gorton 1965

papa12603

I bought a dozen of these valves thinking they were regular gorton such as c, d, 5,6 etc. They only say 1965. I know that they are radiator air vents but would like to know how to use them. They all have the same size air vent. For example, the hoffman number 40 can be used in all the radiators so I wonder if that is the case with the gorton 1965. I went to gorton website but they did not have these vents there.

Maybe some pictures of them would help.
Do you have a venting problem?--NBC

The Gorton 1965 I believe is obsolete. Must have been old stock. They don't show it on their website. I don't know the venting rate of the vent. I do know that they don't have floats. To use them just screw them into the rad.

I seen these at my local Johnstone Supply today. They say automatic adjusting. ???

I will post a picture of them.

Fred

Those have a 1/4" pipe/thread. They must be for a main and or a steam appliance of some kind. not for radiators.

Dave0176

Fred the ones I seen are 1/8 pipe tap angle valve.

Here is pic from their web site in the gallery

Fred

Huh, the one I looked at says 1/4" http://knoppix.net/store/Gorton-1965-Steam-Air-Valve-Vent-1-4-_151918349443.html

ChrisJ

Obviously it's a typo, or the 1965 came in both straight 1/4" and angled 1/8"

This isn't helping the OP.

Fred

That is really the question from the OP. What is the 1965 used for? To answer that one has to know what (or which) 1965 he is talking about. Obviously one of these models is wrong

ChrisJ

As had been said, I think we need pictures.
The other issue is, it seems no one knows their vent speed.

Check out the link no info thou.......

Designed for confusion, I guess

Here is a picture of the culprit. Thanks for all the comments. This is an amazing community. I have become hooked with steam and the community behind bringing it back to its glory.

Fred

We still haven't figured out what the venting rate of that vent is. May take a call to Gorton tech support as I haven't found anything that provides specs, yet.

ChrisJ

You can probably get a very good idea by blowing through it and comparing it to other Gortons. There's a huge difference between a 4, 5, 6 , C and D and it's very noticeable just by blowing with your mouth.

Mark N

There used to be a data sheet on the Gorton website for this vent. I think that the rate was either the same as a #5 or a #6.
These vents don't have a float.

ChrisJ

I've heard rumors the floats don't stop water regardless though I've never dealt with it my self.

Mark N

Last winter at work the auto feeder got stuck on and flooded the system. All the vents had floats but still leaked. I attached a picture of the inside of an old 1965 that I had in a spare parts box.

ChrisJ

Apparently, it works absolutely nothing like a normal Gorton other than it uses bimetal and is the same outside shape.

papa12603

Fred thanks! It is a 1/8. Thanks ChrisJ! Thanks to all other looking into this.

Mark N

Now we know why it's called a 1965. Thats the date the patent was filed.

papa12603

And yes, no float in it.

Dave0176

I found this at my plumbing supply.

That chart is on their website as well, and I think it over simplifies the vent selection process, and puts some off the main venting burden on the rad vents. If only more radiator vents used the maid of the mist orifice system, then it would be easier for the DIY homeowner, (or the pro) to get the system balanced.--NBC

It also trims the manufacturing process and store stocking requirements a lot. I'll bet if MOM went away tomorrow, Gorton would start doing this the next day.

ChrisJ

So a 1965 is a Gorton #5 as far as speed goes?


I kind of like their chart, it partially agrees with how my system behaves. The more piping between a radiator and the boiler, the bigger the vent I need because of friction losses.
