pressure balanced lavatory faucet?
The city building inspector paid a visit to the day care center I send my kids to and the director asked me for some help. On the inspector’s report, he wrote “install anti-scald mixing valves on lavs.” I did some research on the web, but couldn’t find sink pressure balanced valves, only shower. Do these exist?

He didn't say pressure balanced, but rather anti-scald.
Doing a google on that go this hit.

The first two are thermostatic mixing valve.
The last on is a pressure compensating valve.
I have not read the fine print, but all 3 appear to be devices that you install to feed standard supply valves.
