Installing additional natural gas valve to main branch/ any issues?

[Mikepier]

I am getting ready to install an additional gas line outside my house for my grill, and in order to do this I have to shut off the main at the meter. I have done this in the past for other work and have found it to be inconvenient because I always have to re-lite the pilot on the water heater.
To avoid this in the future, I want to install an intermediate shut off valve on my 3/4" line ( after the furnace and water heater, but before my gas dryer, stove, and grill) so I can still do work adding any future branch lines without having to shut off at the meter.

Any issues doing this? My concern was if adding a valve would cause the gas flow to be restricted to the dryer, stove, and grill . I was told to get a "full port" gas valve.
Also is it common to add intermediate valves on the main branch line?

I don't see any problem with adding valves as you see fit to segment
it the way you want. I don't think you need anything special,
just a ball valve rated for gas, which isn't going to have any
significant effect on cutting down the flow.

Are you allowed to use regular ball valves for gas? I saw them in Lowes and HD and it says rated for Water, Oil and Gas, but I thought you could only use a dedicated gas valve for gas.

Check your local code. They are allowed in at least some locations.

The gas also refers to other gasses. In industrial applications you can
find nitrogen, oxygen, argon, etc., often at high pressures.

Sounds like a huge amount of problem for a non-problem. Lighting a pilot light?
That's a 2 minute job at best. How many times are you going to add to your gas
piping?

When I re-plumbed the piping for my water heater, I added a plugged "T" where
the pipe turned so I could add a gas stove later without having to change any of
the current pipes. For me, worrying about a pilot light never entered my mind.

Do what you want, but if you ask me, it would be easier to light the
pilot once every few years than install the valve.....

I guess that depends on what you mean by "regular ball valve". If it
says it's rated for gas, then I'd say that means it's rated for gas.
I see new installs of gas here that passes code and the valves
look just like ones they sell in HD. It would be pretty irresponsible
to be selling valves labeled for gas at HD that aren't suitable for
NG. They are selling the pipe, WH, appliances, etc. that people are
using with gas.
