Butt welding end Cryogenic Stainless Steel Globe Valve for LNG / LN2 / LO2

The Cryogenic Stainless Steel Globe Valve is a specialized solution for extreme low-temperature fluids like LNG ( -162℃) and LN2 ( -196℃). It features an extended bonnet (gas column) to isolate the stem packing from the liquid phase, preventing ice formation. The Butt Welding (BW) ends ensure a permanent, leak-proof joint, vital for high-integrity cryogenic skids. Constructed from Stainless Steel (CF8/CF8M), it maintains high ductility and toughness at absolute zero temperatures.
