Introduction to Gate Valve
A gate valve is a type of valve used to control the flow of a fluid (liquid or gas) by raising or lowering a gate or wedge-shaped disc within the valve body. The gate moves perpendicular to the flow direction of the fluid. When the gate is fully raised, the fluid can flow freely through the valve with minimal obstruction, providing a straight - through path. When the gate is fully lowered, it blocks the flow completely. Gate valves are commonly used in various industries such as oil and gas, water treatment, power generation, and chemical processing due to their ability to provide a tight shut - off and low flow resistance when fully open.
