2" Straight (Steam) Rad Valve?

My apologies if this has been answered elsewhere. I searched but was so overwhelmed with hits that assumed I meant 1/2" or 1-1/2" that I had to give up. (Technology is great, except when it isn't.)

Due to constraints too many to list, the silver bullet to my current challenge would be a 2" straight (steam) radiator valve. Like a Watts RA-1-SW but 2".

Has anyone see such a thing "in the wild"?

Current and recent catalogs are silent on the subject. I'm beginning to wonder whether anyone EVER made one.

Thank you.

    Marsh supposedly makes a straight pattern 2" steam valve, but not sure where to source it from.

    Thank you very much!! That's more evidence than I'd been able to come up with.

    I can see it now... "minimum qty: 500" :D

    Just called Marsh. They said, "That's all old information. We only offer the R-100 series. The 101, 103, 105, etc. are all discontinued."

    Nice of them to update their website.

    Then the other shoe dropped. "It looks like the 2-inch R-100G (straight) is also discontinued. The largest we have is 1-1/2 inch."

    DOH!

    Still, thank you for your suggestion.

    A gate valve may be used, with the stem horizontal, or a full port ball valve.
    If this is to be used on a one-pipe system, then the valve should never be closed, except for repairs. Instead, you can turn the air vent upside down, (at least with Hoffman vents, and possibly other makes as well).—NBC

    That's been listed for years, I wonder how long it's been "old information" and "discontinued"?!

    Looks like creativity is in your future.

    So true! If necessary, I'll start another thread with the particular scenario that prompted my search for a 2-inch straight radiator valve and leave this one for any reported sightings of the now rare beast.
