An electronic control brake valve for an airplane comprises a valve body, a cavity, a motor assembly, pressure sensors, a Hall sensor and a central controller, the valve body is located at the front end of the cavity, the motor assembly is installed in the cavity and connected with the valve body, the number of the pressure sensors is three, the pressure sensors are installed on the valve body, and the Hall sensor is connected with the central controller. The number of the Hall sensors is three, the Hall sensors are installed at the positions, corresponding to the motor assembly, of the cavity, the pressure sensor and the Hall sensors are connected with the central controller, the brake valve and the flight control computer are in two-way communication including serial port communication and PWM communication, and the central controller has a fault feedback function. The three pressure sensors and the three Hall sensors are arranged to detect the pressure of the brake valve and the stroke of the motor respectively, so that the electric control system has the performance of redundancy control, the failure rate is effectively reduced, and the brake performance and safety are improved.
