An electronically modulating gas valve comprising a modulating solenoid for simultaneously displacing two servo regulator diaphragms, one for controlling LP Gas outlet pressure and another for controlling Natural Gas outlet pressure. A switch is used to select operation with either Natural or LP Gas
An electronically modulating gas valve comprising a modulating solenoid for simultaneously displacing two servo regulator diaphragms, one for controlling LP Gas outlet pressure and another for controlling Natural Gas outlet pressure. A switch is used to select operation with either Natural or LP Gas, wherein the switch activates a gas selection solenoid for controlling gas flow through the Natural Gas servo regulator and the LP Gas servo regulator. The servo regulators are factory adjusted for a maximum Natural Gas pressure setting and a maximum LP Gas pressure setting. Thus, the gas valve is convertible from Natural Gas to LP Gas without re-adjustment.
