oriented upright, the air is free to pass through.

How a butterfly air valve regulates airflow

We can determine how much air flow is allowed by rotating the disc in the butterfly air valve. If we want more air, we can open the valve still more. If we want less air, we partially close the valve. This enables us to adjust the air flow according to the demand of the equipment or machines running on compressed air.
