Emerson valve materials that conform to ASME 16.34 standard class pressure/erature ratings. IMPORTANT INFORMATION FOR TABLES 1. Emerson valves conforming to ASME B16.34 standard have specific pressure/erature limits depending on conponent materials. Use the material reference in the table when determining pressure/erature ratings of valves used in accordance with the ASME standard. 2. Table information is extracted from the Valve Flanged, Threaded, and Welding End, ASME Standard B16.34. These tables must be used in accordance with the ASME standard. The user is advised that a valve used under the jurisdiction of the ASME Boiler and Pressure Vessel Code, ASME Code for Pressure Piping, or governmental regulations is subject to any limitation of that code or regulation. This includes any maximum erature limitation for a material or rule governing the use of amaterial at a low erature. 3. Flanged end ratings terminate at 1 F (538 C). 4. At eratures over 1 F (538 C), use material only when carbon content is.4% or higher. Emerson.com/FinalControl 217 Emerson. All Rights Reserved. VCBUL-4493-EN 18/6
