Ball valve history
- Sep 12, 2018 -

The ball valve was introduced in the 1950s.With the rapid development of science and technology, continuous improvement of production technology and product structure, it has rapidly developed into a major valve category in just 40 years. In countries with developed industries in the West, the use of ball valves is increasing year by year.

In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, occupying a pivotal position in the national economy. It has a 90 degree rotation action, the cock body is a sphere, with a circular through hole or passage through its axis.

The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be rotated 90 degrees and the torque can be closed tightly. The ball valve is most suitable for use as a switch and shut-off valve, V-type ball valve. In addition to paying attention to the pipeline parameters, electric valves should pay special attention to the environmental conditions used. 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, electric ball valves and butterfly valves should be used with special care in the following environments.
