Abstract
A differential pressure operated blanking tool includes a Y-tool having first and second limbs connected together via a throat. A ball valve is selectively positionable to close one or other limb of the Y-tube against fluid flow. A housing has an opening in one side thereof of a size sufficient to allow the hall to pass through, and an actuator mounted on the second limb and in the housing wherein fluid flow within the tool carries the ball valve through the opening in the housing to a position where the second limb is closed against bias of the actuator. When the fluid flow is removed, the actuator operates to force the ball valve out of engagement with the second limb whereupon the ball passes through the opening in the housing towards the first limb.
