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.

A modular stop is provided for ball valves, such as those used as drill stem safety valves. The modular stop can be a replaceable component in valves for use with stems used to rotate a ball valve in the valve's body. The modular stop can bear the wear associated with the operation of ball valves and when the modular stop has exceeded its usable service life, it can be replaced without replacing the whole of the valve body. The modular stop can be used in new valve manufacture as well as in the retrofitting or remanufacturing of existing valves.
