Analog Water Valve 1/2" or 3/4" Answered

Hey guys, new here. Been looking around for parts for my project for a while now and so far have come up pretty empty handed. I am looking for some parts, or even some information on if anyone has a specific place for parts when it comes to household plumbing.

i am trying to source out Variable water valves of the analog variety in 1/2" or 3/4" inlets (preferably in brass) to be controlled by an Arduino. They need to be able to handle a PSI range of 80-100psi and in a N/C state. $0-$30/each preferably

Without fully giving away my project idea I basically am looking to switch out manual hot/cold water taps with electronically controlled ones. I need to be able to adjust how open the valves are so I can vary the temperature between the two pipes so that I can get an Arduino to control (with other sensors) and get a water temperature out the drain that is equivalent to bath water. (Hence why I need them to be variable and not just on/off)

I have have checked local shops, asked plumbing friends, alibaba, and (of course) Google. And I just can't seem to be able to punch in the proper keywords to find exactly what I am looking for. The closest thing I can find is automatic sink tap solenoids but they require a manual set up and only output at that mix ratio, So I'm hoping that someone has a plumbing supplier to direct me to, I'm pretty much out of ideas.

thanks in advance!

electronic mix or mixing valves.

Used for showers, heating systems, etc. you may be able to use the one out of a washing machine. Good luck.

If you can't get motorised valves, why not motorise some valves?

You could connect a suitable motor to the shaft of a gate valve, or a servo to turn the arm of a lever tap.
