An emergency breakaway valve is a safety device installed at the front end of fluid loading/unloading equipment, primarily used in the loading/unloading of chemical media such as petroleum products, liquefied petroleum gas, and natural gas. This device employs a spring-loaded check valve and mechanical trigger mechanism to automatically disconnect connections during unexpected tanker movements or emergencies, achieving leak-free separation. Its structure incorporates a clamping mechanism, breakaway mechanism, and bidirectional sealing components, enabling self-sealing protection without external power after activation.
By 2025, a product series has been developed with nominal diameters of DN25, 50, and 80, and pressure ratings ranging from PN0.6 to 6.4MPa, accommodating temperatures from -100°C to 250°C.
