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

Pipe connector with compensator

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.

Actuator for a closing element of a valve

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 ( )
