The seat surface (5) has a coating of thermal stress bearing elastomer, e.g. fluorcaoutchouc. The valve body (2) has a peripheral rubber ring (11) to generate a sealing action between exhaust gas return pipe and valve body, and for dampened bearing of valve body in the pipe. The clamping surface and the leaf spring element (6) have a centering aperture, which act with a centering nose of the counter holder (7).",
