Japanese Standard ball valve

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

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

Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. They can be closed tightly with only 90 degrees of rotation and a small moment of rotation. Ball valves are most suitable for use as switch and cut-off valves, V-type ball valves. In addition to the pipe parameters, electric valves should pay special attention to the environmental conditions of their use. As the electric device in electric valves is an electromechanical equipment, 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.
