What is the main purpose of valves in a water distribution system?

The main purpose of valves in a water distribution system is to control the flow of water. This is a crucial function because valves can be used to start, stop, or regulate the movement of water through pipelines. By opening or closing valves, operators can manage how much water is directed to different parts of the system, ensuring that the necessary supply reaches consumers while also maintaining system efficiency.

Controlling the flow is essential for various operational needs, such as isolating sections of the system for maintenance, responding to changes in demand, or managing pressure within the pipes. The ability to precisely control water flow helps to prevent issues such as water theft, leaks, or excess pressure that could damage infrastructure.

While pressure control, filtration, and heating might be important aspects of water distribution in other contexts, they do not represent the primary role of valves in the system. Valves are primarily designed for flow control, making it easier to manage the distribution network effectively.
