Ball valve basic information

The ball valve came out in the 1950s. 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 type. In Western industrially developed countries, the use of ball valves is increasing year by year.

In my country, 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, and play a decisive role 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 to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly. Ball valves are most suitable for use as switches and shut-off valves, V-shaped ball valves. In addition to paying attention to pipeline parameters, electric valves should also pay special attention to the environmental conditions in which they are used. Since the electric device in the electric valve is an electromechanical device, its usage status is greatly affected by its usage environment. Under normal circumstances, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments.
