Ball Valves Features:
1. Small fluid resistance, ball valve is one of the smallest fluid resistance in all kinds of valves, even if it is a reducing ball valve, its fluid resistance is also quite small.
2. The thrust bearing reduces the friction torque of the valve rod, which can make the long-term operation of the valve rod stable and flexible.
3. The sealing performance of the valve seat is good. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure.
4. The valve rod seal is reliable. Because the valve rod only rotates as if without lifting movement, the packing seal of the valve rod is not easy to be damaged, and the sealing capacity increases with the increase of the medium pressure.
5. As PTFE and other materials have good self-lubricating property and small friction loss with the ball, the service life of the ball valve is long.
6. The bottom mounted valve rod and the convex step at the head of the valve rod can prevent the valve rod from ejecting. If the fire causes damage to the valve rod seal, metal contact can also be formed between the convex step and the valve body to ensure the valve rod seal.
7. Anti static function: a spring is set between the ball, the valve rod and the valve body, which can lead out the static electricity generated in the switching process.
