The double-seated valve (V) has two sealing rings (17) formed three-dimensionally with one of the two support rings (16,16') that are provided in an annular groove (N) of the valve parts (T,T'). The sealing rings are formed with different diameters (D1,D2) and different bias voltages that are provided in the circumference of the support rings. An independent claim is also included for a sealing for a double-seated valve. |
