A pressure-reducing system for a breathing apparatus including: i) a supply conduit for supplying a pressurised breathable gas; ii) a suction mouthpiece for a user to breathe in the breathable gas; and iii) a valve operatively interposed between the supply conduit and the suction mouthpiece. The valve includes: —an inlet, —an outlet; —a shutter permits or prevents the passage of the breathable gas from the inlet to the outlet; and—a pressure balancing chamber, the shutter being interposed between the inlet of the valve and the balancing chamber; the shutter defining a conduit that places the inlet of the valve and the pressure balancing chamber in fluid communication. The pressure-reducing system further includes iv) a movement system for moving the pressure balancing chamber towards the inlet for the breathable gas to push the shutter from the first position to the second position.
