A technique facilitates utilization of a packer (34) in a borehole (32) or within other tubular structures. The packer may be constructed for mounting about a generally tubular base pipe (36). The packer generally comprises a metal sleeve (40) combined with extremities (44) located at each axial end of the metal sleeve. The metal sleeve (40) maintains a seal once expanded to a surrounding wellbore wall, e.g. a casing wall. For example, the metal sleeve (40) may be combined with an elastomer along its exterior, the elastomer sealing against the surrounding wellbore wall when the metal sleeve is radially expanded. Additionally, a device, e.g. a valve (62), is employed to control the pressures acting on the metal sleeve. For example, the device may be in the form of a valve operable (62) to control pressures acting on the metal sleeve (40) while miming-in-hole, during expansion of the metal sleeve, and after setting of the packer.
