Natural Gas Ball Valve?


When installing a ball valve on a residential natural gas line, is there any difference between those common NG red ball valves like this one:




Or a standard "250 or 600 WOG" valve like this one:


Is there some kind of code that dictates that the red valve must be used?

WOG = water, oil, gas
I have used the ball valves on gas multiple commercial jobs.
I can't quot a code reference though

Yes, me too.. I have no doubt they will function properly but I wasn't sure if there was some residential specific code about them.. You never know when there's some obscure code snippet like "No valve shall have a handle longer than your little finger" or something.

I know they're fine up to at least 5 PSI gas because I've installed them before at those pressures on a 5000 sqft oven.

I like the Red Handled one, due to it does not stick out if attached to the gas line behind a stove, next to a furnace or water heater. The second one is good for a shut off for a gas fired fireplace. Gives you something that you can push with your hand, or pull on it, vs. trying to turn it with limited space.

I recently installed a 1" WOG ball valve because I couldn't find a gas valve that size.
At the more common 1/2" and 3/4" pipe sizes... use the one expected to be seen.

All kidding aside, those long handles can be a safety factor when clothing unknowingly gets caught and turns the valve on. You don't want to hear the rest of the story "Paul" it wasn't all that funny. although my co-worker thought so at the time.
