Introduction to ANSI Gate Valve
ANSI (American National Standards Institute) gate valves are a type of valve widely used in various industries. These valves are designed to control the flow of fluid by raising or lowering a gate inside the valve body. The gate can be fully opened to allow unrestricted flow or fully closed to stop the flow completely. ANSI gate valves are known for their reliable sealing performance, low pressure drop when fully open, and suitability for a wide range of fluids, including water, steam, oil, and gas. They are commonly used in pipelines in power plants, refineries, chemical plants, and other industrial facilities.
