A butterfly control valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a Ball Valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

A butterfly valve is from a family of valves called quarter-turn valves.


ZSHWB Series of Double Eccentric Butterfly Valve(High performance butterfly valve), both valve disc and sealing ring are designed in special eccentric structure, with characteristics of impact structure, good shut-off performance, repair and replace conveniently and long operation life, so it has both regulating and shut-off functions, which could be widely used to cut off and regulate the processing fluids, such as metallurgy, oil, chemical engineering, electric power, natural gas.
