Landon Kingsway Free Fall Fire Valve Tilt Switches are designed to be used in conjunction with our Free-Fall Valves / drop weight valves, they provide indication of valve position. Typically, they are used on generator feed or return lines. The valve will isolate the fuel in the event of a fire occurring, when the room reaches a certain temperature, it will melt the fusible link connected to the valve and isolate the fuel. The tilt switch can be mounted to the valve arm to notify the generator to shut down in the event of a fire. FEL 20-150/M 20-151/M
