The ball valve body may be integral or combined. The main features of the high-pressure ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often closed, which is not easily eroded by the medium, and is easy to operate and maintain. High-pressure ball valves are suitable for general working media such as water, solvents, acids and natural gas, and are also suitable for mediums with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, which are widely used in various industries.
