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 18):
A beverage treatment and/or filling system, comprising:\n an aseptic line for product, the aseptic line including a double seat valve; a filler for filling containers with the product upon passage through the double seat valve in the aseptic line; and a pasteurizer for heat-treatment of the product, the pasteurizer connected to the filler via each of the aseptic line for product and the double seat valve, wherein the double seat valve comprises: a valve housing with two line ports for connecting the valve housing to the aseptic line for product; a safety chamber defined by two valve seats formed between the two line ports; a first fastening element; a first closure element, actuatable by a first valve stem acting against one of the two valve seats; a second closure element, actuatable by a second valve stem acting against another of the two valve seats, the second valve stem at least partially surrounding the first valve stem, each of the first and second valve stem independently moveable along a common valve axis; and a ring-shaped diaphragm seal concentric with the common valve axis, the seal connecting the first valve stem to the second stem to seal against the safety chamber, wherein an outer fastening portion of the diaphragm seal is bent toward the common valve axis by a bending angle of more than 90\u00b0 so that the outer fastening portion abuts against a tapered surface of the first fastening element.
