Abstract
A control valve assembly for a pilotless gas burner in which the valve has a gas inlet port and a single gas outlet port. Interposed between the gas inlet port and the single gas outlet port is a sleeve that provides predetermined amounts of gas flow to the single gas output port depending upon a plurality of orifices in the sleeve being opened or closed. The valve automatically closes if the main burner flame is extinguished and must be restarted manually. Further, manual control of the valve is provided by a shaft which is rotatably and axially inserted into the valve to provide ignition fuel to the burner and to regulate the amount of fuel flow through the sleeve to the single output port and the burner.
