Anthony, You may find that replacing the whole valve is a bit more complex then you think. The currently available valve that replaces yours is likely one of these:

This valve has different port locations, so some tube bending would be required. Also this valve would have an external thermostat. Most early Trilliums used a bulb style temperature sensor. What Duo-Therm
furnace is this out of?
For an upcoming thread, I have just recently dissected an RV18AA02. This is the gas valve that is in Duo-Therm models 65211-2 (early 1300) 65810-002 (Later 1300) and a 65512 (4500) furnaces.
I suspect the model number of your gas valve is ITT RV18AA06. Please see the attached pictures. If you think the diaphragm is the same, the I will send it to you, for the cost of shipping.
