Abstract:
An apparatus, system, and method of use enable control of fluid flow in a wellbore tubular. The apparatus comprises a pusher rod with a bore for fluid flow contacting a rotatable ball with an internal bore comprising at least one pilot, wherein the seat between the pusher rod and the interior of the tubular prevents fluid flow. Pressure changes on the pusher rod rotate the bore of the ball in and out of contact with the bore of the pusher rod, to enable or prevent fluid flow, respectively. A method of use opens the ball by exerting pressure and/or force on the pusher rod to enable fluid through the ball by aligning the internal bores. Fluid flow is stopped by pressure exerted on the bottom of the ball causing the ball to rotate whereby the internal bore of the pusher rod is connected to the exterior surface of the ball.
