1. A system for use in a well, comprising:
a tubing string having a base pipe with a base pipe interior, the tubing string being disposed in a borehole such that an annulus is established between the tubing string and a surrounding wall surface; and
an expandable metal packer mounted around the base pipe, the expandable metal packer having an expandable metal sleeve mounted along the base pipe via extremities, the expandable metal packer further having a pressure control device, the pressure control device being actuatable to different flow positions via application of pressure inputs along the base pipe interior, the pressure control device comprising:
a valve held in a first flow position allowing fluid communication between the annulus and a packer interior and preventing fluid communication between the base pipe interior and the packer interior while the tubing string is run into the borehole, wherein the valve is actuatable to a second flow position, the second flow position preventing fluid communication between the annulus and the packer interior and allowing fluid communication between the base pipe interior and the packer interior to enable expansion of the expandable metal sleeve, and wherein the valve comprises:
a first piston disposed in a first passage and configured to control fluid flow between the base pipe interior and the first passage; and
a second piston disposed in a second passage and configured to control fluid flow from the base pipe interior to the packer interior through the first passage.
