A Low Temperature Shut-Off Valve (LTSOV) with a flange end is a specialized valve designed to automatically stop fluid flow when temperatures drop to a critical low (like -20°F to -40°F or even cryogenic levels), using materials like stainless steel (CF8M/F316) that resist brittleness, connecting securely to pipes via flanges (ANSI/ASME, JIS) for reliable, leak-free performance in extreme cold applications like LNG, air separation, or industrial processes. These valves feature extended bonnets and specialized seals (like PCTFE) to protect internal components from cryogenic fluids, ensuring safety and preventing product loss.
