Downhole tools, system and methods of using

A downhole tool having an interior flowpath and an exterior, the downhole tool comprising:

• a first tubular member;
• a first at least one port through the first tubular member connecting the interior flowpath with the exterior;
• a shifting sleeve having a first end and a second end, the shifting sleeve positioned adjacent to the first tubular member and preventing fluid communication through the first at least one port from the interior flowpath to the exterior of the tool;
• and
• a fluid control device;
• wherein, the first end and the second end are in fluid isolation from the interior flowpath, the exterior, and each other;
• actuation of the fluid control device permits fluid communication between the interior flowpath and the first end, allowing fluid pressure from the interior flowpath to apply force for moving the shifting sleeve relative to the first at least one port;
• and
• movement of the shifting sleeve permits fluid communication between the interior flowpath and the exterior through the first at least one port.
