A worm gear butterfly control valve is a mechanical device designed to regulate the flow of fluid in a variety of industrial applications. It uses a worm gear operating mechanism, consisting of a spiral worm and a worm gear with teeth, to control the movement of the valve. When the worm rotates, the worm wheel is driven to rotate, and the rotating motion is converted into linear or angular motion to operate the valve.
Favored for their lightweight, compact design and cost effectiveness, butterfly control valves are ideal for switching or regulating services. They feature a disk attached to the rod that opens when the disk rotates to allow fluid flow. The valve closes at a quarter turn so that the disc is perpendicular to the direction of flow.
