Patent ID: 7758019

Claim:
A safety valve, comprising: a first generally tubular body having a first flow path therein; a second generally tubular body having a second flow path therein axially aligned with the first flow path when the first and second bodies are mated; a body connector for axially and rotatable interconnecting the first and second bodies; a ball supported between the first and second bodies and having a flow path therein, the ball rotatable between an open position and a closed position for regulating flow between the first and second flow paths; a first seat for sealing between the first body and the ball when closed; a ball centering member for engaging the ball at a position axially opposite the first seat with respect to a center of the ball; an outer actuator sleeve positioned between the first and second bodies and having an outer surface exposed to an exterior tool and rotatable with respect to the first and second bodies; and a connecting member acting between the actuator sleeve and the ball, the connecting member moving axially in response to rotation of the outer sleeve and thereby rotating the ball between the closed position and the open position.
