Floating Ball Valve
1. Description of Floating Ball Valve:
The floating ball valve is a valve with its ball floating inside the valv body; it drifts to the downstream side
and will be tightly pushed against the seat by the medium pressure to ensure a reliable seal. The floating
ball valve is a simple design with good sealing performance and relying on the seat material to wthstand
the workload since the sealing stress is mainly imposed on the seat rings. Hence floating ball valves are
usually used in low and medium pressure ratings.
