Abstract
A slam-shut safety device includes a valve body, a valve disc, a reset pin, a and a guide collar. The valve disc is shiftable between an open position spaced away from a valve seat, and a closed position seated against the valve seat. The reset pin operatively is coupled to the valve disc and shiftable between an untripped position placing the valve disc in the open position and a tripped position placing the valve disc in the closed position. The guide collar includes a hollow cylindrical portion slidably supported in a guide bore and extending at least partly over the reset pin at a location adjacent to the valve disc. The guide collar is shiftable between a retracted position and an extended position relative to the guide bore for providing added structural integrity and protecting the reset pin from bending forces.
