In past house had used Maid o mist vents with interchangeable screw on caps..but I have come across an item that looks of high quality but unconventional.... VARIVALVE by Heat-Timer Corp in Fairfield NJ.

It has a sliding variable thing on side.

Has anyone used them and will they out perform Maid O Mist?

This sliding feature would be great to adjust each radiator some what.

Thanks

    They are supposed tobe good vents.....

    many of the top pros use them.  However, I believe they vent waaay too fast.   This can cause uneven heating, banging radiators and other problems.  I recommend large main vents, with small radiator vents, like the Hofman 1A adjustable or Ventrite adjustable.

    There was an error rendering this rich post.

    I have used varivalve vents on large steam radiators and found that they work very well. I can't say that they are any better than Maid of Mist #D unless you need to make a lot of adjustments. They certainly cost a lot more.
