Main vent valves for low vertical clearance?

It's a two main 1-pipe steam system with one of these vents (pic attached) on the end of each. One of the valves is stuck shut so I'd like to replace both, curious if anyone knows of a nice vent that will fit in here? Vertical hight doesn't seem to be specified on a lot of the ones I've looked at. There is just under 4" of room




thanks

    I should mention: threads are 1"
  • You could always mount the new vent on the underside of the 90 degree ell, on the vertical pipe.
    Do a search for the big mouth vent here, and it will give the dimensions.--NBC

    Big Mouth Is 4 3/4" overall.

    The vari vent is 3 3/4" tall overall. Probably best option. But it's only 1/2" NPT so you'll need room for a bushing. It would be close.

    It would be a nice excuse to put in a tee with a pressure gauge, I'll look in to the big mouth thanks
