Principle of the cast steel floating ball valve: This kind of floating ball valve has a ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.
The floating ball valve is mainly divided into such two structures as the single-body type and double-body type.
Valve Features
| Split body design with flanged ends for fast installation, in-line maintenance and rebuilding | Solid ball construction provides structural integrity and minimizes flow turbulence |
