Pneumatic Actuator Ball Valve is composed of ball valve equipped with pneumatic actuator. The pneumatic actuator is divided into double-acting pneumatic actuator and single-acting pneumatic actuator. Pneumatic Ball Valve can realize intelligent control, quickly open or close the pipeline, can effectively control and manage the pipeline network.
Ball Valve in the pipeline is mainly used to do cut, distribution and change the direction of the flow of media, it only needs to rotate 90 degrees of operation and a small torque can be closed tightly. Ball valves are most suitable for use as switch and cut-off valves, but recent developments have designed them for throttling and flow control, such as v-type ball valves.
Application Of Pneumatic Actuated Ball Valve:
The ball valve itself has compact structure, reliable sealing, simple structure and convenient maintenance, the sealing surface and the ball surface are often in the closed state, not easy to be eroded by the medium, easy to operate and maintain, suitable for water, solvent, acid and natural gas and other general working media And also suitable for the working conditions of poor media, such as oxygen, hydrogen peroxide, methane and ethylene, in various industries have been widely used, such as drainage systems, exhaust systems, and so on. The ball valve body may be integral or modular.
Features Of Pneumatic Actuated Ball Valve:
The pneumatic ball valve is mainly used for cutting off or connecting the medium in the pipeline, and also can be used for regulating and controlling the fluid. Compared with other kinds of valves, the pneumatic ball valve has angular stroke output Torque, quick opening, stable and reliable, and is widely used And it has the following 7 advantages.
1. The fluid resistance is small, pneumatic ball valve is all kinds of valves in the smallest one, even reducing pneumatic ball valve, its fluid resistance is also quite small.
2. The thrust bearing reduces the friction Torque of the valve stem, can make the valve stem long-term smooth and flexible operation.
3. Seat sealing performance is good, the use of polytetrafluoroethylene and other elastic materials made of sealing ring, structure is easy to seal, and pneumatic ball valve sealing ability with the increase of medium pressure and increase.
4. Stem sealing reliable, as the stem only for rotating movement without lifting movement, the stem packing seal is not easy to destroy, and sealing capacity increases with the medium pressure.
5. Due to the Good self-lubrication of polytetrafluoroethylene and other materials, the friction loss with the ball is small, so the service life of pneumatic ball valve is long.
6. Lower-mounted stem and stem head convex steps to prevent stem spray, such as fire caused stem seal damage, convex steps and valve body can also form metal contact, ensure stem seal.
7. Anti-static function: a spring is arranged between the ball, valve stem and valve body to transfer the static electricity generated in the switching process.
