Heater hose ball valve 93 D250?
I was reading the archives, and came across a thread to add a heater hose shut off valve of some sorts. I guess NAPA sells one or Home Depot. The question I have, was this a way to bypass the factory heater valve or something done in addition to aid the AC evaporator from radiant heat from heater core?

It was/is on the heater core inlet line and closes when the AC is on to stop the flow of hot water into the heater core. I could not find an OEM replacement so found one from a Ford Ranger (??...can't recall now) that fit and works properly with the vacuum signal. I also installed two manual heater hose shut off valves to totally stop all flow into the heater core.

If your vacuum valve still works but may be leaking a bit, why not put a manual valve in series. This way you still get to regulate the heat in cold months and you can shut it off completely in hot months.

Finally found my post from a couple years ago.....
Here's the set-up I put on my truck....
I searched high and low for the "right" manual shut off valves I wanted to use. Many hours were spent searching all over the internet until I happened across these babies!
4 Seasons 84706. Used on early 70's dodge pick up trucks.
And the vacuum operated shut off valve was not available for our trucks...at least with a 5/8 x 5/8 hose connections. Maybe I just couldn't find it, but I searched high and low and never could find a direct OEM style replacement.
I found many that would "work" but looked hideous, IMO, but eventually found one I liked.
4 Seasons 74859. Used mainly on Ford Rangers from 2003 to 2008.
Now here it is all installed...
Now next summer I can just turn off the valves and no heat, or coolant will enter the heater core to affect my AC temps.
