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.

Poppet valve

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.

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.

A pipe connector including a compensator and a centering sleeve that, in the mounted state, extends along the entire length of the compensator.

A valve device includes a double-seat and/or double seal valve and a cleaning valve to clean the leakage space of the double-seat and/or double seal valve. The axis of the cleaning valve forms an angle between 1&#xb0; and 89&#xb0; with the axis of the double-seat and/or double seal valve.

Double seat valve with rinsing valve

A multi-piece valve disk of a sliding and/or seat valve, a ring seal with an elastic sealing ring with an external sealing zone is placed in a ring groove of the valve disk onto a dimensionally stable backup ring, and where an elastic restoring region effectively positioned between the backup ring and the external sealing zone is arranged in the backup ring, the restoring region being embodied in one piece with the sealing ring of its material adjacent to the external sealing zone of the sealing ring.

Multi-piece valve disk

An actuator for a rotary function element, having a housing with at least one pressure means supply and being closed at both sides by a cover, in which housing a piston is guided to reciprocate in a sealing manner, the piston containing diametrically opposed, convolution-like connecting links for a transverse axis of an actuator shaft rotatably mounted in one cover, and having two guide rods firmly anchored in the housing only at one end and engaging into guides in the piston, with the one guide rod anchored in one cover, whereas the other guide rod is anchored in the other cover, and the two guides end blind in the piston in opposite directions.

A double seat valve having a seat for cooperation with two valve disks which are linearly adjustable relative to each other and together relative with respect to the seat, for a seat valve function and a sliding valve function, each of the valve disks containing a ring seal with an elastic sealing ring in a ring groove, both sealing rings being manufactured with the same shapes and dimensions, each sealing ring being positioned in the ring groove with a backup ring, and both sealing rings being arranged in rotational positions differing with respect to the respective sealing function relative to the direction of adjustment of the valve disks.

A drive device for a double seat valve having, between flow paths, a seat and first and second valve disks, where first, second and third pistons movable in a sealed manner by alternating pressure pulses for initiating an opening cycle and cleaning cycles of the valve disks each are provided in a drive device housing, where the pistons can be selectively connected with valve disk couple elements so as to transmit movements. Pressure transmission paths lead into the drive device housing to chambers defined by the pistons, the second piston being guided in a sealed manner separate from the first piston in the drive device housing, sealing areas of the first and second pistons define a first chamber in the drive device housing, and at least one pressure transmission path leads, for the cleaning cycle of the second valve disk, laterally and transversely to the common axis of the drive device housing and the valve chamber at least directly into the first chamber.

Device for driving a double seat valve

The invention relates to an operating device for a rotatable closing element of a valve such that, a desired angle of rotation can easily be set and maintained. This is achieved in that two guide grooves ( ), which are incorporated diametrically opposite each other, are bounded on all sides by a piston shank ( ), in that their respective courses are precisely or more or less symmetrical at all points, in that in each instance the courses have, in relation to the axis of the piston ( ), a greater pitch angle in a central portion (angle b) than in their two portions on the end side (angle a) (a>b), and in that the stroke of the piston ( ) is limited on one side by application of the front-end piston shank ( ) to the cover element ( ) and on the other side by application of a piston base ( ) to a stop element ( ) which is mounted in the housing base ( ) of the housing ( )

Operating device for a rotatable closing element of a valve

The invention relates to a bellows to seal a valve rod passage in a lifting valve, specifically formed as an expansion bellows or corrugated tube, which ensures a reliable, hygienically proper and durable static sealing of the connecting flange of a closing-member unit in the box of the lifting valve under the occurring forces at an adequately long service life. This is achieved by the fact that the connecting flange (,) of the closing-member unit (,), in the region where it is connected to the bellows (,), has a fastening component (,) indirectly supported on the box side to absorb, in a way free from bending moments to a very large extent, the forces resulting from the valve-lift induced deformation of the bellows (,) and/or the respective pressure in the box (,) and is reduced, in the area of its conical sealing surface (,), to a minimal wall thickness meeting the strength-related requirements, in the form of a diaphragm-shaped sealing element (,), and that the diaphragm-shaped sealing element (,), on its side facing away from the conical scaling surface (,) has at least one biased elastic thrust ring (,) which presses the sealing surface (,) onto the complementary annular seating surface (,).
