Flux Valves

A Flux Valve is a magnetic sensory device that electrically transmits information to an aircraft's compass system regarding its orientation relative to Earth’s magnetic field. This information, in the form of three separate electrical signals tied to a common return, is used to generate a visual indication to the flight crew regarding the heading of the aircraft relative to magnetic north.

Our flux valves are used on a number of commercial and military aircraft, such as the Embraer 135 / 145 and the Boeing F18 E/F. 

We have recently obtained TSO certification on a new design.   The revised design utilizes smaller gimbals mounting pins to ensure:

• Less resistance
• Faster response / recovery time to attitude changes.
