Your guess is correct, and as and extra, most TRV's are bi directional, so can go either side as well.
Ooh...can i jump in and ask;
if i'm adding a rad to a dual pipe system, again does it not matter which side of the new rad i put the TRV on?
the rad i'm tee'ing off has a pressure gauge on the pipe before it goes into the rad. It's this tee to the new rad that i want the TRV on.
I'm assuming this is the flow seeing as it has the combi boiler pressure gauge connected to it?

Bi directional TRV's can go either end. I don't understand your comment regarding a pressure gauge on a pipe feeding a rad?

We have a rad in our airing cupboard and sometime in the past a plumber has put a pressure gauge on the pipe leading from the loft (presumably directly from the boiler) to the rad. There's also a filling loop in there too so i'm guessing they were installed there to avoid climbing into the loft every farts end to check water pressure and fill or empty water from the system (combi boiler)?
So, if the pressure gauge is indeed a remote gauge then i'm assuming that feed in the flow.
That make any sense?
Sorry to hijack the thread btw.
Yes makes sense, although it may not necessarily be on the flow pipe, as it can be on the return. Makes no difference.

Although rad valves are bi directional trvs should be on the flow and lockshields on the return that way you get the correct flow into and out of a rad.
But systems arent usually set up exact so wont make much difference but some bidirectional can be noisy when on the return
