Cryogenic sealing
WebCryogenic Butterfly Valves The triple-offset butterfly valve is an ideal option for cryogenic service. This is due to its non-friction, metal-to-metal seal that provides bubble-tight shut-off and the long-term integrity of the sealing mechanism. Additionally, they offer quick opening and closing action and are the ideal choice for remote operation. WebJul 13, 2024 · From a sealing standpoint, cryogenic applications are problematic due to the extreme cold temperatures that cause expansion and contraction of the bolted connection. Elastomer-based materials become hard and brittle when exposed to low temperatures and are not recommended to exceed -100 F (-73 C).
