Ball valve history
- Apr 28, 2018 -

The ball valve was born in the 1950s. With the rapid development of science and technology, continuous improvement of the production process and product structure, it has rapidly developed into a major valve in a short period of 40 years. In the developed countries of 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, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal, steel and other industries. The national economy plays a decisive role. It has an action of rotating 90 degrees, the plug body is a sphere, has a circular through hole or passage through its axis. The ball valve is mainly used in the pipeline to cut off, distribute and change the direction of flow of the medium. It only needs to rotate with 90 degrees of operation and a small rotating torque can close the tight. Ball valve is the most suitable switch, shut-off valve use, V-ball valve. In addition to paying attention to piping parameters, electric valves should pay special attention to the environmental conditions in which they are used. Because the electric device in an electric valve is an electromechanical device, its use status 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.
