responsive element responsive to a driver 34 the valve is preferably carried in a single housing body 31 for example as is accomplished in a sourdillon valve model 099 including a cut off valve and a flow rate adjuster the responsive element 36 in the preferred embodiment is a pick up coil 58 although other electronically driven devices could also be employed the responsive element 36 controls at least one valve actuator for example plunger shaft 38 for controlling the connection between the gas supply 20 and the gas manifold 16 in the preferred embodiment shown in fig1 the responsive member 36 includes the plunger shaft 38 acting as a valve stem that carries a valve head 40 for displacement into contact with and away from the valve seat 42 closure of the valve head 40 against the valve seat 42 obstructs the flow of gas input between the supply 20 and the gas manifold 16 in addition the valve construction shown in fig1 includes flow rate adapter that varies the amount of gas that can be passed from the supply 20 to the gas manifold 16 and into the burner 14 for example the actuator 22 may include a tapered valve stem with a flow control channel that controls the amount of blockage of the flow passageway through the valve 30 from its inlet 72 to its outlet 74 both the valve head 40 and the valve stem.
