1. Practical Applications
Emergency Breakaway Valves (EBVs) are widely used in scenarios involving fluid transfer between mobile and fixed facilities to ensure safety. Key applications include:

• Loading/Unloading Operations: Installed on loading arms or hoses at oil terminals, chemical plants, and LNG/LPG stations to prevent spills if a tank truck accidentally drives away during transfer.

• Refueling Stations: Used in CNG/LNG, gasoline, and diesel dispensers to automatically seal fuel lines if a vehicle moves off with the nozzle still attached.

• Marine and Rail Loading: Applied in ship-to-shore or railcar loading systems to protect against sudden disconnection caused by vessel movement or operator error.

• Chemical and Industrial Processes: Deployed in hazardous fluid handling systems to mitigate risks from unintended equipment separation.

2. Common Issues and Troubleshooting

• Failure to Activate:

  • Cause: Incorrect installation (e.g., misalignment, excessive torsion), clogged valves, or damaged mechanical components.

  • Solution: Verify installation orientation and alignment, clean or replace internal parts, and ensure the breakaway force meets specifications.

• Leakage After Activation:

  • Cause: Worn seals, foreign object damage, or improper valve reassembly (for reusable types).

  • Solution: Replace seals, inspect valve integrity, and follow manufacturer guidelines for resetting/replacing the valve.

• False Activation:

  • Cause: Excessive vibration, accidental impact, or incorrect breakaway force calibration.

  • Solution: Isolate the valve from external stresses, recalibrate to the required force threshold, and inspect for environmental factors.

• Corrosion or Mechanical Wear:

  • Cause: Exposure to harsh chemicals, moisture, or abrasive materials.

  • Solution: Implement regular inspections, use corrosion-resistant materials (e.g., stainless steel), and replace valves showing signs of degradation.

• Post-Activation Reset Challenges:

  • Cause: Lack of training or complex reset procedures (especially for hydraulic types).

  • Solution: Train personnel on proper reset/rebuild protocols and maintain spare parts kits for quick recovery.

3. Maintenance Best Practices

• Conduct regular visual inspections for damage, corrosion, or leaks.

• Test functionality periodically using manufacturer-approved methods (without triggering actual activation).

• Ensure replacement parts meet original specifications to maintain reliability.

By addressing these issues proactively, EBVs can consistently deliver critical safety protection in high-risk fluid transfer operations.
