Float valves are used in toilets to regulate the flow of water into the bowl. The float is connected to a lever that controls a ball valve. When the water level in the bowl drops, the float lowers and opens the ball valve to allow water to enter the bowl. When the water level in the bowl rises, the float rises and closes the ball valve to prevent water from entering the bowl.
Lever ball valves are used in toilets to turn off and on the flow of water. The lever is connected to a ball valve that controls the flow of water. When the lever is in the up position, the ball valve is open and water flows into the bowl. When the lever is in the down position, the ball valve is closed and water does not flow into the bowl.
