Ball valve ball is floating, under the effect of medium pressure, the fitness ball produce certain displacement and compression at the outlet seal surface, guarantee the outlet seal.

Floating ball ball valve has simple structure, good sealing, but all spheres of work under medium load to export sealing ring, so want to consider to seal material can withstand the working load of sphere medium, under high pressure shock, sphere migration may occur. In this structure, is generally used in low pressure ball valve.

Ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields. Ball valve body can be a whole, also can be combined.
