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 the use of a vacuum system. This research focused on the interception of heat exchange with the outside environment. It also considered heat transfer properties on changes in pressure of a vacuum part, a radius of a jacket, and jacket length, which can reduce heat exchange for effective heat transmission control. Therefore, by using the design of the experiment, one of the optimization strategies for the design of cryogenic vacuum jacket valve, we selected the combination of main design factors. For qualifying the design technology, we compared and analyzed the results using numerical analysis.
