Electric ball valve consists of electric actuators and valves electric ball valve.Is one of the industrial automation process control pipe pressure components, usually used for pipeline medium, remote control (connected, to cut off the medium).Electric ball valve standard GB/T21465-2008 "valve terms" are defined as opening and closing (sphere) driven by the valve stem, and around the axis of rotation movement of the valve stem.Mainly used for truncated or on line in the medium, can also be used for regulation and control of the fluid, including hard seal v-shaped ball valve the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, micro solid material such as medium.Electric ball valve can be divided into electric flanged ball valves, electric ball valves to the clamp, electric welding ball valves, electric threaded ball valve.According to seal form is divided into soft seal electric ball valve, hard seal electric ball valve.
