In a locking-type gas valve having a plug rotatable by a stem having a portion which is pushed axially inwardly against a spring bias to disengage a projection thereon from a locking recess in a cap on the valve body, improved structure wherein the cap comprises a single flat plate having a slot therethrough forming the locking recess, the slot being adjacent a screw which secures the cap on the valve body and the screw having a washer which overlies the slot and retains the projection within the cap against the spring bias acting on the stem.

Locking-type gas valve

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.
