Steam radiator valve heights
Hi all, happy new year! I've gotten some very useful advice here and I wanted to give something back. I recently learned that not all steam radiator valves are the same height, and it's not just an old-vs-today difference, they're made today in different sizes.
In these pictures, front and back for 1 1/4" and for 1", a Bluefin valve I got from supplyhouse is on the left, and a Marsh valve from nyrpgroup is on the right. The Marsh valves have a spec sheet which gives the dimensions from the bottom to the centerline of the union, but the others don't; you can see they're about a ¼" shorter. I think the pictures got put in a random order when I uploaded them, unfortunately.
Hope this helps someone get a replacement valve that matches and avoid having to rework the pipe!
