An isolation valve system includes a well string having an isolation valve including a ball rotatably mounted to a pair of inserts for rotation about a fixed axis, an arm coupled to the ball at a position offset from the fixed axis, and a mandrel connected to an actuation end of the arm, the mandrel and the actuation end of the arm being disposed uphole of the ball. Via the actuation end of the arm, the mandrel forces rotation of the ball from a closed position to an open position by moving in a linear direction away from the ball, which allows flow of fluid along a through hole of the ball.
