Scope

Scope: This document specifies the structural type, technical requirements, materials, performance requirements, inspection and testing, inspection rules, marking, packaging, and storage and transportation requirements for butterfly valves used for liquid hydrogen (hereinafter referred to as "butterfly valves"). This document applies to butterfly valves with nominal pressures of PN16 to PN50, nominal sizes of DN15 to DN800; pressure classes of Class150 to Class300, and nominal sizes of NPS1/2 to NPS32, for liquid hydrogen or cold hydrogen with a medium temperature not exceeding -196°C and not lower than the boiling point of hydrogen at standard atmospheric pressure, used with welded or flanged connections.
