Mixing valve for spigot

[MikefromPa]

Hello.
I would like the ability to have hot water for rare cold weather rinsing/washing. I had two ideas, the use of ball valves or a mixing valve, and after several searches with various terms, the closest thread I could find was this one:

Warm water outdoor faucet.

I'm installing an outdoor faucet that I will use for showing and dog-washing. While it would be nice to be able to control hot/cold from outside, I couldn't find any HOT / COLD faucet options that also did auto-draining (even w/ hose attached), so I've settled on just using a single-knob...

I was looking at a low cost mixing valve, as I don't need precision temperature control. My concern with almost all of the mixing valves are the minimum temps listed on their specs. 70-85 degrees. I would only use warm water a few times during cold (PA) weather, where I need to rinse off construction dirt from a vehicle, clothing, tools, etc.

Questions on this method:
1. Can a mixing valve be operated with the hot water shut off and just let the cold water pass through? I asked that question to one supplier and they said they don't know.
2. I wondered this before and this was mentioned in the above posted thread, will mixing valves (3/4") will provide proper flow rate for hose usage?
3. The distance the mixed line (PEX) will run from valve to spigot is approximately 27-30'. Is this an issue or does the mixing valve need to be installed closer to the spigot?

The other method was the use of ball valves and check valves.

I appreciate any suggestions or clarifications.

you need to decide your gpm need. most shower mixing valves are legally-required pressure balancing valves and if you close off the cold supply (like with a lever handle shut-off) it will not work.
i think perhaps you might go with an ext. mixing valve that's frost proof

As Breplum suggests a mixing hose bib is the best solution.

Thank you. I was trying to avoid that style of valve. I did see the vertical model available by Woodford but I already have the spigot on order. My previous Woodford lasted about 15 years before I forgot to close it for the winter and split..my fault. So I am replacing that one and adding one just for mixed water. Thank you for the info about the pressure balancing. That was the type of info I was looking for that I couldn't find. Using that info, leaning towards the mixing valve with 80 degree water. This line would be softened so I could just use the unconditioned line for warm weather washing and just use the mixed conditioned water at 80 for rinsing, and winter use if the flow rate of the valve is appropriate.
Thank you for the guidance
