The invention discloses a remote control emergency brake valve for a railway propulsion vehicle. The remote control emergency brake valve comprises a valve body, a valve element, a coil, a control circuit board, a relay and a power source, an air duct penetrating through the two ends is formed in the valve body, one end of the air duct is used for being connected with a train main air pipe, and the other end of the air duct is used for exhausting air; the power supply is electrically connected with the control circuit board, the control circuit board is electrically connected with the relay, and the relay is electrically connected with the coil; and the coil is arranged on the upper end face of the valve body, one end of the valve element penetrates through the coil and extends into the air duct from the upper end face of the valve body to seal the air duct, one end of the valve element extends out of the coil, and when the coil is powered on, the coil can drive the valve element to move upwards to open the air duct. The control circuit board is used for receiving a control signal transmitted by the remote controller, controlling the relay to be closed according to the control signal and further controlling the coil to be powered on or off. The remote control emergency brake valve is convenient to operate, potential safety hazards are reduced, shunting operation safety and personal safety are guaranteed, safe development of companies is promoted, and great economic benefits are achieved.
