Features of Flanged Pneumatic Ball Valve

Small fluid resistance and wide ball width are the smallest fluid resistance among all ball types. Even if the ball width is reduced, its fluid resistance is quite small.

The thrust bearing reduces the friction moment of the wide pole, making the long-term operation of the broad pole stable and flexible.

Anti-static function: A spring is set between the sphere, the wide rod and the wide body, which can discharge the static electricity generated during the switching process.

Since materials such as polytetrafluoroethylene have good self-lubricating properties and have small friction losses with the ball, the ball valve has a long service life.

The bottom-mounted valve stem and the convex steps on the valve stem head prevent the valve stem from spraying out. If the wide stem seal is damaged due to fire, metal contact can also be formed between the convex steps and the valve body to ensure the wide stem seal.

The valve stem seal is reliable. Since the wide stem only performs imitating rotation and not lifting movement, the packing seal of the valve stem is not easily damaged, and the sealing capacity increases as the pressure of the medium increases.

The valve seat has good sealing performance. It uses a sealing ring made of elastic materials such as polytetraoxide. The structure is easy to seal, and the valve sealing capacity of the ball width increases with the increase of the medium pressure.
