Pat, would these valves also be what I'd want for a Mouat system? Some of our originals have been replaced.

    Broomell Vapor Valves & traps

    Who makes a good substitution for Broomell radiator valves and trap ells, and where can I get them?

    Any good thermostatic trap will work

    same for any good rad shutoff. I'd use a trap with a smaller flow rating like the Hoffman 17C, this will be a closer match to the air holes in the Broomell return ells.

    replacement valves

    Hi Gordon,

    If you need to replace a radiator valve, and not the return ell ( there are no moving parts, so why would you replace? ), then make sure you purchase one that can be internally adjusted, like the Broomell. The two manufacturers that I know of are Marsh and Mepco (the old Dunham-Bush).

    Best regards, Pat

    Pat, thanks for the info. This project has the Broomell return trap ells with the orifice. I would like to leave them in place but there is no access to the orifice unless I pull the radiators. I thought that it would be worth the expense to install steam traps. Then I can at least check and clean them in the future.

    just back from the library

    Hi steam bunny,

    Yes, the Mouat system used a graduated valve that could be adjusted to match radiator capacity. I wasn't quite sure, so I checked the library feature of this site. Isn't Dan wonderful?

    Right there in glorious black and white from out of the past, the information that I needed. Mouat was like so many other two pipe systems, vapor especially, that used an internally adjustable valve to balance and regulate steam flow.

    If your radiator valves have been changed through the years, and replaced with regular handvalves, then you should consider the purchase and installation of new valves with the internal adjustment feature.

    Best regards, Pat

    As long as the system is relatively clean

    you won't have trouble with those Broomell ells. A few small pieces of dirt will just wash thru the water seal portion, bypassing the orifice.
