is the model you either have or seek. Tunstall Associates carries them but you may be sent to a distributor more local to you. Tunstall is great to work with.

Both the Macon and Danfoss do similar functions and have integral vacuum breakers, a key feature to making these work well.

    steam radiator control valve

    I am supposed to install a danfoss ra2000 on the 1/8" vent of a new steam radiator. I checked an existing radiator and it had a thermostatic valve similar to the danfoss with the letters MMA stamped on the body.
    It had a 1/8"mpt on the horizontal end to screw into the rad., a 1/8" fpt on a vertical to screw the vent into and the adjustable control head connected to the horizontal.
    Where can I find these?
    Can I substitute a danfoss ra2000 with nipples and bushings?

    You're

    looking for a Danfoss 1 pipe steam valve #013G0140 available thru your local wholesaler. This valve includes a vacumm breaker and is different than the other RA 2000 valve bodies, you do not want to bush down. This valve controls by allowing air in and out of the radiator. See attached data sheet.
    Good luck.
