A level control valve, also known as an altitude control valve, is a device that automatically adjusts to changes in the liquid level within a storage system. This type of valve responds to variations in liquid height to maintain a desired level, ensuring efficient and safe operation of fluid storage.
For instance, ballcocks in flush toilets are a common example of level control valves, as they activate based on the filling or emptying of the tank, managing each stage of the flush cycle to ensure proper function. Level control valves are essential in various applications, helping to regulate liquid levels in tanks, reservoirs, and other storage systems, thereby enhancing system reliability and preventing overflow or dry running conditions.
