Steam Radiator Control Valve

Hello Experts, Dave Berry here and I’m back with some answers to some questions you guys asked me back on February 28th. You may recall that I have a non working radiator and the control handle would not turn - as if it was stuck. I would like to unscrew the valve top and get inside but hope you can steer me in the right repair direction. Also, I have some new photos to better explain what I’m working with.






I cleaned the paint off the valve and now know it is a Webster Sylphon. The radiator is a 24” Peerless.






The trap is also a Webster, HB512

I noticed when I removed the handle there was a broken spring. I’m not sure the purpose for this.



Your hunch about a crack in the valve to radiator union nut was correct. It has a crack. This may have happened when the radiators went removed and painted then reinstalled. I would like to fix the valve in place and not remove it, if possible.



A surprise happened when I was back at this job. The contractor found an old valve in the bone yard. It appears the valve has a screw type stem, like many plumbing valves. I am wondering if the threads may have debris in them and this is keeping the stem from turning. I’m also curious about the ‘flat washer’ material at the base of the stem.




Any thoughts you guys have on moving forward fixes (and precautions) will be super helpful. You can’t imagine how greatful I am! Thank you.

Sincerely,
Dave Berry, Central Alabama

    @DaveBerry I gotta tell you. I wouldn't try to repair the valve . I would replace it. Considering the crack on the spud and the other damage on that valve, its looks like it's time to install a new valve. The trap on the other hand can be rebuilt.

    Very nice radiator setup you have there by the way.

    @DaveBerry , IIRC I think @Gordy rebuilds those valves and may be able to give you some guidance/assistance.

    but its the spud nut thats cracked, correct? Unless you have another, that was not standard thread.

    I'd bet the trap element is bad and that's why the radiator doesn't heat. You can get parts for these traps from Barnes & Jones or Tunstall.

    Perhaps you should consider a Macon non electric self contained rad valve. www.maconcontrols.com
