Cryogenic Butterfly Valve

A cryogenic butterfly valve is a high-performance quarter-turn rotary valve specifically engineered to open, close, and regulate the flow of liquefied gases—such as LNG, liquid nitrogen, liquid oxygen, and liquid hydrogen—at extreme temperatures down to minus 196 degrees Celsius. Cast or forged from dual-grade austenitic stainless steel to maintain excellent impact toughness in sub-zero environments, the valve utilizes an extended stem design with integrated drip plates to isolate its modular packing seal from the deep-freeze zone, keeping the packing at ambient temperature and preventing dangerous stem leaks. to rigid benchmarks like BS 6364, ISO 28921, and ASME B16.34, these low-maintenance valves are standard specifications across LNG storage terminals, marine bunkering networks, and air separation plants. Cryogenic infrastructure procurement managers and LNG pipeline contractors can eliminate sub-zero leakage and drastically reduce maintenance downtime by importing certified cryogenic butterfly valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
