What is the purpose of water isolation valves?

The purpose of water isolation valves is primarily to control the flow of water in emergencies. These valves are designed to shut off the water supply in a specific section of a pipeline, allowing for maintenance, repairs, or during situations where there may be a leak or other issues that require immediate attention. By isolating certain sections of the water system, it helps prevent potential flooding, enables repairs without disrupting the entire water supply, and ensures safety for both workers and the public.

In contrast, increasing water pressure is achieved through different means, such as pumps, rather than using isolation valves. Treating water with chemicals falls under water treatment processes and does not pertain to the function of isolation valves. Reducing sediment in pipes relates to maintenance practices rather than the operational purpose of isolation valves. Therefore, the focus of isolation valves is significantly aligned with controlling water flow during critical situations to effectively manage the water supply system.
