This document specifies requirements for design, dimensions, material, fabrication and production testing of gate, globe, ball\/plug and butterfly valve design types used as isolation valves and check valves for low-temperature applications.<\/p>\n

This document is applicable to isolation valves for use in low and cryogenic temperature service where the design low-temperature service is -50\u00a0\u00b0C down to \u2013196\u00a0\u00b0C.<\/p>\n

This document does not apply to valves for cryogenic services, designed in accordance with ISO\u00a021011, used with cryogenic vessels.<\/p>\n

Where the requirements of this document vary from those given in the valve product standards, the requirements of this document apply.<\/p>\n

This document is applicable to valves with body, bonnet, bonnet extension or cover made of metallic materials.<\/p>\n

This document is applicable to:<\/p>\n
