A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve's axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their V-shaped ball core and hard alloy-faced metal seat, possess strong shearing force, making them particularly suitable for media containing fibers or small solid particles.
Multi-port ball valves in pipelines can flexibly control the merging, splitting, and switching of flow directions of media, and can also close any channel while connecting two other channels. These valves should generally be installed horizontally in pipelines. Ball valves are classified according to their actuation method: pneumatic ball valves, electric ball valves, and manual ball valves.
