Abstract
A technique facilitates actuation of a downhole device, such as an isolation valve. According to an embodiment, the downhole device may be in the form of an isolation valve member, e.g. a ball valve element, actuated between positions by a mechanical section which may comprise a shifting linkage. Actuation of the mechanical section, and thus actuation of the isolation valve member, is achieved by a trip saver section controlled according to a pressure signature which may be applied from a suitable location, e.g. from the surface. The trip saver section comprises a housing having an internal actuation piston coupled with the mechanical section. The trip saver section further comprises a pilot piston and a plurality of chambers formed in a wall of the housing and arranged to enable shifting of the actuation piston in response to a predetermined series of pressure pulses or other suitable pressure signature.
