A method and device are disclosed for fitting a shaft-butterfly valve unit in a pipe formed by a butterfly valve body. The device comprises a frame receiving the pipe with its unit. It also comprises a first thruster for moving the shaft in a first direction as far as the first abutment position and a second thruster for moving the shaft in the opposite direction as far as the second abutment position. A sensor detects the abutment positions, and the gap (j) between the abutment positions is computed. The first or second motor is controlled for moving the shaft from the first or second abutment position by a distance equal to a predetermined fraction of the gap.

Method and device for fitting a rotary throttle unit in a pipe

A method is provided for fitting a butterfly valve on the slotted shaft of a carburetor body. The slot is first of all oriented parallel to the axis of the duct. Then one edge of the butterfly valve is gripped by a gripping member and is inserted as far as its final position by moving the member along the axis of the duct. The unit formed by the butterfly valve and the shaft is rotated as far as the position in which the butterfly valve closes the duct by exerting a force with the gripping member and a retaining torque with a motor.
