I have a valve on a Bryant Burner for an old gas furnace. There seems to be a problem with the gas valve that feeds the burner. Are 40 year old valves available? Thank you. Dennis

Depending on the furnace, yes they are available. Many of the older gas valves can be replaced with "Generic" ones that are not too difficult to retrofit...

Rick,
Thank you for the quick reply.
I live in Montreal, and have looked around town for either a NOS or replacement, without luck. Perhaps I'm just not looking at the right places.
Would you know where I could start looking?
Thank you again.

Dennis
