Advantages
1. The fluid resistance is small, it is the ball valve with the smallest fluid resistance among all valves. Even a ball valve with a reduced diameter has a relatively small fluid resistance.
2. Thrust bearing reduces the friction torque of the valve stem, which can make the valve stem work smoothly and flexibly for a long time.
3. Pneumatic ball valve seat has good sealing performance. The sealing ring made of elastic material such as polytetrafluoroethylene is easy to seal, and as the pressure of the medium increases, the valve sealing ability of the ball valve also increases.
4. The sealing of the pneumatic ball valve stem is reliable. Since the valve stem only imitates rotation without lifting movement, the packing seal of the valve stem is not easy to break, and as the pressure of the medium increases, the sealing ability also increases.
5. Due to the good self-lubricating properties of PTFE and other materials, the friction loss with the ball is small, so the service life of the ball valve is long.
6. The valve stem and the raised step of the valve stem head installed at the bottom can prevent the valve stem from popping out. If the valve stem seal is damaged by fire, metal contact may also be formed between the boss and the valve body to ensure the valve stem is sealed.
7. Anti-static function of pneumatic ball valve: a spring is installed between the ball, the stem and the valve body, the spring can output the static electricity generated by the switching process and the actuator.
