Product Name:
Ball Valve Steel Casting, Cast Steel Globe Valve in Chinese
Foundry, Ball Check Metal Casting Company
The advantages and disadvantages of ball valve:
1. The lowest flow resistance (virtually zero).
2. It can not be stuck at work without the lubricant and then be
reliably applied to the corrosive medium and low boiling point
liquid.
3. In a larger range of pressure and temperature, it can be
completely sealed.
4. A quick open-shut part. Gate valve quickly, the operation of
non-impact.
5. Ball closing members can achieve automatic position on the
border locations.
6. The work of the media in the two-sided is reliable seal.
7. In the wide-open and full closed, when the ball and seat
sealing surface and the dielectric isolation, high-speed through
the valve, therefore the media will not cause erosion of the
sealing surface.
8. Light weight, compact conformation.
9. Body symmetry, in particular welded body structure, is under
the stress from the pipe commendably.
10. The closure of parts can support high pressure at the time
of the closure.
