A multi-stage adjusting damping valve as well as a shock absorber and suspension system using the damping valve are provided. The multi-stage adjusting damping valve comprises a throttle valve, an overflow valve and a multi-stage pilot valve. The multi-stage pilot valve comprises a mechanical regulating valve and a plurality of high-speed switch electromagnetic valves having different throttle hole diameters. The damping valve is connected between a rod cavity and an oil storage cavity of the shock absorber by means of a middle cavity, and the multi-stage damping rapid regulation of the shock absorber is achieved through high-frequency opening and closing of a high-speed switching electromagnetic valve, and in comparison, the machining precision, the manufacturing cost and the control and calibration difficulty of the present disclosure are greatly reduced.
