The advantages of pneumatic ball valve

Compared with the other valves, pneumatic ball valve has the following advantages:


1. Fluid resistance is small, its resistance coefficient with section of equal length.
2。 Simple structure, small volume, light weight, long service life.
3。 Anti-static function: in a sphere, the valve stem and valve body between spring, will be generated switching process of electrostatic export.
4。 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.


5. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.


6. Bottoms type valve stem and valve stem head convex order to prevent the valve stem, convex order between the body and also can form metal contact, to ensure that the valve stem seal.
7。 Convenient maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient.
