Hello,

Wondering if anyone can suggest a good valve selection handbook or guidance on selection of cryogenic valves?

Specifically looking at cryogenic on-off valves in sizes 8” and above and pressure classes 300# to 1500#.

Interested in user experience with globe, ball and butterfly valves at these sizes and pressure classes and understanding of industry trends & norms, in terms of optimising performance and cost.

Any advice and tips appreciated.

Cryogenic at that pressure??

Why?

The whole point of cryo is to operate at low pressure.
