Compared with other valves, the butterfly valve has a simpler structure. It is smaller in size, lighter in weight, and has fewer components. It relies on several key components to form a butterfly valve, but it has achieved better use.

The butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switch, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline.

The double offset butterfly valve is further improved on the basis of a single eccentric butterfly valve. The structural feature is that the stem axis is eccentric from the center of the disc and from the center of the body.

Butterfly valves are like ball valves however have a few focal points. They are small and when activated pneumatically, they open and close rapidly. The plate is lighter than a ball, and the valve requires less structural backing than a ball valve of equivalent distance across.
