A wellbore apparatus includes a connector sub assembly having a body, the body having a first end adapted to couple to a first perforating sub component and a second, axially opposed end adapted to couple to a second perforating sub component. The connector sub body defines a cavity proximate the second end of the connector sub body; and a flow path in fluid communication with the cavity and a location exterior to the wellbore apparatus. The apparatus includes a valve residing in the flow path and actuatable to block or allow fluid flow from the cavity, through the flow path, to the location exterior to the wellbore apparatus.
