What is the primary function of an altitude valve?

The primary function of an altitude valve is to control the water elevation in an elevated storage tank. Altitude valves are specifically designed to maintain a predetermined water level within a tank. When the water level reaches a certain height, the valve closes to prevent overflow, and when the level drops below a set point, it opens to allow more water to enter. This ensures that the tank remains at optimal levels for storage and supply, helping to manage the water distribution system efficiently.

In contrast, regulating flow rate in pipes, measuring pressure in the system, and filtering impurities are functions performed by different types of devices. Flow control valves are used for managing the rate of flow, pressure gauges or transmitters measure pressure levels, and filters are utilized to remove contaminants from water. Each of these functions is distinct and does not overlap with the primary role of an altitude valve, which is focused on maintaining water levels in storage tanks.
