Trying to qualify bronze balancing valves to b16.34. All materials are EN and material certs are EN no mention of ASME or ASTM. To get CRN would it be possible to show equivalence of mechanical properties and use the lesser tensile values and allowable stresses to determine body wall min thickness? I know it won't permit a B16 34 designation, but is this a sound approach? Why can't Asme reference EN materials and permit these stronger materials to be used?
