Test of „Flying Hydraulic Systems“

A typical application example is the test of so-called Flow Control Valves which are often used in civil aviation, e. g. in air conditioning systems of larger passenger planes.

Such Flow Control Valves are not only made of electronic, but also of hydraulic components, which have to be tested regularly. This is the only way for a pilot to adjust the status of a valve safely and to monitor it in the cockpit.

For testing the Flow Control Valves the hydraulic lines are connected via WALTHER couplings. Monitoring air pressure differences, the pilot can test, if all functions remain inside allowable limits.
