Looking for an Itt/General Control Valve MR4J

[Doug]

I'm looking for a type MR4J thermopilot control valve as made by ITT/General Controls.

ITT has since sold off that division and the new owner no longer makes that product line.

I was able a few years ago to buy one off of my friendly neighborhood gas company serviceman's truck. However, the local gas company and HVAC repairers are now long out of stock.

I use this in a Magee gas space heater in a small cottage. I checked with REPCO out of TX. They don't have one but MAY be able to rebuild mine. I'd still like to find a N.O.S. spare...

tnx,

Doug

or just find one with similar specifications and size:

or hd supply search catalog for "gas valve"

Honeywell 'Product Cross Reference' for an ITT/General says that a functional replacement for: MR4 is either C513B1018 or C581B1002 or C580B1012 MR4B is C580B1012 MR4FG is either C5133B or C5434B My book doesn't list the MR4J, so you should to call Honeywell and/or check the specs before installing one of these.

I've searched all of the above and much more, with no results.

Thanks, I'll check the Honeywell cross lists but in a past examination none of the above will work.

The MR4J is unique because it has a separate 3/16" gas input line dedicated to feed the pilot.

This is necessary in my application since an upstream thermostat shuts down the main gas feed to the MR4J, making a separate source for the pilot necessary.

However, in case I've misread the specs on the Honeywell substitutes, I'll check again.

Another solution would be to rework the system and use a non-safety pilot, i.e. a pilot that doesn't shut down with flame out. In reality, that's not particularly dangerous. There's very little gas flow. However, it's certainly not ideal.

I've got four older Bryant gas furnaces in my rental apartments that do exactly that...

BTW, in case some of you folks want to give me flames about "not getting a professional involved", I tried to do that. None of them have any familiarity with this older equipment and have refused to service it.

My local gas company would, but they can't get parts and are not willing to make substitutions.

I've served HVAC equipment for over 30 years and have yet to blow myself or anyone else up.

Thanks,

Doug

Hi Bob,

Thanks for the above info but after checking the current Honeywell catalog, all the above products seem to be discontinued.

------------------------------------- Hey I am in New Hampshire and there is a store that sells parts for gas and gas stoves. They sell Glenwood , Magee , Bengal and some others. Most of these parts are no longer available through the manufacturer. So it is amazing that they still have all these parts. I was in the store the other day and they had mr4 valves. They have a web site ManchesterApplianceParts.com
