A gate valve is a type of valve used to completely stop or allow flow in a pipeline by raising or lowering a solid barrier (the gate) into the path of the fluid. It is primarily designed for on/off control rather than flow regulation. When the valve is fully open, the gate is entirely lifted, allowing unobstructed flow with minimal pressure drop. When closed, the gate seals tightly to stop flow entirely. Gate valves are most effective in systems where the valve remains either fully open or fully closed for extended periods. They are not ideal for throttling purposes because the partially open gate can vibrate, causing wear and potentially damaging the valve. These valves are widely used in water supply systems, oil and gas pipelines, and industrial applications due to their robust construction and ability to handle high pressures and temperatures. Common materials include cast iron, stainless steel, and brass, with options tailored to specific media and environments. Gate valves are known for their durability, tight sealing, and long service life, making them a preferred choice in many heavy-duty applications.
