The ball valve came out in the 1950s, with the Ball valve

With the rapid development of science and technology, the continuous improvement of production technology and product structure, in just 40 years, it has rapidly developed into a major valve. In Western industrially developed countries, the use of ball valves is increasing year by year.

In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries, occupying a pivotal position in the national economy. It has the action of rotating 90 degrees, the cock body is a sphere, with a circular through hole or channel passing through its axis.

The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. It only needs to be operated with a 90-degree rotation and a small torque to close tightly. The ball valve is most suitable for on-off and shut-off valves, V-shaped ball valve. In addition to paying attention to pipeline parameters, electric valves should pay special attention to the environmental conditions of their use. Since the electric device in the electric valve is an electromechanical device, its use status is greatly affected by its use environment. Under normal conditions, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments.
