Abstract
A slam-shut safety device includes a valve body, a valve disc, a reset pin, and a guide collar. The valve disc is disposed within the valve body and shiftable along a slam-shut axis between an open position and a closed second position. The reset pin is operatively coupled to the valve disc and shiftable along the slam-shut axis relative to the valve body 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 extending away from the valve disc at least partly over the reset pin and being slidably disposed in a guide bore of a slam shut body that is connected to the valve body and supporting the reset pin, thereby providing added structural integrity to the rest pin and valve disc.
