Abstract: 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.

Abstract: In a double seat valve with upper and lower valve discs and a flow divider in a leakage room, wherein respectively one valve disc can be set to a lift position to supplying a cleaning medium flow into the leakage room, and first channels are provided in the flow divider and second channels in the lower valve disc towards a leakage outlet, the first channels are disposed in extensions of the flow divider that axially bridge the lower leakage room part and that join within the second channels the flow divider forming in at least one of two lift positions with its external circumference with the external wall of the leakage room a leakage gap for a side flow that is significantly smaller than a main flow that is deflected and directed by the flow divider into the first channels or into the second channels and to the leakage outlet.

Abstract: 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.
