Pneumatic ball valves are widely used in chemical, petrochemical and other industries.
The pneumatic ball valve is a ball valve driven by a piston-type cylinder, with accessories such as solenoid valve, limit switch box, filter pressure relief valve, etc., to complete active control. Pneumatic ball valves are generally used for fast blocking. Its excellent sealing function and fast blocking speed cannot be replaced by other valves. It is also equipped with an electric valve positioner to make a pneumatic regulating ball valve to adjust the flow or pressure of the medium.
Pneumatic ball valve can be divided into single effect and double effect according to the form of cylinder. Double effect pneumatic ball valve switch requires air source, while single effect pneumatic ball valve needs air source when opening or closing. It will be automatically reset due to the effect of the spring. For those working conditions that require the valve to be automatically reset in some cases, it is necessary to choose a single-effect pneumatic ball valve.
Pneumatic ball valve body can be combined or integrated. Has the same rotation lifting action as a plug valve, but the difference is that the plug body is a sphere with a passage through its axis or a circular through hole. The proportion of the spherical surface and the channel mouth is that when the ball rotates 90 degrees, the spherical surface should be fully displayed at the entrance and exit, and then the movement will be blocked.
There are many types of pneumatic ball valves, including pneumatic flanged ball valves, pneumatic threaded ball valves, pneumatic ultra-thin ball valves, pneumatic O-shaped ball valves, pneumatic V-shaped ball valves, pneumatic three-way ball valves, pneumatic four-way ball valves, pneumatic sanitary ball valves, pneumatic vacuum ball valves, Pneumatic insulation ball valve, pneumatic fluorine-lined ball valve, etc. Pneumatic O-type ball valve is suitable for switching two-position blocking, pneumatic V-type ball valve is suitable for adjustment, and is generally used for active control of pulp and other media in the paper industry. Pneumatic three-way ball valve and four-way ball valve are used to reverse the medium. , while the pneumatic sanitary ball valve is suitable for food, pharmaceutical and other occasions with high hygiene requirements, the pneumatic fluorine-lined ball valve is suitable for corrosive media, and the pneumatic thermal insulation ball valve is suitable for simple crystallization or media that will solidify at room temperature, such as asphalt, etc. .
