ABSTRACT:
A positioning tool for use in placing a valve or removing a valve selectively from a mandrel in a tubing string includes an elongated cylindrical body member with an elongated plunger telescopically and nonrotatably arranged therein. Spring means abuts spaced shoulder means on the body member and elongated plunger to tend to urge the plunger and body member into abutting relationship adjacent their upper ends. A guide key is pivotally mounted on the body member by a shear pin and projects outwardly of a slot in the body member so that it may be engaged with a shoulder of an orientation sleeve mounted in the tubing string to align the positioning tool relative to a desired mandrel for placing a valve therein or removing a valve therefrom. A shifting tool is pivotally supported by the plunger and adapted to support a valve to be positioned in the mandrel and cooperating means on the plunger and shifting tool retain the plunger and shifting tool axially aligned in the main bore but is operable on movement of the plunger relative to the body member for shifting the shifting tool means into the mandrel for positioning the valve therein. After the valve has been positioned in the mandrel the positioning tool may be realigned axially in the tubing string to enable it to be more readily withdrawn from the tubing.
