Please let me know different Codes / Standards used for design of Pressure Reducing Valves?The AWWA standards for the water works industry are different than the API standards for oil and gas industry such as API Spec 6D and Std 598. A recent post includes the MSS standards. ASME publishes many applicable standards. Start with B16.34 and B16.10.Perhaps you could also clarify which pressure reducing valves you are specifically addressing. Examples could be self-contained pressure regulators, control valves, pressure safety relief valves or other valves that control pressure downstream. ISA publishes control valve standards. PIP publishes valve standards. UL 842 is a standard for vlammable fluid valves.ASTM publishes many material standards and a few related to valves.Basically I wanted to know international standard (preferably ASME)to calculate Valve shell wall thickness, crotch area calculations etc.I guess you meant EN 12516-2 and the only ASME standard I know about that at least handles crotch calculations simliarly is ASME Section III, Section 1, NB (paragraph NB-3545). Oh and ASME B16.34 appendix V uses a similar method for limited class valves, but that is only for <= 2?" valves.EN 12516-1 (Tabulation method for steel valve shells) on the other hand is very similar to ASME B16.34 (I would even call it a copy-paste job)
