Ball valves vs. gas valves

Can a ball valve be used for nat gas? Would like to, cuz the orifice is
MUCH larger than a gas valve.
The HD guy said No, cuz "gas is corrosive". Heh, but it don't corrode black
pipe....

Opinions?

Yes it can, if it carries a label that says (WOG) on it

If it has a yellow knob 1/4 turn handle.

Ball valves are the only type I use for natural gas. NG suppliers treat
corrosive "sour gas" to keep it out of the domestic distribution
network. ^_^

Depends on the ball valve. If it is WOG rated, it is good for gas.
In SOME areas they need to have yellow handles for gas, in other areas
red is OK.. Here in Ontario any WOG rated valve is OK. Most are
certified for 600psi, which is EXTREME overkill.

I am assuming that you are referring to small - 1/4. 3/8. 1/2" valves
but as for the category of "ball valves" larger ones, say 2", 4", 6",
etc. are commonly used in the gas industry. In fact if memory serves
that are the valve of choice over gate valves for handling gas.

What kind of ball valve? Water shut-off valves (PVC, brass) also come
in "ball valve".

If memory serves me right, WOG means it's rated for Water, Oil and Gas
service which is what most of the ball valves I come across are. ^_^

Not overkill at all. Sure, for natural gas, but it can be used on
high pressure oxygen, nitrogen, argon, and on and on. That same valve
will find its way to industrial applications

Heh, rarely is there this much consensus on an issue.... LOL

I'll spray paint the handle yellow, jic... :)
In this case, I'm piping in my 15 kW genset, and depending on which table
you use, I am sort of squeaking by, supply-wise, so I can use every sq in of
orifice I can get. The diff between the two is quite a bit.

there's some really sketchy stuff at HD, so the droid may have been onto
something when it comes to the stuff they sell.

My favorites are the plastic stemmed water cutoff valves for sinks and
toilets that last about 3 cycles before they somehow fall apart. The brass
nuts for the compression fittings are so thin and crappy they I've seen
some just crack and spring a leak just a few years after installation.

somebody somewhere must be proud of the cost savings they came up with.

Oh, they are proud indeed. They have whole board meetings, with actuaries
and all, to figger these consumer assfuckings out.

Why? It is good for "gas" which can be something else from residential
natural gas and at much higher pressure.

Obviously - but we were talking natural gas applications. The
normal conical gas valves are only good for what? 45 psi???

Well....The Gas is not corrosive but the additive "mercaptan" is a reactive substance due to the sulphur. This is probably what he was referring to.

I used ball valves when I re-piped the gas in my house, and the inspection went
fine.
