Ball valve operating temperature

I see lots of pictures on instagram of people who will place their stainless solvent tank on dry ice and complete and extraction. Dry ice( or a mixture) can reach temperature ranges lower then what ball valves are limited to.


Is there some special ball valve that everyone is using? Would running this way cause problems over time?

Typically the bottom of a collection vessel is put in dryice, or a single column pre-run. Very rarely would a ball valve make direct contact with dryice, and thus I doubt the ball valves would ever reach below -60(or whatever most ball valves are rated at).

Sometimes it can be an issue . And yes they do make cryogenic ball valves if it does become an issue for you.

I use the BV that came w my system from BVV & it does not reach crypto temps despite my collection pot reaching temps of -50 or lower than I can detect w my laser thermometer.
