| Subject of the standard: | 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. This document is applicable to isolation valves for use in low and cryogenic temperature service where the design low-temperature service is -50 °C down to –196 °C. This document does not apply to valves for cryogenic services, designed in accordance with ISO 21011, used with cryogenic vessels. Where the requirements of this document vary from those given in the valve product standards, the requirements of this document apply. This document is applicable to valves with body, bonnet, bonnet extension or cover made of metallic materials. |
