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.

|
Split body design with flanged ends for fast installation, in-line maintenance and rebuilding |
Solid ball construction provides structural integrity and minimizes flow turbulence |
|
Mounting pad complied with ISO 5211 for ease and interchangeability of actuation |
Bottom-loaded blow-out proof stem |
|
Investment cast body & cap on sizes 1/2"to 4" Sand cast body & cap on sizes 5" to 10" |
Body joint is designed to prevent excessive compression of valve internals, resulting in a consistent and low operating torque |
