A device is described for stopping and restoring the flow of pressure reducers, comprising: a main body (1) housing a check valve (7); a cover (2), that houses a pressure-regulating screw (10) and its related spring (12); and a vessel (3) connected to the main body (1), the vessel (3) housing a pin (5') connected to a knob (5), the pin (5') being adapted, by exerting a rotation of the knob (5), to rise and, by means of an interposed washer (4), to blocks a shutting valve (6) contained in the body (1), thereby stopping the pressure flow, the pressure reducer thereby also performing the function of intercepting tap.
