Three piece flange ball valves and gate valves belong to the same type of valve, with the difference being that their closing element is a spherical body that rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. Three piece ball valve is a new type of valve widely used in recent years.
