China Chaofan Long Service Life Pneumatic O Type Ball Valve

Main features
•Fluid resistance small, ball valve is the smallest one among all types valves, even reducing ball valve, its fluid resistance is quite small.
•Thrust bearings reduce stem friction torque, can make the valve stem long smooth and flexible operation.
•Seat sealing performance is good, use the sealing ring made of elastic material, such as PTFE, structure is easy to seal, and valve seat sealing ability increases as the medium pressure increases.
•Stem sealing is reliable, because stem only have rotation movement and no lifting movement, the valve stem packing seal is not easy to damage, and sealing ability increases as the medium pressure increases.
•PTFE has good self-lubrication, its friction force with sphere is small, so the ball valve is of long service life.
•Bottoms, the valve stem and valve stem head convex order to prevent the valve stem, stem seal damage caused by such as fire, convex order between the body and can also form a metal contact, to ensure that the valve stem seal.
•Anti-static function: in a sphere, the valve stem and valve body between spring, static export will be generated switching process.
