A ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, paper-making, pharmaceutical, water conservancy, electric power, steel and other industries, and plays an important role in economy. 

The ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium. It only needs to rotate 90 degrees with small torque to close tightly. It is opened when the hole of the ball is in line with the flow and closed when it is pivoted 90-degrees.
