M28 TRV to M30 Hive TRV

[Al Craft]

Hi - I need to convert a 28mm valve to 30mm. I purchased the attached converter, which screws on fine (if I remove the black plastic spacer), but the thread is not deep enough, so that pin on the adapter, does not engage with the valve pin.

Can anyone identity the valve / suggest an alternative adapter, please?

Many thanks

Just change the valve, much simpler

Thanks - but changing the 10 odd valves is probably out of my skill set and the cost of getting someone to do that, will be far higher than if I can source the correct adapter.

If someone can please identify the valve, I think I can find the adapter.

Nothing written on the old trv head? Where did you get existing adapters from?

The TRVs are Drayton (I think TRV3).
Does that mean the valves are also Drayton (I’m new to this)?
The adapters were purchased from Low Energy Supermarket https://lowenergysupermarket.com/
From looking online, it appears Drayton don’t make a converter - but I could be wrong.
Hopefully another company does make such an adapter?
Thank you

Adapters seem ok, so maybe speak to Drayton Technical? I’m sure they did a YT video on this recently.
