Installing Emergency Breakaway Valves (EBVs) at refueling stations (such as CNG/LNG stations) is a critical safety measure. Their primary functions and benefits include:

1. Preventing Major Accidents:

• Emergency Disconnection: If a vehicle drives away with the dispenser nozzle still connected (e.g., driver error), the valve is designed to break away at a predetermined force.

• Instant Sealing: Immediately after separation, the valve automatically seals both sides of the broken fuel line (the dispenser side and the vehicle side). This double-sealing action instantly stops the flow of gas or liquid, preventing a massive and dangerous spill.

2. Enhancing Safety and Environmental Protection:

• Mitigating Fire and Explosion Risks: By preventing large-scale releases of flammable fuels (like CNG, LNG, gasoline, or diesel), the valves drastically reduce the potential for fires, explosions, or vapor cloud formation.

• Preventing Environmental Contamination: They effectively avoid significant soil or groundwater pollution from fuel spills.

3. Protecting Equipment and Infrastructure:

• Minimizing Damage: The controlled breakaway protects expensive station equipment, such as dispensers, hoses, and piping, from being dragged or ruptured. It also prevents damage to the vehicle's fuel system.

• Reducing Downtime and Costs: By containing the incident and minimizing damage, valves help ensure the station can resume operations more quickly after an event and avoid costly repairs or environmental cleanup.

4. Key Safety Features:

• Fail-Safe Mechanism: They are designed to operate automatically without requiring external power or human intervention.

• Precision Activation: The breakaway force is carefully calibrated to be low enough to activate before hoses or other components are damaged, but high enough to withstand the normal forces of refueling operations (like hose handling or pressure surges).

In summary, the breakaway valve acts as a crucial safety fuse at the refueling point, ensuring that an accidental drive-away event results in a controlled and sealed shutdown rather than a catastrophic incident.
