Proven lifesavers, Stratoflex’s breakaway valves separate under high loads on fluid lines exceeding a predetermined value. Upon separation, the valves automatically seal the fluids in the lines to effectively prevent spills.
Proven lifesavers, Stratoflex breakaway valves separate under high loads on fluid lines exceeding a predetermined value. upon separation, -
the valves automatically seal the fluids in the lines to effectively prevent spills. Breakaway valves are typically used on fuel lines, main fuel -
tanks, extended range aircraft auxiliary fuel tanks, air-to-air refueling systems, and fall-away external tanks. Tank vent lines often use the -
single valve versions. -
The basic design incorporates a butterfly valve mounted to a cam shaft loaded by a coil spring. This design allows for a small envelope, -
lightweight, and minimum pressure drop across the coupling. The mechanism consists of two valve plates and/or a single plate and detent -
post. These are held against each other by spring action until the fuse section separates to allow valve closure. -
An internal sealing sleeve is installed in between the interface joint of the two valve bodies and seals the fluid leakage from internal to -
external before valve bodies are totally separated. This construction permits a clean valve passage, minimizing ice formation and -
contamination. No parts are released to interfere with the valve operation during closure. -
The primary function of breakaway valves is to protect attached fuel system lines from damage due to excessive separation loads.
