Abstract:
An aseptic double seat valve has a housing, which has connections for two pipe conduits. A first valve seat and a second valve seat are arranged spaced apart from one another in the direction of a longitudinal axis in the housing between the connections for the two pipe conduits. A first closing body interacts in a sealing manner with the first valve seat, and a second closing body interacts in a sealing manner with the second valve seat. A first elongate valve stem, which is of hollow design is connected to the first closing body, and a second elongate valve stem, which extends through the interior of the first valve stem, is connected to the second closing body. A diaphragm, which has a radially inner opening, serves to seal off a gap present between the first valve stem and the second valve stem. An outer rim of the diaphragm is fixed in a sealing manner on the second closing body, and the inner rim of the diaphragm is fixed in a sealing manner on the first valve stem.
