Claim 0:
1. A valve assembly for controlling fluid communication along a wellbore tubular, the valve assembly comprising:
a ball having a fluid passage and rotationally coupled to a ball support, wherein the ball is configured to be in an open position, a shear position, or a closed position;
a main piston sealingly coupled to an activation chamber configured to contain a gas charge;
a control piston sealingly coupled to a control chamber and configured to axially translate the ball support to move the ball to the open position, in response to a volume of fluid being delivered through a conduit;
one or more push rods sealingly coupled to a corresponding rod port within the main piston, wherein the one or more push rods are configured to bias the ball support to move the ball to the closed position via the gas charge; and
one or more ball seals configured to sealingly engage an outer surface of the ball, and isolate a first wellbore environment above the ball from a second wellbore environment below the ball when the ball is in the closed position,
wherein the ball support is configured to linearly translate to contact the main piston.
