How is thermal expansion and contraction taken into account in the design of valves? How is this issue controlled in actual use?

As the title suggests, how is the issue of thermal expansion and contraction taken into account when designing valves? In actual valve use in reality, how is the issue of thermal expansion and contraction controlled? Are there any professional materials or explanations.....
Low-temperature valves require solution treatment and cryogenic treatment to address this issue. On other occasions, one has to wait for the experts to explain.
Low-temperature valves are manufactured using cryogenic processes
Different structural measures are employed for various types of valves; in addition, factors such as the material’s coefficient of expansion, appropriate fit tolerances, and the material properties under temperature differences are taken into account.
Regarding valves. Cryogenic treatment. Regarding pipelines. Reserve elbow pipes or compensators. But whether it’s pipes or valves. All require a relatively stable temperature. Rapid temperature changes are not allowed.
Soft joints or expansion joints can be considered for the pipelines, and the bolt preload on the valves should be appropriate.
This is a very complex matter; it’s not as simple as cryogenic treatment. You can search for relevant papers online – only people from valve manufacturing companies can answer questions about this
