A ball valve is a type of valve where the closure element (the ball) is driven by the valve stem and rotates around the axis of the valve. It can also be used for regulating and controlling fluid flow. The hard-seated V-type ball valve, in particular, features strong shear force between the V-notch ball core and the metal seat with hard-faced alloy welding, making it especially suitable for media containing fibers or fine solid particles. Multi-port ball valves offer flexible control over the merging, diverting, and switching of flow directions in pipelines, while also allowing any channel to be closed to connect the other two. This type of valve should generally be installed horizontally in pipelines. Based on the actuation method, ball valves are categorized into: pneumatic ball valves, electric ball valves, and manual ball valves.
