Ah ok that makes senseJyst remove the bleed vave at the end above the LSV and leave out, after first ensuring that both the TRV & the LSV are closed, the open the TRV fully, this proves that you have a good flow from/via the TRV, close the TRV and open the LSV fully, this then proves that the LSV has a good flow. All this proves is that both valves are working as they should.
Just to confirm i only have one bleed valve on the trv sideJyst remove the bleed vave at the end above the LSV and leave out, after first ensuring that both the TRV & the LSV are closed, the open the TRV fully, this proves that you have a good flow from/via the TRV, close the TRV and open the LSV fully, this then proves that the LSV has a good flow.

Is/was the full length of the rad top warm/hot?.Hello guyS
I have not tried what youbsaid
But i have felt the first three columns are warm and the bar across atthe bottom is warm
The rest 11 bars towards right mostly top and middle area are cold
This diverter is 145mm long and inserted at the inlet end.Is/was the full length of the rad top warm/hot?.
"Ordinary" single+double pannel rads start off heating initially like that. If you bring a rad into service with the CH water already up to temperature you will see this effect. The hot water will rise up in the first say150/200 MM length of the rad at the inlet end, it will then get hot all along the top and gradually heat the whole rad from the top down.
