A technique facilitates performance of a gravel packing operation and desired zonal isolation. An apparatus, e.g. a sliding sleeve shunt tube isolation valve, may be deployed downhole and configured to facilitate a gravel packing operation and zonal isolation. By way of example, the apparatus contains a conduit which in an open position allows the flow of gravel pack slurry and in a closed position creates a barrier. In the closed position, upper and lower portions of the conduit are isolated from one another. When the apparatus is coupled with a packer and sand screens, the apparatus serves to create complete zonal isolation in, for example, an open hole alternate path system.
