API plug valve

The American standard plug valve mainly refers to the design and manufacturing standards of plug valves based on API6D and API599; The structural length standard follows ASME B16.10; The flange connection standard follows ASME B16.5; The pressure temperature rating follows ASME B16.34; The test and inspection standards follow the API 598 standard for producing American standard plug valves. A plug valve is a type of valve that allows the passage port on the valve plug to communicate or separate from the passage port on the valve body by rotating 90 degrees. The opening and closing components are usually plug bodies with through holes, which achieve opening and closing actions through the rotation of the plug body and valve stem. The structure of a plug valve includes the valve plug, valve body, sealing surface, and other parts. The shape of the valve plug can be cylindrical or conical, and the corresponding channel shape is rectangular or trapezoidal. The structural design of the American standard plug valve produced by Shanghai Meiyanyi Pump Valve makes it easy to operate, has low fluid resistance, and has good sealing performance.
