Abstract:
A double seat valve for aseptic lines for product is described, the valve comprising a valve housing, two line ports arranged on the valve housing for connecting the aseptic lines for product to the valve housing, two valve seats that are formed between the line ports on the valve housing and confine a safety chamber formed therebetween for leaks against the line ports, a first closure element which is actuatable by way of a first valve stem and acts against one of the two valve seats, and with a second closure element which is actuatable by way of a second valve stem and acts against the other of the two valve seats. T first valve stem at least in part surrounds the second valve stem, so that both are movable independently along a valve axis. The first valve stem is connected to the second valve stem by way of a diaphragm seal formed in a ring-shaped manner around the valve axis A for sealing against the safety chamber, characterized in that an outer fastening portion of the annular diaphragm seal is bent inwardly toward the valve axis by a bending angle of more than 90°, so that it abuts against on a tapered surface of a first fastening element.

Claim (Index 1):
A double seat valve, comprising:\n a valve housing; two line ports arranged on said valve housing for connecting aseptic lines for product to said valve housing; two valve seats formed between the two line ports on said valve housing, the two valve seats defining a safety chamber formed there-between for leaks against the two line ports; a first closure element, actuatable by a first valve stem, acting against one of the two valve seats; and a second closure element, actuatable by a second valve stem, acting against an other of the two valve seats, wherein said first valve stem surrounds said second valve stem, at least in sections, so that both are movable independently along a valve axis, and wherein said first valve stem is connected via a diaphragm seal, which is formed to have a ring shape around said valve axis, to said second valve stem for sealing against said safety chamber, and wherein an outer fastening portion of said diaphragm seal is bent inwardly toward said valve axis by a bending angle of more than 90\u00b0, so that it abuts against a tapered surface of a first fastening element.
