Air separation is inherently cryogenic distillation and the Special Purpose family sits on the same Type 800 platform whose branch list names Air separation — but the cryogenic sub-variant page does not repeat the name, hence moderate. Transferable point: the compact wafer/lug body minimizes temperature-stabilization time on heat-up/cool-down, which is the cold-box start-up problem in an ASU.

FAQ
Is Cryogenic Butterfly Valve used in Air Separation?
Air separation is inherently cryogenic distillation and the Special Purpose family sits on the same Type 800 platform whose branch list names Air separation — but the cryogenic sub-variant page does not repeat the name, hence moderate. Transferable point: the compact wafer/lug body minimizes temperature-stabilization time on heat-up/cool-down, which is the cold-box start-up problem in an ASU. This is moderate evidence.
