A cryogenic globe valve is a linear-motion throttling valve engineered to regulate extreme sub-zero fluids, such as LNG, liquid nitrogen, and liquid oxygen, at temperatures dropping down to -196°C (-320°F). Rather than utilizing a coolant, it features an extended bonnet that isolates the stem packing from the freezing media by trapping a column of insulating, vaporized gas. This design keeps the packing warm enough to prevent ice formation and external leakage. Fabricated from low-temperature alloys like 316 stainless steel, it utilizes specialized Kel-F (PCTFE) or metal-to-metal seating to resist thermal contraction and seat deformation. Conforming to standards like BS 6364 and ASME B16.34, cryogenic globe valves are the standard choice for air separation plants, LNG terminals, and aerospace fueling skids. Piping specialists and LNG project managers can secure optimal thermal insulation and absolute zero-leakage safety by sourcing certified cryogenic globe valves directly from leading manufacturers in China via our advanced B2B commercial platform.
