ANSI vs DIN Flange Valve
ASME B16.5 Class vs EN 1092 PN flanges — bolt circles, gaskets, EPC mismatch risk.
Selection notes
Match the construction to media, temperature, pressure class, and end standard. EPC BOQs often mix ANSI and DIN language — confirm flange facing and bolt circle before ordering.
Supreme Valves India quotes both constructions from the same package RFQ when sizes and ratings are listed clearly.
