Gas pressure regulator valve adapted to a household appliance for the supply of a flow of NG or LPG gas that comprises a valve body (11) with an inlet conduit (12), an outlet conduit (13) of the gas at a nominal pressure, a pressurised chamber (14) connecting both conduits through a regulation valve (39,40), a diaphragm (22) connected to the valve member (39), a closure cap (26) and means (26-29,19,23,35) for the adjusting of the nominal pressure for NG or LPG gas. The adjusting means include a prestressed adjusting screw (35) on the diaphragm (22), a guide means (28) of the rotation on the cap (26) and a stopper means of the rotation on the body (11). The pressure value is adjusted by the rotation of the cap between two positions.
