Ships and marine technology. Butterfly valves for use in low temperature applications. Design and testing requirements Ingestion-build-132972 Requirements on designationWhat is this standard about? This document specifies requirements for design, manufacture, and test methods of cryogenic butterfly valves in order to have an excellent quality leakage stability in a very low temperature service (196 C to 80 C). It is applicable to valves of nominal sizes: DN: 80, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600 corresponding to nominal pipe size (NPS): 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24.
