Replacing TRV and lockshield valves

[pal123]

I am going to replace the piping to the rads from 10mm microbore pipe to 15mm pipe.

The existing rads have TRVs and lockshield valves either end.

I would like to know if I can reuse either the TRV, lockshield or both with the new 15mm tails.

Here are photos:

2) Lockshield valve with 10mm microbore,

Is there a way to tell if I can reuse the existing TRVs and/or lockshield valves? Or do I need to replace the lot with 15mm equivalent? Thanks

The lockshield in your pic will not accommodate 15 mm pipe.
Either buy new or convert your 15 mm to 10mm just before the rad.
I can't make out the TRV ,pic is too out of focus ,but I suspect it is for 15 mm ,but has a reducer set in it to take the 10 mm
