Gate valves are robust flow control devices used to fully open or close the flow of fluids in pipelines. They operate by lifting a gate out of the fluid path, making them ideal for applications that require minimal flow resistance and a straight-through passage. These valves are best suited for on/off control rather than flow regulation, commonly found in water supply systems, oil and gas pipelines, and chemical processing lines.

Their design offers a tight seal when closed, making them suitable for high-pressure and high-temperature environments. Available in various materials like stainless steel, cast iron, and brass, gate valves can handle different media types and corrosive conditions. Their durable build and reliable performance make them essential in many industrial and commercial infrastructures.
