Abstract (en)

[origin: WO2011029849A1] The invention relates to a ring seal (32) for a closure element (22) of a valve (20), in particular a valve (20) of a technical process system, comprising a ring body (34) defining a longitudinal axis (36) perpendicular to the plane of the ring body (34), and comprising a sealing surface (42) at a radially outer surface (40) with respect to the longitudinal axis (36). The ring body (34) is constructed in multiple layers, wherein a radially outer first layer (38), the sealing surface (42) being present at the radially outer surface thereof, is made of a sealing material, and wherein a second layer (46) connects to the side of the first layer (38) facing away from sealing surface (42), comprising a different spring characteristic in the radial direction and/or a different material than the first layer (38). The invention further relates to a sealing arrangement (30) having such a ring seal (32) and a valve (20) having such a sealing arrangement (30).
