The advantages of insulation ball valve door

Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Close and reliable, and the widespread use of plastic ball valve sealing surface of the door materials, sealing is good, have been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate it 90 & deg; To facilitate remote control. Convenient maintenance, simple ball valve door 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. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
