Pneumatic ball valve is composed of ball valve pneumatic actuator, pneumatic actuator is divided into double-acting pneumatic actuator and single-acting pneumatic actuator, controlled by the solenoid valve to achieve ball valve switching action. Pneumatic ball valve can be intelligent control, quickly open or close the pipeline, can effectively control and manage the pipe network. Ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small turning moment can be closed tight. Ball valves are best suited for switching and shut-off valves, but recent developments have designed ball valves to provide throttling and control flow, such as V-ball valves. Pneumatic ball valve application: Ball valve itself is compact, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often closed state, easy to be media erosion, easy to operate and repair, suitable for water, solvents, acids and natural gas, etc. Working medium, but also for poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, etc., are widely used in various industries. Ball valve body can be a whole, it can be combined. Pneumatic ball valve features: Pneumatic ball valve is mainly used to cut off or connect the media in the pipeline, can also be used for fluid regulation and control, pneumatic valve compared with other types of valves, with angular stroke output torque, open fast, stable and reliable , Wide range of applications, and so on the following advantages. 1, the fluid resistance is small, pneumatic valve is all the valves in the classification of a fluid resistance of the smallest, even reduced diameter pneumatic valve, the fluid resistance is quite small. 2, thrust bearing to reduce stem friction torque, valve stem long-term operation can be smooth and flexible. 3, the valve seat sealing performance, the use of PTFE and other elastomeric seals, the structure is easy to seal, and pneumatic valve sealing ability with the medium pressure increases. 4, the stem seal is reliable, because the stem only fake rotary motion without lifting movements, stem packing seal is not easy to damage, and the sealing capacity increases with the media pressure increases. 5, due to PTFE and other materials with good self-lubricating, and the ball friction loss is small, so the life of pneumatic ball valve long. 6, Bottom stem and valve stem convex steps to prevent the valve stem ejected, such as a fire caused by the stem seal damage, convex step and the body can also form a metal contact between the stem to ensure that the seal. 7, anti-static function: set the spring between the ball, stem, valve body, the static electricity generated by the switching process can be exported.
