Shanghai forged steel ball valve forged steel ball valve advantages 
 A. Fluid resistance is small, full bore ball valve basic flow resistance. 
 Two. Simple structure, small size and light weight. 
 3. Close and reliable. It has two sealing surface, and the valve sealing surface material widely used kinds of plastic, good sealing, can be completely sealed. Also been widely used in the vacuum system. 
 4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. 
 5 Easy maintenance, simple valve structure, the seals are generally activities, removal of the replacement is more convenient. 
 6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, through the media, does not cause erosion of the valve sealing surface. 
 7. Wide scope of application, the path from childhood to a few millimeters to a few meters from the high vacuum to high pressure can be applied. 
 8. The ball valve opening and closing process, wipe, so can be used for media with suspended solids.
