A drill stem safety valve actuator that eliminates the need for a hydraulic union. The actuator can include a mounting sleeve that can be affixed to the valve, that can further have a pinion gear that can rotate a ball valve. The actuator can include a rack sleeve slidably disposed on the mounting sleeve, having a rack configured to engage the pinion wherein sliding the rack sleeve linearly along the length of the mounting sleeve rotates the pinion, thus, the ball valve.
