Float valves automatically control liquid levels in tanks and reservoirs. They operate based on the movement of a float that rises and falls with the liquid level. When the desired level is reached, the valve shuts off the flow. Commonly used in overhead tanks, storage tanks, and industrial reservoirs. Float valves prevent overflow and water wastage. They ensure consistent liquid levels without manual intervention. Simple mechanical operation ensures reliability. These valves are cost-effective and easy to install. Suitable for water and non-corrosive liquids. Widely used in residential, commercial, and industrial applications.
