Abstract:
1. A downhole tool, comprising: a housing that comprises one or more ports that define a fluid pathway between a bore that extends through at least a portion of the housing and an annulus of a wellbore; a valve assembly that comprises a body and one or more apertures that define a fluid pathway between a throughbore of the body and the one or more ports, the body moveable between a first position that aligns the one or more apertures and the one or more ports to permit fluid communication between the bore and the annulus and a second position that misaligns the one or more apertures and the one or more ports to prevent fluid communication between the bore and the annulus; a drive assembly operatively coupled to the valve assembly and configured to move the body between the first and second positions; and a seal assembly positioned adjacent the one or more ports and comprising a seal member that forms a metal-to-metal seal between the one or more ports and the body when the body is in the second position to prevent fluid communication between the bore and the annulus, the seal member radially moveable relative to the body.
