Low Temperature Butterfly Valves Description
Cryogenic butterfly valve is a valve specially used for extremely low temperature media of -40℃~-196℃. The butterfly plate rotates 90° around the valve axis to open, close or adjust the pipeline fluid. It is widely used in liquefied natural gas (LNG), liquid oxygen, liquid nitrogen, air separation equipment and chemical tail gas treatment. Its core functions include:
Fast opening and closing: simple structure, flexible operation, suitable for rapid shut-off requirements in low temperature conditions.
Low flow resistance design: full-diameter structure reduces medium flow resistance, especially suitable for high-flow cryogenic fluids.
