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 Cast Floating ball design supports the ball with two PTFE seats, one on the upstream and the other on the downstream side of the ball. The upstream pressure pushes the ball which compresses the downstream side seat to completely shut off fluid control.

Cast Floating ball design supports the ball with two PTFE seats, one on the upstream and the other on the downstream side of the ball. The upstream pressure pushes the ball which compresses the downstream side seat to completely shut off fluid control. All Casted Floating Ball Valves are with reliable high quality castings and fire safe design certified according to BS 6755, API607 & API 6FA. Meet all applicable ASME standards.
