Hi All,
I've replaced several valves (standard shutoff) over the years, the ones you
turn several times, to open/close. There may be proper name for them, but I
do not know.
It seems to be hit/miss proposition for me. Some of them leak at the shaft,
after installing.
I suspect the reason is that the rubber gasket gets cooked during the
heating process. Many valves have a rubber parts in two places, one where
they close the flow and another around the shaft.
How do you guys manage to get the valve installed without overheating the
rubber parts inside? Any tricks?
Regards,
RichK

Remove the stem and handle before you apply the heat and replace them =
after the faucet cools down.

What works for me:
1. Disassemble valve as possible first.
2. Heat area to be sweated as intensely and for as little time as
possible.
Usual picky stuff about cleaning, fluxing, etc.

remove the handle stem then sweat. then reinstall after its cool, this
mahes it easier to get it hot enough, so bbetter seal.
be certain to clean all parts, flux all parts. then heat the part not
the solder. heating the valve body rather than the pipe helps suck the
soder into the joint

They are called gate valves. Like the other said - remove the stem before
applying heat
