LINER HANGER EXPANSION TOOL WITH ROTATING BALL VALVE

A rotating ball valve may be employed in a liner hanger setting tool. A rotating ball member maintains contact with a valve seat throughout the operation of the rotating ball valve, thereby preventing debris from settling on the valve seat and compromising the integrity of a seal through a fluid flow path defined through the setting tool. The rotating ball valve may be actuated by selectively applying fluid pressure to the flow path, or by mechanical manipulation. Once the fluid flow path is closed, a latch may be activated to maintain the rotating ball valve in the closed configuration and a pressure may be applied against the closed rotating ball member. A downhole movement be induced by the applied pressure to drive an expansion cone through an expandable liner hanger, to secure a liner in the wellbore.
