Pneumatic ball valve is mainly used to cut off or connect the medium in the pipeline. It can also be used for the regulation and control of fluids. It has advantages compared to other valves:
1. The fluid resistance is small, and the ball valve is the one with the smallest fluid resistance in all valves. Even if it is a reduced diameter ball valve, the fluid resistance is also very small.
2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate steadily and flexibly for a long time.
3, the valve seat sealing performance is good, using PTFE and other elastic materials made of seals, the structure is easy to seal, and the ball valve sealing ability increases with the increase of medium pressure.
4. The valve stem seal is reliable, because the valve stem is only used for imitating rotation without lifting movement, the filling seal of the valve stem is not easy to damage, and the sealing capacity increases as the pressure of the medium increases.
5, due to PTFE and other materials have good self-lubricating properties, and the ball friction loss is small, so the ball valve has a long service life.
6. The convex stem of the bottom-mounted stem and the stem head prevents the valve stem from being sprayed. If the fire causes the stem seal to fail, a metallic contact can also be formed between the convex step and the valve body to ensure the stem seal.
7, anti-static function: set the ball between the ball, valve stem, valve body, static electricity can be derived from the switching process, the executive body.
