Which valve is commonly used to control the flow of water in a pipeline?

The gate valve is commonly used to control the flow of water in a pipeline because it is designed for full flow and minimal pressure drop when fully opened. Its functionality allows it to either be fully open or fully closed, meaning it can effectively start or stop the flow of water. This design makes it ideal for applications where a straight-line flow of water and minimal resistance is desired.

Moreover, gate valves have a simple construction that enables easy maintenance and durability, making them suitable for a variety of water distribution systems. While other valves like the butterfly valve or globe valve may also regulate flow, they generally serve different purposes or have different flow characteristics. The check valve is primarily used for preventing backflow rather than controlling flow. Therefore, the gate valve’s specific design and function make it the most suitable choice for controlling water flow in a pipeline.
