What is a gate valve for a water line?

A gate valve is a type of valve used in water lines to start or stop the flow of water. It features a flat gate that can be raised or lowered to control flow, making it ideal for applications where a straight-line flow of fluid and minimal pressure drop are desired. Gate valves are typically fully open or fully closed, rather than allowing for throttling, and are commonly used in pipelines for their durability and reliability.
