ABSTRACT OF THE DISCLOSURE A fire control valve and more particularly a valve installed in the flow line of a flammable or other hazardous flowable material which is normally open but will be automatically closed to interrupt the flow of flammable or hazardous material to a discharge point in the event of a hazardous condition occurring. The valve is held in an open position by a fusible link which retains a spring biased pin in engagement with a spring biased valve stem to retain the valve in open position. The fusible link will melt when subjected to predetermined conditions such as a high temperature condition which occurs in the event of a fire thereby releasing the pin and valve for movement to a closed position for stopping flow of flammable material in order to control the fire or other hazardous condition.
