Abstract
Rotatable valve plug in a gas valve has two circumferentially spaced recesses in its exterior registrable with the inlet in the valve body. Two axially spaced pairs of relatively small ports extend from the recesses to the internal gasway in the plug through which gas flows to the valve outlet. One port of each pair opens into each recess. Both recesses register with the inlet in intermediate on position of the valve, and only one recess registers with the inlet in low position. A screw threaded into a hollow operating stem on the plug is turnable to close and open selectively the inner ends of one pair of ports to convert the valve optionally for use with natural gas or LP gas.
