ABSTRACT:
The invention relates to a shut-off fitting comprising a housing which is connected to an adjacent pipeline in a pressure tight manner, the diameter of said pipeline defining a tubular passage in the housing. Said fitting also comprises at least one closing body which can be displaced between an open position and a closed position. The inventive shut-off fitting is characterized in that the at least one closing body can be displaced by an articulated mechanism, by means of an actuator which can be vertically displaced in relation to the flow direction, in such a way that it is arranged outside the tubular passage in its open position. The closing body has a contour which is adapted to the contour of the tubular passage, in the open position, and is located on the tubular passage in a radially sealing manner.
