I. Overview

The LNG Breakaway Valve, also referred to as an emergency disconnect valve, is a critical safety component in LNG (Liquefied Natural Gas) transfer systems. It is designed to automatically close and seal off the flow of LNG in the event of an unintended disconnection between the transfer hose and the receiving vessel or terminal.

II. Functionality

  • Automatic Closure: The LNG Breakaway Valve features a mechanism that triggers automatic closure when a certain level of force or displacement is detected. This rapid response ensures that LNG leakage is minimized or eliminated during an emergency.

  • Safety Protection: The valve provides an additional layer of safety by preventing the uncontrolled release of LNG in the event of a hose rupture, vehicle collision, or other unexpected event.

III. Technical Specifications

  • Material: The LNG Breakaway Valve is constructed from materials that can withstand the extreme cold temperatures of LNG, ensuring reliable performance in cryogenic conditions.

  • Design Standards: The valve is designed and manufactured in accordance with international standards and regulations for LNG transfer systems, ensuring compliance and safety.

  • Size and Ratings: The valve's size and flow ratings are tailored to specific applications, based on the volume and pressure of the LNG being transferred.

IV. Applications

  • LNG Terminals and Storage Facilities: LNG Breakaway Valves are commonly used at LNG terminals and storage facilities, where they are installed on transfer arms or loading lines to protect against accidental disconnects.

  • LNG Vehicles and Tankers: In mobile applications, such as LNG-fueled vehicles and tankers, the valve is integrated into the filling system to provide emergency shutoff capabilities.

V. Conclusion

In summary, the LNG Breakaway Valve is a vital safety device for LNG transfer systems. Its ability to automatically close and seal off the flow of LNG in an emergency situation ensures the safety of personnel, equipment, and the environment. Its construction from cryogenic-resistant materials and compliance with industry standards ensures reliable performance in demanding applications.
