Standard: GBT12238The fluid resistance is small, and the ball valve is the one with the smallest fluid resistance among all valves. Even if it is a reduced diameter ball valve, its fluid resistance is quite small.
The thrust bearing reduces the frictional moment of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
The sealing performance of the valve seat is good, and the sealing ring made of ammunition materials such as polytetrafluoroethylene is adopted, and the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.
4. The sealing of the valve stem is reliable. Since the valve stem only performs imitation rotation and does not perform lifting movement, the packing seal of the valve stem is not easy to be damaged, and the sealing ability increases with the pressure of the medium.
5. Due to the good self-lubricating properties of polytetrafluoroethylene and other materials, the friction loss with the ball is small, so the service life of the ball valve is long.
6. Bottom-mounted valve stem and the convex step on the head of the valve stem prevent the valve stem from blowing out. If the valve stem seal is damaged due to fire, metal contact can also be formed between the convex step and 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, which can discharge the static electricity generated during the switching process
