Breakaway Valve Now Featuring Manual Quick Disconnect Arm/Re-arm Option

  • No system pressure loss (when disconnected)

  • Negligible pressure drop (in operation)

Our Series 14900 Frangible Quick Disconnect Assembly takes the proven 14000 Series BALVAC® (Ball Valve, Automatic Closure) Breakaway Valve Assemblies one step further.

Frangible Quick Disconnect Assemblies retain all of the proven spring-loaded self-rotating breakaway ball valve design features, while adding a manual reset “quick-disconnect” option.

In this manner, the assembly not only operates as a frangible segment of the pressurized fuel system, it is also quickly engaged or disengaged.

This feature allows rapid installation or removal of additional fuel tanks/bladders or other extended range fuel system components, with no loss of pressurization and while maintaining all frangible system requirements. System-level leak check acceptance test procedures (ATPs) are not required after reconnection.

Existing breakaway valve installations can be retro-fit with a Spectrum® Frangible Quick Disconnect Assembly.

Previous cumbersome installation/removal operations of crashworthy fuel system components or cells can now be streamlined to save time and manpower. Series 14900 Frangible Quick Disconnects are fully qualified and readily available.
