Ball valves: Cast Steel Floating Ball Valve


Principle of the cast steel floating ball valve: This kind of ball valve has a floating 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 float ball valve structures
