Cryogenic breakaway valves generally consist of two halves joined together by a specific connection structure. Under normal operating conditions, the valve remains connected, allowing cryogenic fluids to pass through smoothly. When an unexpected pulling force is encountered, such as a vehicle driving away unexpectedly or a pipeline being pulled by an external force, and the pulling force reaches a set pull-off force, the pull-off valve will disconnect at a preset weak point. Immediately after disconnection, the two halves of the valve will be sealed automatically, preventing large leakage of cryogenic fluid and thus avoiding safety accidents.

Product Description:
The cryogenic breakaway valve is specifically engineered for the safe transfer of cryogenic liquids such as LNG, liquid nitrogen, and liquid oxygen. It features a dual-body structure connected by a precision-designed coupling. Under normal conditions, it allows the smooth flow of cryogenic fluids. In the event of an unexpected pulling force—such as vehicle drive-off or accidental pipeline stress—the valve separates at a predetermined break point, automatically sealing both ends to prevent fluid leakage. This minimizes the risk of spills, equipment damage, or safety hazards.
