Steam radiator vents

Dave Stroman

I would like to start using Gorton steam vents. For those of you who are familar with them, you know that they make a #4, #5, #6, C, and a D. Each with an increasing amount of air being vented. But they also a model #1965. They do cost less and I would like to know how they are different from the others.

I believe

the 1965 lacks a float. Spend the extra money.

Thanks Steamhead. I did just get off the phone with Ken at Gorton. He helped a lot. Do you use the Gorton radiator valves? Which one do you use the most, or do you use them all? I am ordering some from a place I found on line as we have no local suppliers. Probably will order some of the C's and a couple of the #2's.

You'll use lots of Gorton #2 main vents

especially if you calc vent sizings by Gerry Gill & Steve Pajek's charts. We just ordered our second dozen #2 vents this fall, and will likely burn thru those rather quickly.

For radiators, I use the Gorton #4 on the very smallest ones. Next sizes up are the Hoffman #40, then the Gorton #5, and for the largest rads the Gorton #6. A wide-open Hoffman, Vent-Rite or Dole adjustable vent roughly equals the #6. In some cases we need to go larger, using a Gorton C or D, but that's rare if the mains are properly vented.

If the user wants to be able to vary the heat in a particular room but doesn't want TRVs, the Vent-Rite #1 is a good choice as it can be adjusted without tools, even shut off completely. It's best to use a Vaporstat with this setup, higher pressures will cram more steam into the rads by compressing the air.
