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, it has rapidly developed into a major valve type in just 40 years. In developed western 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 occupy a pivotal position in the national economy. It has the action of rotating 90 degrees, and 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 be rotated 90 degrees and a small torque can be closed tightly. The ball valve is most suitable for use as a switch and cut-off valve, and a V-shaped ball valve. Electric valve removal

In addition to paying attention to the parameters of the pipeline, special attention should be paid to the environmental conditions of its use. Since the electric device in the electric valve is an electromechanical device, its use state 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.
