 I dont want to overstate the obvious; however, I have not read anywhere in this thread that continuity of the valve coil windings was checked and verified.  I have never worked on one of these; but, it sounds like a 2 stage gas valve. 

Can you take 24 VAC straight from the transformer and put it directly to the gas valve and verify that is changes state - ie do you hear the click or the sound of gas through the orifice.  Use a fused jumper wire and identify which wire is the common (from the diagram) so you don't ground anything out in case you are wrong.

If you have continuity and have 24 VAC directly to the valve, you may have a stuck valve.  As funny as it sounds, a good smack of the Channel Locks can help free the valve if it is in fact stuck.

This will tell you definitively if it is the valve or the board and you can move on from there.

Let us know.
