The American Society of Mechanical Engineers (ASME) is a professional member organization focused on technical, educational and research issues of the engineering and technology community. In addition to hosting technical conferences and development courses, ASME sets internationally recognized industrial and manufacturing standards that enhance public safety. The subdivision of Pressure Vessels and Piping covers the design, fabrication and operation of valves and other pressure-bearing components and vessels.
ASME publishes hundreds of standards, and many of them are for a specific instrument in a specific application. Some examples of valve standards are listed below.
ASME F1020- Standard Specification for Line-Blind Valves for Marine Applications
ASME B16.33 - EN-Manually Operated Metallic Gas Valves for Use in Gas Piping Systems up to 125 PSI (Sizes NPS 1/2 Through NPS 2)
ASME B16.34 INTERPRETATIONS - EN-Interpretations to B16.34-1996 Valves - Flanged Threaded and Welding End-Includes Interpretation No. 2
ASME B16.10 INTERPRETATIONS - EN-Interpretations to B16.10-1992 Face-to-Face and End-to-End Dimensions of Valves-Includes Interpretation No. 1
