The invention relates to a double seat valve with cleanable seats, which is improved with regard to the prior art in that a discharge possibly free of turbulence of the seat cleaning flow into and out of the leakage cavity is ensured and a direct admission of the seat areas, which would increase pressure, is safely avoided. This is achieved in that the second closing element (4) abuts in its closed position at the transition area (2e; 2e*) with a stop face (4e) arranged at a front face of its cylindrical lug (4*) and that directly adjacent to the first seat (2a, 2g), that a central recess (4d) is provided in the front face of the second cylindrical lug (4*), which starts radially on the outside with a rotationally symmetrical diversion area (4b) (starting point of the contour (K)) and is bounded at the front by a front face (4c) oriented substantially vertically towards the longitudinal axis of the second closing element (4), the diversion area (4b) leading out into the front face (4c) (leading out point of the contour (K)), that the diversion area (4b) and the stop face (4e) form a second circumferential edge (U2), which is directly adjacent to a first end section (2g) of the first seat (2a) in the closed position of the second closing element (4), that, viewed in vertical centre section, the diversion area (4b) comprises a contour (K) with unbent shape, wherein a direction vector in the leading out point of the diversion area (4b) points into a discharge bore (3d) centrally arranged in the first closing element (3), without colliding with the first closing element (3) in the area of its areas bounding the leakage cavity (5) or of the intermediate seal (8; 8*) and without forming impact pressure thereby, and that a frontal boundary of the first closing element (3) directed towards the leakage cavity (5) has an axial safety distance (x) from the direction vector at an outlet point of the transition area (2e) formed as a first circumferential edge (U1) into the first end section (2g).
