ABSTRACT:
A structural kit for the installation of a flow regulator valve in pipeline without interruption of the fluid flow in the pipeline. To make precise cutting of the desired portion of the pipeline in simple cutting operation and to just fit the valve into the cut-away portion thereof, a plane of the ring-shaped gear having cutting tools is tilted against a plane perpendicular to the axis of the pipe so as to cut away the pipe section the upper portion of which is longer than that of the bottom portion thereof.
