the hole in the ball is the same size as the pipeline resulting in lower friction loss.
The Cast Steel Ball Valve advantages:
1. Fluid resistance is small, the drag
coefficient is equal to the same length of pipe
sections.
2. Simple structure, small size, light weight.
3. Reliable and close the valve sealing surface
material widely used plastic, sealing, and has
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 structure, ball
valves, seals are generally active, demolition
replacement is more convenient.
6. When fully open or fully closed, the ball and
seat sealing surface and the dielectric
isolation, through the media, does not cause
erosion of the sealing surface of the valve.
7. A wide range of application, the path from
childhood to a few millimeters to a few meters,
from high vacuum to high pressure can be
applied.
