Pneumatic ball valve and other valve types, with the angle of the output torque, open quickly, stable and reliable, and the application of a wide range of advantages, such as the following.
1, thrust bearings to reduce the friction torque of the valve stem, so that the valve stem is stable and flexible long-term operation.
2, anti-static function: in the sphere, the valve stem, the valve between the spring, can be generated by the switching process of static electricity.
3, due to PTFE and other materials with good self lubrication, with the ball of the friction loss of small, so pneumatic ball valve with long service life.
4, the fluid resistance is small: pneumatic ball valve is the valve classification of fluid resistance in the smallest one, even if it is the size of the pneumatic ball valve, the fluid resistance is also very small.
5, valve stem seal reliable: because stem only for imitation rotation transported without doing the lifting movement, stem packing seal is not easy to destroy, and the sealing ability increased with the increase of the pressure of the medium.
6, the valve seat sealing performance is good: the use of PTFE and other elastic material made of sealing ring, the structure is easy to seal, and the valve sealing ability of the valve with the increase of the media pressure.
