BS EN 1626:2008 Cryogenic vessels. Valves for cryogenic service

BS EN 1626 specifies the requirements for the design, manufacture and testing of valves for cryogenic service. It applies to valves for operation with cryogenic fluids below -10 °C as well as at ambient conditions to allow for start-up and run-down.

BS EN 1626 specifies additional requirements for cryogenic service for the appropriate valve product standard.

BS EN 1626 applies to sizes up to DN 150 including vacuum jacketed cryogenic valves.

BS EN 1626 is not applicable to safety valves and valves for liquefied natural gas (LNG). It is intended that the valve be designed and tested to satisfy a pressure rating (PN or Class). Valves may then be selected with a PN or Class equal to or greater than the maximum allowable pressure (PS) of the equipment with which it is to be used.
