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 medium) control of pipeline medium. It is mainly used to cut off or connect the medium in the pipeline, and it can also be used for the regulation and control of the fluid. Among them, there is a strong shear between the V-shaped ball core of the hard-sealed V-type ball valve and the metal valve seat of hard-facing carbide. Shearing force, especially suitable for media containing fibers and tiny solid particles. 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 seal electric ball valve and hard seal electric ball valve.
