Sweating on ball valves

[ss3964spd]

Searched but nothing was popping up..

Am doing a to the stud bathroom remodel and need to rough in for the new Grohe shower valve. I'm slow, methodical, so would like to first install some full port ball valves to keep "water off" down time to a minimum.

Any worries about damaging the seals? Should they be disassembled first?

You just need to have the ball valve open when soldering it on, nothing more.

Keep the heat off the middle of the valve and pull the handle from getting the rubber discolored.
