The American Standard NPT Globe Valve is a globe valve designed and manufactured according to American standards, primarily characterized by its NPT (National Pipe Taper) internal threaded connection. This connection method ensures a tight and reliable seal between the valve and the pipeline. The valve controls the flow of fluid media by lifting or lowering a disc, making it suitable for water, steam, oil, gas, and certain corrosive media. American Standard NPT globe valves feature a simple structure, easy maintenance, and excellent sealing performance, making them widely used in various general industrial pipeline systems, especially prominent in small and medium-bore pipelines.
