Abstract:
The invention relates to a double-seat valve including closing elements (3,4) 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 (2a, 2b), the second closing element (4) by a second partial lift (T2) which acts in the same direction as the opening motion and the first closing element (3) by a first partial lift (T1) which acts in the direction opposite the opening motion travelling into its respective seat cleaning position. The second closing element (4) in its closed position has a stop face (4f) forming a second circumferential edge (U2). A deflection surface (4d) discharges in a front face (4e) of a recess (4b) which is oriented essentially perpendicular to the longitudinal axis of the second closing element (4). The deflection surface (4d) has a contour (K) which runs without bends.
