The Origin Of Lined Ball Valve

Lined Ball Valve was invented in the 1950s. With the rapid advancement of science and technology, and continuous improvements in production processes and product structure, it has rapidly developed into a major valve type in just 40 years. In industrialized Western countries, the use of ball valves is increasing year by year.
In my country, ball valves are widely used in industries such as oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, power generation, municipal engineering, and steel, playing a vital role in the national economy. They feature a 90-degree rotating body, a spherical rotor, and a circular hole or channel passing through its axis.
In pipelines, ball valves are primarily used to shut off, distribute, and change the flow direction of media. They require only a 90-degree rotation and minimal torque to achieve a tight closing. Ball valves are most suitable for on-off and shut-off valves, such as V-shaped ball valves. In addition to pipeline parameters, electric valves should also pay special attention to the environmental conditions in which they are used. Because the electric actuator in an electric valve is an electromechanical device, its performance is significantly affected by the operating environment. Under normal circumstances, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments.
