Abstract
A double-seat valve includes a first closing element associated with a first valve seat, a second closing element associated with a second valve seat, a hollow rod connected to the second closing element, a valve rod connected to the first closing element and extending through the hollow rod, a first diaphragm fastened to the hollow rod and to a housing of the valve, and a second diaphragm arranged to seal a channel between the valve rod and hollow rod. The second closing element includes an annular body connected to a supporting section, the annular body and the supporting section designed to clamp the second diaphragm and the connection region to a gap seal against an interior. To simplify the design and to ensure reliable functioning under hygienic conditions, the supporting section has a leakage channel that forms a section of a fluid connection between the connection region and the channel.
