CE-DUAL-DROP-BALL-RUPTURE-PLUG-CIRCULATION-VALVE

CE Dual Drop Ball Rupture Plug Circulation Valve

The CE CV Dual Action combines the drop ball and the rupture plug circulation features into one tool. It allows the circulation of fluid through the CT tool under any normal operating conditions. By increasing CT pressure to a predetermined value, the rupture plug will blow out, thereby opening a flow path from the tool string to the wellbore, below the drop ball sleeve position. This action leaves the tool string I.D. clear for a drop ball to seat on the main circulation valve, in order to achieve the full circulation from the CT tool string to the well through the flow ports.
