Abstract:
1. A shut-off fitting, comprising: a housing connected to an adjacent pipeline in a pressure tight manner, wherein a diameter of the pipeline defines a tubular passage in the housing; two closing bodies movable between an open position and a closed position, wherein each of the closing bodies has a contour which, in the open position, generates a cleanable smooth pipe floor and which, in the closed position, is located on the tubular passage in a radially sealing manner, and wherein each of the closing bodies has a U-shaped profile; an articulated mechanism for moving the two closing bodies; and an actuator for moving the articulated mechanism, the actuator being vertically displaced in relation to a flow direction in the tubular passage and being arranged outside the tubular passage in the open position, the actuator having two mounting axes pivotally mounting the two closing bodies, respectively, to an end portion of the actuator, each of the mounting axes being a fixed pivot axis relative to the actuator and to the respectively mounted closing bodies; wherein each of the closing bodies is mounted solely by one of the two mounting axes.
