Best Valves for Runtal Radiator

Hi everyone,
We renovated a bathroom and are replacing an existing cast iron radiator with a Runtal UF-6-36 to maximize space and trying to select the best valve setup. The install is straight, coming up through the floor. We prefer a manual valve and aren't interested in a thermostatic valve. The Runtal will be installed 2nd from the last radiator in the loop, the last radiator being a bedroom.

I'm often seeing Runtal baseboards installed with no valves but thought the valves were still useful for shutoff, flow and balancing. When talking with Runtal the technical rep stated the only valves with flow adjustment were the VALVE-PC allowing for a 1/4 turn adjustment similar to a standard valve.

At $75 a pair I felt the price was a bit high for such a limited range in adjustment. I also didn't like the idea of being limited to a sweat connection. I looked at some other alternatives and found the Myson LKD16SN valve. What impressed me the most was the Myson allows up to 5 turns for flow and balancing adjustment. And the valve allows a threaded connection. I understand the range might be excessive but the combination of 5 turns, a "re-usable" threaded connection and a price point of $40 a set seems like a smarter option.

Also, I toyed with the idea of installing common valves under the floor from the basement and terminating with nickel plated nipples into the radiator. The appearance would look clean and minimal in the bathroom but the install would be a little comical because the hot water valves are only available in right angle.

Am I over thinking this, probably. Would anyone care to comment or recommend something better?

    Is this being installed in series? What type are the other radiators?

    when I do the runtal towels -- I pipe them direct and use a zone valve with thermostat

    I usually use oventrope valves, work for balancing and stop valves.
    Good luck

    They are just 1/2" npt. You could use standard straight globe radiator valves and chrome nipples and fittings. Or you could get a more compact ball or globe valve and just use black iron or pex and get the pipe covers for the runtal.

    @Zman: Parallel, the other radiators are cast iron of various sizes.

    I agree, any 1/2" valve will work.
    It's is a good idea to have tap handy. Sometimes the Runtal threads need some help.

    We use Myson, Danfoss or Oventrop with Hemp to prevent leaks on the UF Series Rads.
    Caleffi has the 220400A and 221400 A ..They also have 338,342 and the 339 rad valves for the American market...I am guessing that Hemp is not used for these Radiator valves.
    Then again maybe HR can shed some light on these Valves.
