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.
A poppet valve configured comprising a valve housing with line connections and a valve seat formed therebetween in the valve housing, and a closing element, which is axially displaceable in the valve housing and which cooperates with the valve seat, and a membrane extending around the closing element and from the latter up to a fixing site on the housing side. Due to the fact that a spring-elastic and in particular annular element is additionally provided for fixing the membrane under preload on the housing side, and due to the fact that the spring-elastic element is subdivided towards the sealing fixing site into partially circumferential segments having formed thereon extensions, which press the membrane against the cylindrical fixing site and, in so doing, deform the membrane.

Steam trap, aseptic double seated valve, method of operating the steam trap, and filling plant
In a steam trap comprising a seat valve that is adapted to be switched over between an open position for a first discharge state with large throughput and a closed position for a second discharge state with small throughput, the closure element and the seat of the seat valve define, at the closed position, a two-part passage, said passage having a jet cross-section, which first decreases in size in the discharge direction and, subsequently, re-increases in size, and being delimited by the seating area, the sealing face and at least one, only local control groove in the sealing face and/or the seating area. In the aseptic double seated valve the steam trap serves to carry out a flushing cycle as well as a sterilization cycle in a filling plant.
