A ball valve () has a blocking element () movably guided in a fluid passage of a valve housing () and movable by an actuating device () from a pass-through position connecting at least two connecting points () to one another in the valve housing () into a blocking position interrupting this connection, and vice versa. A sealing device has at least one sealing ring which, together with its central opening, comprises the fluid passage () and seals the fluid passage along at least one sealing gap. The ring profile of the sealing ring has a ring opening that interrupts this profile such that the sealing ring changes from an initial shape to an installation and different shape that seals the sealing gap with a predefinable pretension having an increased sealing force effect.

Valve device, use of such a valve device and associated sealing device

An apparatus for routing cables in wind turbines has a plurality of bushings () for cables distributed on at least one base body () that has a preferably round contour. The bushings () are provided with a guiding arrangement () permitting the cables to move relative to the part of the bushing () that surrounds the guiding arrangement.

A clamp for securing components, in particular string-like or linear structural members, like pipelines, hoses, or cables, has at least one clamp part (). The clamp part outer contour () delimits at least partially a receiving space () for receiving the component. The one clamp part () has a mechanism () for minimizing corrosion, in particular, crevice corrosion, at every component that is held. The mechanism has at least one sacrificial element () that is visibly consumed with the onset of corrosion and continued duration of use of the clamp fastener. The respective sacrificial element () is placed, as an independent component, on the outer contour () of the clamp part ().

Clamp for securing components

A ball valve has a valve housing () receiving ball spindle () pivoted around an axis in the housing (). A ball body () as a blocking element is between the input part and the output part of a media passage () of the housing. The flow opening () located in the ball body () is alignable with the passage () for unblocking the ball valve by turning the ball spindle (). The ball body () is supported on two identical end sections () connected to and axially spaced from the ball body (). The support on at least one end section () is a support cover () having integrated slide bearing elements () detachably mounted on the housing ().
