The main components of the Ball Valve.

Ball valve was born in the 1950s, with the rapid development of science and technology, the continuous improvement of production process and product structure, in a short time of 40 years, has rapidly developed into a major valve class. In Western industrially developed countries, the use of ball valves is rising year by year.

In China, ball valves are widely used in petroleum refining, long-distance pipeline, chemical industry, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, playing a pivotal role in the national economy. It has the action of rotating 90 degrees, the cock body is a sphere, and there is a circular through hole or channel through its axis.

Ball valve in the pipeline is mainly used to cut off, distribute and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and a small torque to close tight. Ball valve is most suitable for switch, cut off valve use, V-shaped ball valve. In addition to the pipe parameters, the electric valve should pay special attention to the environmental conditions of its use, because the electric device in the electric valve is a mechanical and electrical equipment, its use status is greatly affected by its use environment. Under normal conditions, electric ball valves and butterfly valves should be used with special attention in the following environments.
