Pneumatic O-type cut-off ball valves are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control. Compared with other valve types, they have the following advantages.

1. Pneumatic ball valves have the lowest fluid resistance among all valve types, even for reduced diameter ball valves, their fluid resistance is quite small.

2. Thrust bearings reduce the friction torque of the valve stem, allowing for long-term balanced and flexible operation of the valve stem.

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

4. The valve stem seal is reliable. As the valve stem only rotates without lifting, the packing seal of the valve stem is not easily damaged, and the sealing ability increases with the increase of medium pressure.

5. Due to the good self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, resulting in a long service life of the ball valve.

6. The bottom mounted valve stem and valve stem head protrusion prevent the valve stem from spraying out. In the event of a fire causing damage to the valve stem seal, metal contact can also be formed between the protrusion and the valve body to ensure valve stem sealing.

7. Anti static function: Install springs between the ball, valve stem, and valve body to dissipate static electricity generated during the switching process.
