A ring seal for a closing element of a valve, in particular of a valve of a process engineering installation, a seal arrangement including the ring seal, and a valve including the seal arrangement. The ring seal has a ring body defining a longitudinal axis perpendicular to the plane of the ring body; a seal surface on a radially outer surface in relation to the longitudinal axis; and two substantially radially directed leg portions spaced apart from one another in the direction of the longitudinal axis. The two leg portions are connected to one another by a bridge portion extending in the direction of the longitudinal axis, on the radially outer surface of which bridge portion the sealing surface is provided; and, a radially inner surface of the bridge portion is spaced apart in the radial direction from ends of the leg portions which are remote from the sealing surface.
