Ball valves are mainly used to cut off or turn on the line of medium, can also be used to regulate and control the fluid, which has a strong hard seal between the valve V-ball core with its V-shaped carbide hardfacing metal seat shear force, especially for fiber-containing tiny solid particles and other media materials. The multi-way valve in the pipe can not only control the confluence flexible medium, diversion, and flow switch, but also to close any channel leaving the other two channels are connected. This type valve in the pipe should generally be installed horizontally. Electric valve actuators and ball by constitute electric ball. A pipeline pressure components in industrial automation process control, typically used for remote media channels on and off (turn on, off medium) control. Electric valve standard GB / T21465-2008 "valve term" is defined as: opening and closing parts (ball) driven by the stem valve, and around the valve stem axis of rotational movement. Mainly used for cut off or connected line of medium cast iron ball, can be used for fluid regulation and control valve priced, including a V-ball between hard sealing ball core with its V-shaped carbide hardfacing metal seat strong shear force, especially for fiber-containing tiny particles of solid material and other media. Flanged ball valve into electric power, electric wafer ball valve manufacturers, electric welded ball valve, electric threaded ball. The seal in the form of electric valve seal is also divided into soft, hard seal electric ball.
