I have a pex 90 degree elbow with a sweated on stub out on the other end. When I put in the new sink and install the water line, is it OK to sweat on the shut-off valve to the stubout or will the heat melt the pex on the other end of the 90 degree elbow. The stubout is about 4 inches long. I could play it safe and use a compression shut off. Thanks in advance for the help!!

I wouldn't, but....
Take a wet rag and lay it over the stub as close to the wall as you can to absorb excess heat close to the plastic.
If your sweating on stops with chrome sleeves, it definitely wouldn't work.

Also, focus the torch's flame on the valve as opposed to the pipe, make sure the stops are in the semi open position...you'll melt the seals if it's closed.

Use a compresson stop and ad a little pipe dope to the compression ring
before tighten it down but not to tight.
