Scope

Main technical content: This document specifies the structural type, technical requirements, performance requirements, inspection and testing methods and requirements, factory inspection and type testing, marking, packaging, and storage and transportation requirements of the super-temperature cut-off emergency shut-off valves (hereinafter referred to as "emergency shut-off valves") used for liquid hydrogen media. This document is applicable to nominal pressures of PN16 to PN160, nominal sizes of DN15 to DN300, pressure grades of Class 150 to Class 900, nominal sizes of NPS1/2 to NPS12, and 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. The emergency shut-off valves consist of welded or flanged connections, valves, pneumatic actuators and their control accessories, fusible alloy plugs, and other components. Other forms of emergency shut-off valves can be implemented as a reference.
