Fitting new TRV heads on existing pipework

[JerLyons]

I am trying to find suitable TRV heads for rads in house I bought earlier this year.

Three rads have the attached pipework which appears to have a TRV pin at the top, but no heads on them, wondering if anyone has seen these before and can recommend a suitable head, or alternatively a suitable adapter for use with different TRV head. Existing pipework has no threading around the TRV pin, hence why I'm struggling.

Any help would be greatly appreciated.

I bought mine from this company. My TRVs are not the same make as yours but the fitting was similar. You will need to know what make your TRVs are. No guarantees but this company stock different heads for older valves.

@pete50 thanks for the response. I don't have a clue which make the TRVs are though. Is there any way of knowing that just by looking at the body without the head?

if you post a pic of the front of tha valve body, it has a brand logo on it and someone will recognise it

It doesn't have branding so I'm not sure if this helps at all really but maybe a closer up picture will help anyway?
