The InsertValve™ from Team Industrial Services provides "valve control today and pipe replacement tomorrow." Therefore, an 8" valve can be installed on an existing 6" pipe, resulting in immediate valve control. If the long-term plan is to increase the pipe to 8", there is no logic in installing a 6" valve on a line that is to be abandoned. The insertable valves offer mechanical joint connections, allowing for downstream pipe removal and replacement.
