Ball valve, which is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. There is a strong shear force between the V-shaped ball core of the hard-sealed V-shaped ball valve and the metal valve seat of hard-welded carbide. It is especially suitable for the medium containing fiber and small solid particles. On the pipeline, the multi-pass ball valve can not only flexibly control the confluence, diversion and flow direction of the medium, but also close any channel to connect the other two channels. This type of valve shall generally be installed horizontally in the pipeline. The ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve according to the driving mode.

Since rubber, nylon and polytetrafluoroethylene are usually used as the seat sealing ring materials for ball valves, its service temperature is limited by the seat sealing ring materials. The cut-off function of ball valve is achieved by pressing the metal ball against the plastic valve seat under the action of medium (floating ball valve). Under the action of certain contact pressure, the valve seat sealing ring undergoes elastic-plastic deformation in local areas. This deformation can compensate the manufacturing accuracy and surface roughness of the ball and ensure the sealing performance of the ball valve.

Because the valve seat sealing ring of ball valve is usually made of plastic, the fire resistance and fire prevention of ball valve should be considered when selecting the structure and performance of ball valve, especially in petroleum, chemical, metallurgical and other departments, and in equipment and pipeline systems with flammable and explosive media, fire resistance and fire prevention should be paid more attention. Generally, ball valves are recommended for pipeline systems with two-position adjustment, strict sealing performance, mud, wear, necking channel, rapid opening and closing action (1/4 turn opening and closing), high pressure cut-off (high pressure difference), low noise, cavitation and gasification, small leakage to the atmosphere, small operating torque and small fluid resistance.

Ball valve is also applicable to the pipeline system with light structure, low pressure cut-off (low pressure difference) and corrosive medium. Ball valves can also be used in low-temperature (cryogenic) devices and pipeline systems. In the oxygen pipeline system of the metallurgical industry, ball valves with strict degreasing treatment need to be used. When the main pipeline in the oil and gas pipelines needs to be buried underground, the full-bore welded ball valve shall be used. When regulating performance is required, ball valve with special structure with V-shaped opening shall be selected. In petroleum, petrochemical, chemical, power and urban construction, metal-to-metal sealed ball valves can be selected for pipeline systems with operating temperature above 200 ℃.
