What type of valve is most commonly used in water distribution systems?

The gate valve is most commonly used in water distribution systems due to its design, which allows for minimal resistance to flow when fully opened. This feature makes gate valves particularly suitable for applications where the flow rate needs to be maximized, such as in water supply lines. They provide a tight seal, reducing leakage when closed, and are designed primarily for on/off service rather than throttling, which is an important consideration in systems where flow control is necessary.

In water distribution systems, the ability to isolate sections of the piping for maintenance or repairs is crucial, and gate valves excel in this area because they can be operated with a simple turn of the wheel or handle. This functionality, combined with their durability and ability to withstand high pressure, makes gate valves a preferred choice among engineers and system designers for managing large volumes of water efficiently.
