Gas Valve

bobb12345

I have a Crane Natural Gas Boiler No. 4-8 which  I've found is also called  a Sunny Day 8 Series , I need a Gas Valve for. It looks like it's a 24 volt but most of the identifying information on the Gas Valve itself has been worn away and illegible.

Larry Weingarten

Hi, If you have an independent appliance parts supplier in your area, I'd take a bunch of photos of the valve and any data, like operating voltage and pipe sizes, and see if they can help identify the valve and find you a replacement.

Yours, Larry

Why do you think you need a gas valve? Is it standing pilot?

Tim McElwain

Give me a picture and I will identify it for you.

Because the gas supplying the boiler doesn't shutoff, after the thermostat calls for it to shutoff, the boiler had to be turned off by cutting the supply.

@Tim McElwain will probably need more information,

1. Is the boiler natural gas or propane
2. pipe size into valve and out of valve
3. BTU rating if you know

Mabe you can take a few pictures from a couple of steps away different angles

This is what I have, it's a natural gas boiler

This is where the gas valve connects

Not sure what size pipes they are, it uses this pump if that helps at all.

Gross leakage from or onto gas piping. Lack of maintenance?

Definitely lack of maintenance, this boiler was on the house when I moved in...

You need a good tech to replace that. it can be replaced with a modern combination valve by someone that knows what they are doing. It would replace the regulator and valve.

The guy who said it needs a new valve is like the only one I trust in the area. He said the supplier he uses knows what boiler this is but they don't have a replacement valve. I was hoping someone would know what valve goes with the boiler.

@bobb12345

The boiler is old you probably can't get the exact replacement valve any more. But you can get a valve installed that will work

find out who they call when they're stumped. It isn't just parts swapping, you need someone that really understands how to set up a gas burner. You will replace the valve and regulator with a modern combination standing pilot valve, hook the thermocouple and pilot up to the new valve and check/adjust the pressure, combustion, and draft with the new valve.

Is that water on the regulator or is the circulator above it and someone got a little overzealous with the oil?

Tim McElwain

What is the voltage to that valve and does it have aa pilot which operates with a thermocouple?

Looks like 24 V and yes it has a pilot and a thermocouple 

EdTheHeaterMan

@bobb12345 I can't be sure but if I was at your home on a service call and your pilot end of the thermocouple looked like this and the other end looks like this
Then I would have this valve on my service truck.
and you would have heat tonight.

If you had a thermocouple that looked like this
then i would have this valve on my truck
and you would have heat tonight.

But you need someone who knows and understands how these things work to be sure the "Fits All" or actually "Fits Most" will be safe to operate and run it thru all the test parameters.

But I would go with @Tim McElwain recommendation since he has more experience with Gas. I'm an oil burner guy

Respectfully Submitted

That was a common gas valve in my area in the 1950's and 1960's. That attachment on the left side of the valve is the safety pilot and could be replaced if you had one in stock. That valve can be replaced with a standard combination gas valve by a tech that knows his job well. There is nothing special about that gas valve except for the added pilot safety attachment.

Thank you, I have heat, the problem is the gas to the boiler doesn't shut off, the boiler will run and run and run providing me with too much heat

JUGHNE

You are saying the fire will never shut off?
Even if you shut off the power supply?
How do you control the heat?

If so, you have a more serious problem then if you have no heat.
If the flame got snuffed out for some reason the gas may continue to flow.

This is the simplest repair/replacement for a gas valve there could possibly be.

I have 2 or 3 of these replacements on hand and I am semi retired.

Also your name plate says natural gas, are you sure you do have NG?
Some older units were converted to LP without any marking stating so.
So if you have no LP tank then it must be NG. This is important BTW.

Also was the lower part of the boiler ever under water?
The gas pipe fittings seem unusually rusted.

The basement wall next to the furnace is wet during the rainy season which is when it's above freezing here which may be the reason why there is alot of rust and that the furnace is over 30 yrs old. 

Yes I most definitely have natural gas, the heat is off right now, because it won't stop running the gas won't stop flowing and will overheat and blowup

JUGHNE

I understand then, you shut off the gas to boiler.
Some people would not, believe it or not.

Simple replacement with basic parts, IMO.

If ever new install insist on at least 4" blocks under new boiler.

You don't have heat. You have a boiler that has a flame inside and you have to manually turn it ON and OFF. If you leave the house you can't leave it ON. So you have no heat!

What I'm saying is that a good gas heat man (from the Gas Company or private contractor) would have this fixed in short order.

Were you able to identify it?

16 days from your first posting and still no repair?
