Abstract
The invention relates to a double-seat valve including closing elements () which can be transferred independently of one another by a respective partial lift gap-wide into a seat cleaning position for purposes of flushing their coaxial seat surfaces (a,b), the second closing element () by a second partial lift (T) which acts in the same direction as the opening motion and the first closing element () by a first partial lift (T) which acts in the direction opposite the opening motion travelling into its respective seat cleaning position. The second closing element () in its closed position has a stop face (f) forming a second circumferential edge (U). A deflection surface (d) discharges in a front face (e) of a recess (b) which is oriented essentially perpendicular to the longitudinal axis of the second closing element (). The deflection surface (d) has a contour (K) which runs without bends.
