quarter turn angle valve1/2 sweat

I have a quarter turn angle valve 1/2 sweat. I am going to sweat it on the the 1/2 copper to connect the toilet.
Can someone confirm the steps:
1. Cut off exsiting rusted valve off 1/2 copper
2. Sand copper nub coming off wall
3. Attach vlalve on copper with flux
4. Heat both up and apply solder.

Heating the valve, with that screw it up at all? Just kind of stay away from the handle?

Let me know if I am missing anything. Obviously a rookie.

That procedure sounds basically right to me (except you just need to heat up the cup of the valve and the solder will be sucked in) but most of the pros seem to recommend a compression valve for supply stops so you don't have that overheating problem.

I do have a compression valve as well, I bought both. The compression one is fine is it?

So I could use either, is one better then the other?

Compression is fine, put a couple drops of oil on the threads before you tighten.

>>> is one better then the other? <<<

If I answered that we would be here ages debating it over and over.

That is fine, as long as compression will work, that is easier for me anyway.

Thanks.

The compression is easier to install and replace (you'll need a sleeve puller). Most plumbers have one and it's a fast and easy job for them. Performance is the same for both so it's just a matter of ease of installation and removal.The solder has a potential to start a fire and or ruin your new valve if it's not heated properly.
