Features and Functions of Loading Arm Arm Break Valve
Breakaway valve for loading arms is a safety device that automatically disconnects and seals the arm when excessive tensile force occurs, preventing leakage and equipment damage.
High Sensitivity: Designed to activate quickly (typically within milliseconds) when a preset tensile force is exceeded, ensuring timely disconnection before equipment damage occurs.
Reliable Sealing: Equipped with dual-sealing structures (both in the valve body and the disconnected interface) to prevent leakage of hazardous media during and after disconnection.
Durable Construction: Made from corrosion-resistant materials (such as stainless steel or alloy) to withstand harsh operating environments, including exposure to chemicals, high/low temperatures, and pressure fluctuations.
Compact Design: Integrates seamlessly with loading arm structures without adding excessive weight or bulk, maintaining operational flexibility.
Reusable: After activation, the valve can be reset and reinstalled (with proper inspection and maintenance), reducing replacement costs.
Functions:
Emergency Disconnection: Automatically separates the loading arm from the tank (e.g., tank truck, ship) when unexpected tensile forces occur-such as vehicle/ship movement, collision, or excessive arm extension-preventing structural damage to the loading arm or tank.
Leak Prevention: Immediately seals both ends of the disconnected interface upon activation, minimizing spillage of flammable, toxic, or corrosive media, thus reducing safety risks (e.g., fires, environmental pollution) and operational losses.
Equipment Protection: Mitigates mechanical stress on the loading arm, pipelines, and related components, extending their service life and reducing maintenance frequency.
Safety Compliance: Helps meet industry safety standards (e.g., API, ISO) by providing a critical failsafe mechanism for liquid transfer operations in petroleum, chemical, and hazardous material handling sectors.
