The invention discloses a high-pressure air proportional pressure reducing valve. The high-pressure air proportional pressure reducing valve comprises a valve body, a spring seat, a spring, an upper valve element, a lower valve element and a lower end cover. The spring seat serving as an upper end cover is screwed into the valve body through threads, and a lower end cover is fixed in the valve body through threads; an upper valve element and a lower valve element are arranged in the valve body, the upper end of the upper valve element abuts against one end of the spring, and the lower end of the lower valve element is inserted into the lower end cover. The upper valve element and the lower valve element are connected and fixed through threads to form an integral valve element. A second sealing ring is embedded between the upper valve element and the lower valve element, and a gap between the second sealing ring and the valve body is a valve port; high-pressure gas flows in from the gas inlet and flows out fro
