The electric ball valve is composed of an electric actuator and a ball valve. It is a pipeline pressure element for industrial automation process control, usually used for remote opening and closing (connecting and cutting off the medium) control of pipeline media. The electric ball valve standard GB/T21465-2008 "Valve Terminology" defines it as: a valve in which the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Electric ball valves are divided into electric flange ball valves, electric wafer ball valves, electric welding ball valves, and electric threaded ball valves. According to the sealing form, it is also divided into soft-sealed electric ball valves and metal-sealed electric ball valves.
