They can be used for adjustment. You can put a TRV vale in without a head and add a control head later if you need it. You need a valve on the supply and return if you are going to shut the radiator off to remove it. Also probably want to drain it in the boiler room somehow before you remove it. There are european valves with a lance that can feed from one end. There are european style dual valves. TRVs will only work if the radiators have some sort of individual supply and return.There are lots of options. If you are heating the whole house and the radiators were sized correctly you should be mostly able to balance things with just the radiator valves. TRVs are a good option in places with varying heat loads like a kitchen or someplace with a lot of solar gain.
