The valve comprises a metal casing (1) with a metal seat ring (2) in a passage and acting as the mating element for a shut-off element. The seat ring is cast in the valve casing as an originally separate part. The seat ring on its outer side facing away from the inner side of the opening has a retaining structure which is constructed as an least partially encompassing profiling which has at least one outward protruding connecting section, with the length reaching from its joining point on the seat body to its free end being greater by a multiple than its thickness.
