I read one of the Q & A's about a gas valve for an Empire direct vent wall furnace, model #DV-215-7SG-LPG. So far I've been able to determine that it's the solenoid that's bad, anyhow,I've replaced it with a new valve and I've been serarching desperately to find another replacement valve for 2 other wall furnaces that are exactly the same model. Hopefully something cheeper than $ 129.00.
Can you help me?

Check this. You might be able to get this person to strip the parts.
