Abstract
A flush valve is provided for discharging fluid from a tank. The flush valve includes a flapper. The flapper includes a frame portion and a hollow float portion rotatably connected to the frame portion. A relative rotational position between the frame portion and the float portion adjusts at least one opening formed between the frame portion and the float portion, and controls an amount of fluid discharged from the tank by variably adjusting buoyancy of the flapper.
