Fuel return valve is an important part of aviation engines. It achieves the cooling of integrated drive generator by regulating the amount of fuel in the oil cooler of integrated drive generator. Fault modeling and simulation of fuel return valve can provide targeted guidance for its maintenance. This paper establishes fuel return valve's mathematical model which includes the flow control valve, the electromagnetic valves and other components. The model is simulated using Simulink, and the
