ABSTRACT:
A valve wrench comprising a telescoping shaft assembly further comprising an inner shaft and an outer shaft, a handle pivotally attached to a first end of the shaft assembly, and a work coupling element fixed or mounted on a second end. The inner shaft may include a spring loaded button that engages the outer shaft to hold the inner and outer shaft in an operation position or alternatively in a storage position. The handle pivots to form a compact linear assembly in a storage configuration and is shaped conformal to the telescoping shaft to minimize occupied space in the storage configuration. The inner and outer shafts may be constructed from a number of complementary cross section shapes including rectangular, hexagonal, and spline to assist in the transfer of torque from the handle to the valve. A number of alternative valve coupling elements are provided for different valves.
