Abstract
Industrial valves are mechanical devices used to manipulate and manage fluids in an industrial plant. They are used in several applications, being considered of high criticality, those that involve the use in low temperatures. For these applications, so-called cryogenic valves are used, which are designed with specific geometry. The metallic and polymeric materials used are carefully selected to suit the contact with cryogenic fluids, where temperatures can vary from -46 °C to -254 °C. This article presents a literature review on the main concepts of a cryogenic ball valve design, presenting constructive aspects, normalization, related works, and finally, a case study related to a product approval test is presented. Thus, this work presents itself as complementary and auxiliary literature for students and professionals in the field related to the project, qualification tests, and the use of cryogenic valves, contributing yet to a better specification and use of these devices, aiming at a longer useful life and safety for the operation and the environment.
