A ball float valve uses a buoyant float ball connected to a valve mechanism to automatically control liquid flow. As the liquid level rises, the float rises and closes the valve to shut off flow. When the level drops, the float descends and reopens the valve, maintaining a consistent liquid level in tanks and chambers.
