Unloading valves are pressure-control devices that are used to dump excess fluid when the line pressure reaches a pre-set value.  A typical application is for the Helicopter In-Flight Refueling System (HIFR).  Once the fuel tank is full the unloading valve will open returning additional fuel back to the sump tank.
