What is a floating type ball valve?

The floating ball valve is a kind of valve that its ball floating inside the valve body; it drifts to the downstream side and would be tightly pushed against the seat by the medium pressure, to ensure a reliable seal. It is a quite simple design with a good sealing performance and relying on the seat material to bear the workload since the sealing stress is mainly imposed on the seat rings. Usually the floating ball valves are working in the pipeline system with a low and medium pressure ratings.
