1. Table information is extracted from the Valve–Flanged, Threaded, and Welding End, ASME Standard B16.34-2013. These tables must be used in accordance with the ASME s tandard. The
ASME standard states in paragraph “2.1.3 Special Class Valves. Threaded or welding end valves that conform to all the requirements of para. 2.1.2 and in addition have successfully passed the
examinations required by Section 8, may be designated Special Class valves.” The standard also stipulates that, “Special Class ratings shall not be used for flanged end valves.” Information
