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) within the valve body. When the gate is fully raised, the valve is open, allowing unrestricted flow of the fluid. When the gate is fully lowered, it blocks the flow path, effectively shutting off the fluid flow. Gate valves are widely 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 pressure drop when fully open.
