I don't have specific Damon info for you, BUT...
If the valve is operated by vacuum hose please check the hose before you replace the valve. On my last Ford I had a problem where the heat would not shut down fully and I swapped the valve with no change in operation. The problem proved to be a leaking vacuum hose - the portion of the hose that was visible by the valve was good but overall the hose was old, and getting rotten. The final solution was spending a day replacing every vacuum hose in the vehicle.
Now if it's a mechanical operated valve then you have a whole different issue. Just make sure that the mechanical linkage is not binding somewhere (like it is on my 1986 Fleetwood Southwind - built on a Chevrolet P30 chassis). That valve is not opening fully due to a binding flex cable. I'm going to have to replace the cable, but there are higher priority issues first.
And you still might end up replacing the valve.
