The invention relates to a gas valve unit for adjusting gas volume flows to a dual circuit gas burner (1) of a gas appliance, in particular a gas cooking appliance. The gas valve unit comprises a gas inlet (3) and two gas outlets (11, 12). According to the invention, the gas volume flow fed to the first gas outlet (11) can be adjusted in a plurality of stages and the gas volume flow fed to the second gas outlet (12) can be adjusted in a plurality of stages. The gas valve unit comprises at least two first on-off valves (15) for adjusting the gas volume flow fed to the first gas outlet (11), and at least two first throttle points (17), preferably at least three first on-off valves (15) and at least three first throttle points (17). Similarly, the gas valve unit comprises at least two second on-off valves (16) for adjusting the gas volume flow fed to the second gas outlet, and at least two first throttle points (18), preferably at least four second on-off valves (16) and at least four second throttle points (18). At least one magnetically acting body, preferably at least one permanent magnet, is provided for controlling the on-off valves (15, 16) and is displaceable relative to the on-off valves (15, 16). |
