Re: New steam heating retrofit method
@ariccioyou want to regulate the flow of steam entering the radiator, not restrict the flow of air and Condensate exiting the radiator.
A packless orifice supply valve makes balancing a 2 pipe steam system simple.
By throttling the supply you can deliver just enough steam that the the radiator condenses all the steam before the last section heats.
Steam trap never closes because steam never reaches the trap element. Therefore no steam can make it to the dry return.
A steam trap to me, should be looked at more like an insurance policy, in the event someone changes the adjustments to the supply valve, the pressuretrol malfunctions, for whatever reason, the heating cycle is excessively long, ect...
Adding a vacuum pump does decrease pickup losses by lowering the pressure, water boils faster and fills the system faster.
After the system is filled, the vac pump turns off and a natural vacuum forms due to the condensing steam.
At the end of the heat cycle, the burner turns off, a Solenoid valve isolates the vacuum, Preventing air from being pulled back in, the steam condenses, but more importantly, condenses faster in radiators that are in colder areas of the building. Any steam being produced thanks the the natural vacuum lowering the pressure, will be drawn towards the coldest spots in the system, making a naturally balanced heating system, without a ton of thermostatic controls.

Re: Connecting Radiator to Copper Supply/Return Lines - What adapters?
Couldn't you use it for one side if you moved the radiator over? If centering for aesthetics I can understand.
The male adapter you are looking for it https://www.amazon.com/Everflow-FCMA0012-5-Adapter-Fitting-Connections/dp/B016Y8MS0G
It will be labeled as FTG (fitting) x Male Adapter. or male sweat
If you have 1/2" connections on the rad, assuming european style?
They usually have valve sets straight/angle for your brand like

1/2" isn't too common, mostly ran in 3/4". you'll be able to find the 1/2" in sweat online
Just put a male adapter, don't need brass nipple.

Re: Connecting Radiator to Copper Supply/Return Lines - What adapters?
A common 1/2" copper to male adapter is male NPT, by copper hub.
Both male and female copper adapters are also available as street versions. meaning the copper sweat end goes into a fitting instead of over the tube.
You can also find ell versions of copper to male adapters. They are rare but street copper ells X npt male or female are also out there.
The bottom left female fitting kinda looks like a street version in your pic.
I think copper press fittings are also available in standard and street versions, for NPT transitions.
I'd look for the least amount of threaded connection solution.

Extreme Left Jaw Pain leads to many things.....and there is more!
This is to point out a little known symptom of bad problem ahead.
Two weeks ago at 2 AM I was awaken by extreme left jaw pain, some left shoulder and minor left chest pain. IIRC, BP pushing 200 PSI.
We go to the local hospital 10 miles away. Within 30 minutes the Life Flight Helio is enroute. Get a 100 mile ride in 45 minutes.
Triple heart by-pass the next day.
Come home 5 days later.
I have had jaw pain occasionally when walking some distance and never thought much of it.
Was on no meds at all, good BP and quit smoking about 30 years ago.
But overweight and gaining as I do little real work lately and probably little in the future.
So just throwing this out as an additional warning sign that is seldom mentioned.
