True or False: Isolating valves are used to cut off sections of a system.

Isolating valves are specifically designed to control the flow of water within a system by cutting off sections when needed. This feature allows operators to manage specific parts of a water distribution system without needing to shut down the entire system, which can be crucial for both routine maintenance and unforeseen repairs.

By isolating sections of a pipeline or water system, these valves help ensure that services can continue in other areas, making them a vital component in maintaining efficiency and service reliability. Their function goes beyond just emergencies or maintenance, as they can also be used during operational adjustments, system upgrades, or routine inspections. Therefore, the statement that isolating valves are used to cut off sections of a system is accurate and aligns with practical applications in water management.
