A gas valve device includes a pressure regulator and two solenoid operated valves connected fluidically in series. The valve body therein is selectively cored and machined so as to provide a gas valve device which is compact in physical size, inexpensive to produce, and versatile in that it provides a choice of several gas outlet directions.

In a gas valve, a pressure regulator; two solenoid operated valves; a valve body comprising a casting selectively cored and machined to effect a desired gas outlet direction; said casting having a pressure regulator chamber; said casting having first and second core chambers spaced from each other and from said pressure regulator chamber; each of said first and second cored chambers having a bottom wall and a cored gas passageway extending downwardly from said bottom wall; one of said first and second cored chambers being selectively cored to provide a cored recess spaced from said cored gas passageway and extending downwardly from said bottom wall thereof; said casting having a first gas passageway selectively machined for connecting said pressure regulator chamber to the other of said first and second cored chambers not provided with said cored recess; said casting having a second gas passageway selectively machined for connecting said cored gas passageway extending downwardly from said bottom wall of said other of said first and second cored chambers to said cored recess of said one of said first and second cored chambers; said casting having a third gas passageway selectively machined for connecting said cored gas passageway extending downwardly from said bottom wall of said one of said first and second cored chambers to a gas outlet means; and said solenoid operated valves being adapted to control flow of gas out of said first and second cored chambers.
