The invention belongs to the technical field related to air pressure control, and discloses an electric drive direct-acting type high-pressure pneumatic pressure reducing valve and an optimization design method thereof.The pressure reducing valve comprises a main valve assembly and an overflow valve, and the overflow valve is embedded in the main valve assembly; the overflow valve is used for automatically opening and exhausting when the pressure reducing valve needs to release pressure or the outlet pressure exceeds the set pressure, so that pressure release is completed or the outlet pressure is stabilized at the set pressure; the driving force of the overflow valve is the difference between the pressure of compressed air borne by the two opposite ends of the main valve piston of the main valve assembly and the driving force of the motor. Through the improvement of the structure, quick response can be achieved, the pressure regulating precision is high, and the structure is compact. 本发明属于气压控制相关技术领域，其公开了一种电驱
