Butterfly valve

Butterfly Valve is an industrial valve used to regulate (open/close) flow in pipelines with various sizes. Due to its structure resembling a butterfly, it is commonly called a butterfly valve. The valve opens/closes the fluid by means of a disc that can rotate around its shaft at different angles. Typically, butterfly valves are operated by lever, handwheel, or actuators powered by electricity or pneumatic systems.
