Pneumatic ball valveFeatures: angular stroke output torque, quick opening, stable and reliable, and wide application.
Pneumatic ball valveIt is mainly used to cut off or connect the medium in the pipeline. It can also be used for fluid adjustment and control. Compared with other valves, it has the following advantages.
1. Small fluid resistance,Pneumatic ball valveIt is the least fluid resistance of all valves, even with reduced diameterPneumatic ball valve, Its fluid resistance is also quite small.
2. The thrust bearing reduces the friction moment of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
3. The valve seat has good sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene, the structure is easy to seal, andPneumatic ball valveThe sealing capacity of the valve increases with the increase of the medium pressure.
4. The valve stem is reliable in sealing. Since the valve stem is only used for imitating rotation and not for lifting movement, the packing seal of the valve stem is not easy to be damaged, and the sealing ability increases with the increase of the pressure of the medium.
5. Since materials such as polytetrafluoroethylene have good self-lubricating properties, the friction loss with the sphere is small, soPneumatic ball valveThe service life is long.
6. The bottom-mounted valve stem and the convex step of the valve stem head prevent the valve stem from spraying out. If the valve stem seal is damaged due to fire, the convex step and the valve body can also form metal contact to ensure the valve stem seal.
7. Anti-static function: A spring is set between the ball, valve stem and valve body, which can lead out the static electricity generated during the switching process.
