Pneumatic ball valve is mainly used to cut off or connect the media in the pipeline, can also be used for fluid regulation and control, its advantages compared with other valves: 1, the fluid resistance is small, the valve is all valves in the fluid resistance minimum A, even reducing the ball valve, the fluid resistance is quite small. 2, thrust bearing to reduce stem friction torque, valve stem long-term operation can be smooth and flexible. 3, the valve seat sealing performance is good, the seal ring made of elastic material such as PTFE, the structure is easy to seal, and the valve sealing ability of the ball valve increases with the increase of medium pressure. 4, the stem seal is reliable, because the stem only fake rotary motion without lifting movements, stem packing seal is not easy to damage, and the sealing capacity increases with the media pressure increases. 5, due to PTFE and other materials with good self-lubricating, and friction loss of the ball is small, so the long service life of the ball valve. 6, Bottom stem and valve stem convex steps to prevent the valve stem ejected, such as a fire caused by the stem seal damage, convex step and the body can also form a metal contact between the stem to ensure that the seal. 7, anti-static function: set the spring between the ball, stem, body, the static electricity generated by the switching process can be exported to the implementing agencies.
