1. A valve, comprising a sealing element and a valve seat which surrounds a passage opening having a nominal diameter, the valve seat having on a side facing the sealing element a closed circumferential rounding which, in a cross-sectional plane which extends through a central axis of the passage opening, has a seat radius, wherein a distance of a radius center of the seat radius from a wall inner side defining the passage opening is smaller than the seat radius, wherein the seat radius merges into the wall inner side of the passage opening in a transition area, and wherein the transition area comprises a transition rounding having a transition radius which is smaller than the seat radius of the radius center of the seat radius from the wall inner side.
