[0002] A ball valve is a valve whose opening and closing ball is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into: pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.

[0003] Bonnet: The bonnet is a part of the ball valve body that is used to seal the medium inside the valve. It is usually made of cast or forged metal for strength and corrosion resistance.
