Abstract: The invention is directed to a gas pressure reducer (2) comprising a body (10) with an inlet (4) intended to be in flow communication with a high pressure gas source; an outlet (6) intended to deliver the gas at a predetermined low pressure; a passage (8) through the body (10) in flow communication with the inlet (4) and with the outlet (6). A resilient element (24) engages with a pressure reducing piston (18) with a through flow path (22) formed by a needle (20). The needle (20) cooperates with a movable seat (16). The outlet pressure acts on the piston (18) in opposite direction than the spring (24) so as to urge the path (22) against the seat (16) in order to reduce the gas flow through the path (22). Pressure setting means comprise an electric actuator (32), such as a stepper motor, which moves the seat (16) along the moving direction of the piston (18) in order to set the predetermined outlet pressure.
