Introduction to Gate Valves
Gate valves are crucial components in various industrial piping systems. They are designed to control the flow of fluids (liquids or gases) by using a gate or wedge that moves up and down to either block or allow the passage of the medium. Gate valves offer a full - bore opening when fully open, which minimizes flow resistance and pressure drop, making them suitable for applications where a straight - through flow is required. They are widely used in industries such as oil and gas, power generation, water treatment, and chemical processing.
