in Gas Heating

I have an old boiler with a two stage gas valve. (Low and high)

It is a chain configuration

There is a sensor in the boiler that drops it to low fire whe set point is reached.

If I could find a used one I need a small plunger membrain part for the high fire plunger.

Any help would be appreciated.

    Can you post a few pictures of the gas valve and the part needed.

    A photo and the part number of the valve or the model number of the heater please. I have found that most gas valves are not field repairable. The manufacturer does not recommend disassembly of gas valves. You may be better off with a replacement that works in a similar way, can be set to the same specifications and has not been taken apart.

    As a Professional that likes to tinker and take things apart to see how they work, I have never in my 40+ years of hands on repair work, taken a gas valve apart and replaced any internal part, then put it back in service in someones home. I just don't want that kind of liability.

    After you make that expensive repair and you still have the same problem, What will you check next?

    What I need is the plunger nut and diaphram for the right hand side. It looks like the one on the left but is a different configuration for valve movement.

    Is that a bellows type timer? Not that i have any idea where you get one, just trying to clarify what we're looking at. The fact that Tim didn't know what it was from the description isn't a great sign.

    Bastian Morley manufactured boilers located in LaPorte Indiana, in the 1930s and 1940s. I don't think that they made their own gas valves, but they may have. Most foundries that make cast iron for boiler sections usually purchased gas valves and controls from another company that specialized in controls.

    As a result of your particular control being obsolete, you may want to consider purchasing a replacement White Rogers, Honeywell, Resideo, Robertshaw, or other currently manufactured replacement with similar specifications to solve your problem.  You need to know what gas you are using, Natural or LP.  You also need the total BTU input for your Bastian Marley Boiler and the control voltage 120 volt, 24 volt, or 250 - 750 millivolt.  With that information you may choose a valve that has a capacity the is equal to or exceeds the rating of the boiler and the correct gas and electrical specifiactions

    I might suggest one of these:

    1. Honeywell VR8300C 4506 24 volt convertible to LP or Natural gas
    2. White Rodgers 36H33 24 volt Slow opening Natural
    3. Robertshaw 700-506 Millivolt Natural

    If you have trouble selecting the proper gas valve replacement, you can post your boiler specifications here and we can help.

    In any case DO NOT REPAIR A GAS VALVE. Always replace the entire valve for safety reasons.

    EDIT:

    Some older gas valves did not include the redundant valve feature with automatic pilot shutdown.  Those valves are no longer available.  If you have a Penn Baso pilot safety switch, then it is easy to redesign the pilot thermocouple to the new redundant valve currently available.  If your pilot does not have a safety switch with a thermocouple, you may need to replace the pilot burner with a new burner that has a thermocouple component built into the bracket.

    If you have not figured it out by now, that part yot are looking for will be nearly impossible to find.

    Is there any chance that we might know the size of the boiler? perhaps a closeup of the boiler rating plate the will tell us the model number of the boiler, the BTU input, the I=B=R Net, and some other information.

    Does the pilot gas stay on all the time, even if the pilot flame blows out?

    What size is the gas pipe that is threaded into the gas valve?

    Can you also take a picture from farther back from the gas valve?

    If possible, can you take a picture that is more clear, in focus, and without shaking the camera?

    The photo you posted is impossible to see the other components that make the system operate safely.
