No, there is no valve in your car. The likely problem is a clogged core. Would you like instructions for replacing it?
I fixed that same problem in my 01 Taurus. You don't need to replace the core.
The problem is that sediment in your coolant has clogged the inlet of the heater core. Every time you run the car, the flow of the coolant packs it in tighter. I will show you how to run water thru the core and dislodge the clog.
You will only need a garden hose, visegrips, pliers and 20 minutes labor. You'll spill a few cup of coolant so figure out how to catch it and dispose of it.

1. Remove that clamp and hose (small spillage will occur).
2. Look at picture #3 at above link.
3. Use vise grip to pinch the Heater Bypass Hose. Don't crush it; just cause some restriction..
4. Remove hose on the left of the picture. Pull hose off of connector pipe.. Connect garden hose to connector pipe in place of that hose (duct tape if you have to)
5. Run garden hose at 1/2 force for 1/2 minute. This will push water thru the heater core and out the hose remove in Step 1. You will see sedimentcome out in the water.
6. Remove garden hose and reconnect everything. You should have heat now.
I wrote the procedue above and have since improved it. It will fix your heat problem.
Here is the improvement: instead of attaching the garden hose in step 4, attach the garden hose to the heater return line hose removed in step 1. This will run water thru your heater core in the reverse direction. I connected the garden hose before clamping the bypass hose and when I clamped the bypass , I saw a glob of black gunk come out. That was the blockage that prevent coolant from running thru my heater core. After putting everything back, I have more heat than I need.
Could you post the pictures again. I can't seem to get the link to open up the pictures. thanks.

There is no valve in the system ,IT sounds very possible that your thermostat may have been your problem,but now you have air in the system Taurus can be very hard to get all the air out of the system without a cooling system vac tool , first off if you hold the rpm's of the engine at 1500 rpm;s or higher do you get any heat at all coming out of the heat vents ? in the past if I have not had a cooling system vac ,I have (when the coolant was cool ) remove the heater hose in the top of the intake manifold near the thermostat ,while the engine is running (with coolant level full) and run engine until you get a solid flow of coolant out of the heater hose. then recheck you heater performance. these car have had problems with the blend door and blend door motors, but that will not cause a major heat difference between heater hoses , if you have one hose hot and the other hose cool you have got to have a cirulation problem, or air in the system
