SLAM SHUT RESET PIN GUIDE ASSEMBLY AND SLAM SHUT SAFETY DEVICE COMPRISING SAME

摘要

A slam shut safety device includes a valve body, a valve disc, a reset pin, and a reset pin guide. 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 reset pin guide supports one end of the reset pin, thereby providing added structural integrity to the reset pin and valve disc.
