Ball valve came out in the 1950s. With the rapid development of science and technology and the continuous improvement of production process and product structure, it has rapidly developed into a main valve in just 40 years. In western industrial developed countries, the use of ball valves is increasing year by year.

In China, ball valves are widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel and other industries, and play an important role in the national economy. The cock body is a sphere, and a circular through hole or channel passes through its axis.

The ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. It can be closed tightly only by rotating 90 degrees and a small rotating torque. Ball valve is most suitable to be used as switch and shut-off valve, V-shaped ball valve. In addition to the pipeline parameters, special attention shall be paid to the environmental conditions for the use of electric valves. Since the electric device in electric valves is an electromechanical equipment, its service state is greatly affected by its service environment. Under normal conditions, special attention shall be paid to the use of electric ball valve and butterfly valve in the following environments.
