Floating Ball Valve
Floating Ball Valve

A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body; it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure a reliable seal. The floating ball valve is a simple design with good sealing performance relying on the seat material to withstand the workload as the sealing pressure is barred by the seat ring. Floating ball valves are mainly used in low to mid level pressure applications. FBV manufactures the floating ball valve class 150 to class 600.

The blow out proof design for the stem assures that even if the pressure in the body cavity has risen accidentally and the packing flange breaks, the stem cannot be blown out by the medium. The stem features a backseat, assembled from within the body. The sealing force against the backseat gets higher as the medium pressure becomes higher. Therefore, a reliable stem seal can be assured under variable medium pressures. The stem cannot be removed during service.
