A purge valve for a mounted assembly for a vehicle consisting of a wheel comprising a rim and of a tire, the valve comprising a body associated with the rim and a piston able to move with respect to the body between a closed position and a purge position and the valve being normally closed. The opening of the valve is obtained by the moving of the piston into the space radially external to the rim, the opening being obtained by action of a control force on the piston, exerted from the space radially internal to the rim, and provided by compressed air led from the space radially internal to the rim to the radially interior surface of the piston and the compressed air led from the space radially internal to the rim to the radially interior surface of the piston being at a pressure lower than or equal to that of the mounted assembly.
