A regulator first stage for two-stage underwater breathing apparatuses includes a reduction chamber communicating with a high-pressure gas supply through a balance valve, which is influenced by the pressure of the external environment by a balance diaphragm that, by way of a suitable actuator, acts on the valve. The reduction chamber includes one or more medium pressure outlets, having axes parallel to the operating axis of the balance valve. In one configuration, one or more medium pressure outlets are also provided having axes orthogonal to the operating axis of the valve.
