Yes there's a difference. Wouldn't be wise on Honeywell's part to make 5 separate valves that are all the same.

 

Agreed. They do discontinue some and offer replacement part numbers too.

 

Why are you replacing it?

Maybe let your service provider get the correct valve and find the cause of its failure!

 

There are 4 units. All the same age. One needed to be replaced last year. I bought an extra to have on hand. My service provider just used it to replace one for a job of his own. I want to replace it and I'm being told that any VR8200C will work so I'm curious to know the (subtle?) differences in the valves before I buy it.

 

Subtle variations could be inlet/outlet size, flange/no flange, The C in your model# denotes the valve is step opening and the step settings could be different than your original valve. The OEM could have requested a special difference for their particular application.
