Introduction to Gate Valve
A gate valve is a type of valve used to control the flow of fluid (liquid or gas) through a pipeline. It operates by raising or lowering a gate (a flat or wedge - shaped disc) to either allow or block the flow. When the gate is fully raised, there is minimal obstruction to the flow, resulting in low pressure drop across the valve. Conversely, when the gate is fully lowered, it forms a tight seal against the valve seats, preventing the flow of fluid. Gate valves are commonly used in applications where a straight - through flow and a full - open or full - closed operation are required, such as in water supply systems, oil and gas pipelines, and industrial process plants.
