How wide is the application range of ball valves

Ball valves are widely used in the industrial field, mainly in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel, and other industries. In Western industrially developed countries, ball valves use is increasing yearly. Ball valves are mainly used to cut off, distribute, and change the flow direction of the medium in the pipeline. They only need to be rotated 90 degrees to close tightly, which is very suitable for use as switch and cut-off valves.
