Butt weld ball valve closure member is a sphere, it is relying on the sphere around the centerline of the valve body 90-degree rotation to achieve open and close a valve. The straight-through ball valve is mainly used to cut off the medium in the pipeline. There is a two-piece and three-piece structure. Butt welding methods include socket welding, groove welding, and flat welding. The butt-welded ball valve is a new type of valve that has been widely used in recent years. These valves can be installed horizontally or vertically.
