Abstract:
A downhole valve for fluid energized packers includes a valve sub and a packer. The valve sub further includes a control tube and a rotatable ball, the control tube having at least one closable aperture fluidly coupled to the packer when open, and the rotatable ball rotatable about an axle having at least one flow path closable by a rotation of the ball. The rotatable ball rotates about an axle coupled to a shift sleeve coupled to the lower end of the control tube. The rotatable ball includes a rotation pin extending from its outer surface and a rotation pin sleeve is adapted to rotate the ball in response to a movement of the ball toward or away from the rotation pin sleeve.
