Characteristics of Pneumatic Floating Ball Valve

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

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, and the sealing ring is made of elastic materials such as polytetrafluoroethylene. The structure is easy to seal, and the sealing ability of the 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 the protruding step at the head of the valve stem prevent the valve stem from spraying out. In the event of a fire causing damage to the valve stem seal, the protruding step can also form a metal contact with the valve body to ensure the valve stem seal.

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

Pneumatic floating ball valve

This ball valve is 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, it has the following advantages.
