Abstract
A bearing mounted ball valve () comprises a housing () having a throughbore and a valve seat () and an apertured ball () mounted within the housing in continuous engagement with the valve seat. The apertured ball is rotatable by rotation means (), about an axis of rotation, between a throughbore open position and a throughbore closed position. The bearing mounted ball valve further comprises bearing means () coupled between the apertured ball and the housing for constraining the rotation of the apertured ball about the axis of rotation between the throughbore open and the throughbore closed position. In the throughbore closed position, the bearing means is adapted to release the apertured ball from the axis of rotation to permit the apertured ball to float into a sealing engagement with the valve seat.
