A remote-control high-pressure air pilot balance stop valve mainly solves the technical problems of stop valve remote control and the like. The technical proposal is as follows: a pilot valve with a control actuator is arranged on a main valve body, a sealed air chamber b is formed above the main valve body and is connected with an air guide hole of the pilot valve by an upper air guide hole, theair guide hole is connected with an upper air chamber, the main valve body is provided a lower air guide hole cover which is connected with a lower air chamber of the pilot valve body, and a pilot valve core of a valve seat hole of the pilot valve body which is opened or closed by a control valve of the control actuator is arranged between the upper air chamber and the lower air chamber of the pilot valve. The stop valve is applicable to high-pressure large-diameter pipelines.
