Abstract
The disclosure relates to a valve seat driven forced seal ball valve including a valve body, a first seat, a ball and a stem. The stem drives the ball to rotate between an open and a closed positions. The stem also drives the first seat towards and away from the ball. When the ball is in closed position, the first seat presses against the ball to achieve a forced seal. The first seat is driven towards and away from the ball by a first seat drive ring. The first seat drive ring is provided with female threads and the first seat is provided with male threads. The first drive ring drives the first seat towards and away from the ball by a screw connection.
