Abstract: A slam-shut mechanism for operatively connecting a slam-shut control element of a fluid regulator with a controller for the control element. The mechanism includes a shaft and a cam carried by the shaft and having a cam surface adapted to be operatively connected to the slam-shut control element. The mechanism also includes a latching pin carried by the shaft, a latch, and a lever operably connected to the latch and adapted to be selectively engaged by the controller. When the controller engages the lever, the latch is movable from a first position, in which the latch securely retains the latching pin, such that the cam surface is arranged to retain the slam-shut control element in a fully open position, to a second position, in which the latching pin is released from the latch, thereby allowing the slam-shut control element to move from the fully open position to a closed position.
