This patent describes a fuel control valve construction comprising a housing means having an inlet means adapted to be interconnected to a fuel source and a main outlet means adapted to be interconnected to a main burner means. The housing means has pilot outlet means adapted to be interconnected to a pilot burner means for the main burner means, the housing means having a pilot valve seat and a main valve seat for interconnecting the inlet means respectively with the pilot outlet means and the main outlet means. The housing means has a movable pilot valve member for opening and closing the pilot valve seat and a movable main valve member for opening and closing the main valve seat, the housing means having a manually operable actuator means for controlling the operating positions of the valve members, the actuator means having an off position wherein both of the valve members are in a closed position thereof and an ''on'' position wherein both of the valve members are in an open condition thereof. The actuator means has a ''pilot'' position wherein the pilot valve member is in an open condition and the main valve member is closed. The improvement is that the housing means has a slot means therein and the actuator comprises an arm mounted to the housing means and so as to have a portion thereof disposed in the slot means, the arm being generally movable in a straight line manner between the off position and the pilot position whereby the slot means guides the substantially straight line pivoting movement of the arm, the actuator means having the off position located intermediate the off position and the pilot position.
