Old style fin radiator needs help!

Hi, my house has the old style fin radiator. Can anyone help me to identify what it is called? The valve underneath is has water leaking. I am trying to find a replacement part. I managed to find one good one with the cap on it. But I need to have the exact information in order to find the part online?

After long googling on google, it looks like Legend Valve 110-217. But my concern is can the male part connect to the fin radiator leg? How can I tell the the correct size I need that allows me to connect the radiator leg to the male circulator valve?

Thank you all for your help!

    The bottom end that attaches to the pipe coming up through the floor is a 1/2" sweat (soldered)
    connection.

    If you find a new valve with a sweat connection you can solder it on the bottom. If you get a threaded valve then you use a 1/2" copper x male sweat adapter on the bottom.


    As far as the top connection goes you take that union between the valve and the spud apart by unscrewing it.

    Problem is when you replace the valve your going to need to replace the spud as well because it comes matched wit it's own valve.

    The way I would approach those it to sut off the water to the boiler and drain the boiler down. The take both union nuts apart and pull the convector (finned element out.

    Then do your soldering and install new valve on the two pipes. Remove the old spuds frm the convectors and install the new spuds

    Then set the convector back in place. Dope the unions up with "anti seize" available at an auto parts store

    you will need a spud tool to remove the spud from the convector. Those spuds can be difficult to remove.

    How well do inside pipe wrenches/nipple wrenches work on those once the lugs break off?

    If the lugs break off another option is to remove and replace the 3/4 X 1/2 bushings with the broken spuds inside.

    In any case be sure to use a bigger back up wrench than the turning one.
