FLAP VALVE


Flap valves and catch valves are specially designed for installation requirements.

Usually installed in catch tank walls to keep them always full by sloshing and prevent pump to suck air in transition.

Also installed on wing ribs to collect usable fuel on center tank and help to manage center of gravity of fuel transfers.

Circular sections can be used for secondary air systems. With seat seal and seal-less designs are available per installation requirements.
