Introduction of ball valve

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

In China, ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and plays an important role 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.

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 torque to close tightly. Ball valve is most suitable for switch and cut-off valve, V-type ball valve. In addition to paying attention to pipeline parameters, electric valve should also pay special attention to the environmental conditions of its use. As the electric device in electric valve is an electromechanical equipment, its use status is greatly affected by its use environment. Usually, electric ball valve, butterfly valve in the following environment to pay special attention to the use.
