Ball valve castings are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control. Among them, the hard sealed V-shaped ball valve has a strong shear force between its V-shaped core and the metal valve seat welded with hard alloy, which is particularly suitable for media containing fibers, small solid particles, etc. Ball valve castings are generally divided into handle cast steel ball valves, pneumatic cast steel ball valves, electric cast steel ball valves, cast iron ball valves, stainless steel ball valves, all copper ball valves, etc.
