TRVs for gravity hot water system

Ken_31

My aunt has a 101 year old house in Seattle WA that has an oil fired gravity hot water system of unknown age. I believe it was installed prior to 1942 (when she moved in) as she doesn't remember her family ever making changes to the heating system.
The only problem is that the rooms on the second floor tend to get too hot during the winter. There are three bedrooms and two bathrooms on that floor and each has a radiator and they seem to be of sizes that scale to the room size. On the first floor there is one bedroom, kitchen, 1/2 bath, dining room, living room, library, and the front entry. All the first floor rooms are comfortable. The radiators all have manual valves some of which have been replaced over the years and some of which leak if turned below wide-open. I would like to replace at least the upper floor valves with TRV's but want to make sure thats a good idea first and get an idea of where to find them in the Seattle area or online.
The system is currently controlled by a programmable timer thermostat located about in the center of the first floor in the dining room. There is also a basement under about 2/3s of the house and a 3-4 foot crawlspace under the rest.

I know we can get Danfoss TRV's here in the UK for gravity systems. Try them.

TRVs will definitely prevent the upper floor radiators from overheating.

I'm not sure about any on-line retailers. Most all supply houses can get, but they're not "stock" in most areas of the US.
