Shower valves
I am looking for the name of the type of shower valves that prevent scalding in the shower when water is used in another part of the house.

Are you looking for a new anti-scald valve to replace old (find at a local plumbing supply store) or just new shower fixture with anti-scald? All single handle shower's should have an anit-scald valve for the blister box pipes behind the shower control handle. 3and 2 handled showers don't have an anti-scald and as I understand it can't be retrofit. So replacing blister box/mixer = installing single handle shower control to bring the shower up to code.

Single handle shower controls now have to use a pressure balanced design to prevent scalding. This is typically done with an internal piston assembly (mine is in the form of a replaceable cartridge) that cuts water flow in one line if pressure in the other line drops and vice versa.
