Cryogenic vacuum jacket valves are used to supply smooth cryogenic gas and minimize generation of BOG (Boil-off Gas) by intercepting intrusion of heat being generated inside valves in liquefied flow supply of cryogenic equipment through use of a vacuum system. This research focused on interception of heat exchange with the outside environment. It also considered heat transfer properties on changes in pressure of a vacuum part, radius of a jacket and the length of the jacket which can reduce heat exchange for effective heat transmission control. Therefore, by using the design of experiment, one of the optimization strategy for design of cryogenic vacuum jacket valve, we selected the combination of main design factors. For qualifying the design technology, we compared and analyzed theresults using numerical analysis.
