Abstract
A valve device selectively communicates annulus pressure or pressure from a hydraulic circuit to an actuation piston of a borehole tool to directly or indirectly set the borehole tool. A valve member is held against spring bias by a retainer whose physical properties can be remotely changed to release the force of the bias to move the valve member which in turn moves an actuating piston to set the borehole tool. The compressive strength of the material can be impacted by electric current that directly or indirectly such as with the generation of heat results in weakening the retainer. The retainer material may be surrounded with a sleeve to enhance compressive strength until the remote signal is applied such as with wireline or electric line. Other property changes to the retainer are contemplated such as volume change, shape change, change in state or change in tensile or compressive strength.
