Floating Ball Valve

Categories:Floating Ball Valve

Brief Introduction


FYV’s 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.
