ANSI cast steel gate valves are control components in fluid transport systems, providing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, and pressure relief. Valves used in fluid control systems range from the simplest ANSI gate valves to various ANSI valves used in highly complex automated systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media.
