Provided are a three-level pressure transformation relay valve and a three-level pressure transformation relay valve kit thereof. A counter voltage air chamber A and a counter voltage air chamber B which are of different sizes are arranged in a lower valve body of the three-level pressure transformation relay valve, and when the three-level pressure transformation relay valve is communicated with a voltage regulating pipeline, different counter voltages can be produced in the two air chambers respectively, so that three-level pressure transformation of the relay valve is achieved to adapt different load conditions. The three-level pressure transformation relay valve kit makes a three-grade change-over switch be combined with the three-level pressure transformation relay valve, the operating conditions of the relay valve are regulated through the three-grade change-over switch, and the switch among the three levels is achieved; the structure is simple and practical, and the stability is good.
