High and medium pressure pneumatic ball valves are composed of three-piece ball valves and pneumatic actuators. The pneumatic actuators are divided into double-acting and single-acting types. The ball valve is controlled by a solenoid valve to realize the switching action. High and medium pressure pneumatic ball valves can realize intelligent control, quickly open or close the pipeline, and can effectively control and manage the pipeline network.

Features of Lined Ball Valve: angular stroke output torque, rapid opening, stable and reliable, and widely applicable.

High and medium pressure pneumatic ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Compared with other valve types, it has the following advantages.

1. Small fluid resistance. High and medium pressure pneumatic ball valves are the type with the smallest fluid resistance among all valve types. Even the reduced diameter high and medium pressure pneumatic ball valves have a very small fluid resistance.

2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.

3. The valve seat has good sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene is used. The structure is easy to seal, and the valve sealing capacity of the high and medium pressure pneumatic ball valve increases with the increase of medium pressure.

4. The valve stem seal is reliable. Since the valve stem only moves in rotation but not in lifting and lowering motion, the packing seal of the valve stem is not easy to be damaged, and the sealing capacity increases with the increase of medium pressure.

5. Since materials such as polytetrafluoroethylene have good self-lubrication and small friction loss with the ball, the service life of the high and medium pressure pneumatic ball valve is long.

6. The bottom-mounted valve stem and the convex step of the valve stem head prevent the valve stem from spraying out. If the valve stem seal is damaged due to fire, the convex step can also form metal contact with the valve body to ensure the sealing of the valve stem.

7. Anti-static function: A spring is set between the ball, the valve stem, and the valve body to conduct the static electricity generated during the switching process.
