Compared with other kinds of valve pneumatic ball valve

Pneumatic ball valve structure is compact, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, and is suitable for water, solvents, acids and generally working medium, such as natural gas is mainly used for cutting or on line in the medium, can also be used to adjust and control of the fluid. Compared with other type valve, pneumatic ball valve has a quarter-turn output torque, start quickly, stable and reliable, applicable widely, and the following several advantages. Anti-static function: in a sphere, the valve stem and valve body between spring, will be generated switching process of electrostatic export. AT flameproof pneumatic high platform for flange ball valve pneumatic four points AT silk mouth ball valve pneumatic stainless steel flanged ball valves AT long service life: because the materials such as ptfe has good self-lubrication, with ball friction loss is small, so the pneumatic ball valve. Fluid resistance small, pneumatic ball valves are classified all valves fluid resistance in the smallest one, even the pneumatic ball valve, reducing the fluid resistance is small. Stem seal reliable: it has two seal face, and widely used all kinds of plastic ball valve sealing surface of materials, good sealing, can realize completely sealed. Have been widely used in the vacuum system. Due to the valve stem will only be used as the rotation without lifting movement, the valve stem packing seal is not easy to damage, and sealing ability increases as the medium pressure increases. Seat sealing performance is good: using ptfe sealing ring made of elastic material, such as the structure is easy to be sealed, and pneumatic ball valve valve sealing ability increases as the medium pressure increases. Thrust bearings reduce stem friction torque, can make the valve stem long smooth and flexible operation. Simple structure, small volume, light weight. Easy to operate, open and close quickly: from open to close just rotate 90 °, is advantageous for the remote control. Easy maintenance: ball valve has simple structure, sealing ring, which generally remove replacement is more convenient. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. Applicable range: size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Because the ball valve have to wipe in the process of opening and closing, so can be used to bring in the medium of suspended solid particles. High machining precision: expensive, unfavorable use in high temperature, such as pipe contains impurities, easily blocked by impurities, lead to valve cannot open.
