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,...
This standard establishes minimum requirements for high-performance butterfly valves, 3 in. (75 mm) through 60 in. (1,500 mm) in diameter, with various body and end types, for raw, potable, and reclaimed water having a pH range from 6 to 12 and a temperature range from 33°-125°F (0...
1.1 This specification provides standard dimensions for manual (lever and gear actuator) butterfly valves installed in shipboard piping systems in NPS 2 to NPS 24, inclusive. 1.2 This specification covers conventional and ANSI B16.34 class butterfly valves of both lug...
This standard specifies requirements for the design, functional characteristics and manufacture of butterfly valves made of thermoplastics materials intended for isolating and control service, their connection to the pipe system, the body materials and their pressure/temperature
This standard establishes minimum requirements for rubber-seated butterfly valve assemblies that are 78 in. (2,000 mm) diameter and larger with flanged ends suitable for fresh and reclaimed water having a pH range from 6-12 and a temperature range from 33°-125°F (0.6°-52°C) and...
