1, the fluid resistance is small, its resistance coefficient with section of equal length.
2, simple structure, small volume, light weight.
3, compact and reliable, ball valve sealing surface material widely used plastic, sealing is good, have been widely used in the vacuum system.
4, easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.
5, convenient maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient.
6, in the 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.
7, pneumatic ball valve manufacturer applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
8, because the power supply adopts pneumatic ball valve is gas, general is 0.
8 mpa pressure, is relatively safe.
If air leakage, pneumatic ball valve relative hydraulic, electric, gas can directly discharge, no pollution to the environment, and has higher security.
9, relative to manual and turbine rotating ball valves, pneumatic ball valve can be large caliber configuration, (
Manual and turbine rotating ball valve is generally under 12 caliber, pneumatic ball valve to 48 ') diameter.
Pneumatic ball valve manufacturer has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
