ABSTRACT:
A casing cementer with torque-limiting rotating positioning tool. The casing cementer comprises a housing with a rotating valve sleeve therein. A positioning tool is used to rotated the valve sleeve between open and closed positions thereof. No reciprication of the positioning tool is required. The valve sleeve has a sealing ring molded thereto for sealing between the housing and the valve sleeve. The valve sleeve preferably has an inside diameter at least as large as an inside diameter of the casing. A stop is provided to limit movement of the valve sleeve when it reaches either the open or closed position. A clutch in the positioning tool provides for torque-limitation and a ratcheting indication to the operator at the surface when the valve sleeve has been opened or closed.
