What is the role of isolation valves in a distribution system?

Isolation valves play a crucial role in a distribution system by allowing specific sections of the pipeline to be shut off for maintenance or repairs without disrupting the entire system. This function is essential for the ongoing management and upkeep of water distribution networks. When a section of the pipeline requires inspection, repair, or routine maintenance, closing the isolation valve prevents water from flowing into that section, thereby enabling work to be conducted safely and efficiently. By isolating parts of the system, operators can minimize service interruptions for customers and maintain the overall integrity of the water supply.
