What is this on my radiator where the valve should be?

[robodelfy]

All my radiators have either a thermostatic valve or manual valve, but this one I don't know whats going on. Can anyone explain?

Thermostatic valve (TRV) with the head missing.

Thanks, so could I buy any TRV head and it would work?

No.

 

[robodelfy]

No.

Ok, any idea what head I would need or how to find out from looking at it?

 

[Mottie]

Is it the same as other ones you have?

 

[vulcancontinental]

Danfoss

I have to other TRV radiators, but they are different and I havent taken off the heads as I wasn't sure how. So maybe tomorrow I should take them off and check if they are the same

Or just post a photo here and we can probably tell you

I posted a photo of the bit without the TRV head, but do you mean post a photo of the other ones? A guy above said Danfoss, which from googling seems like an old one

 

[muggles]

Yes, post a photo of one of the other ones

It is an old one

It is an old one

Thanks, the danfoss ones seem quite expensive compared to many others, can you get some standard generic one that will fit

 

[robodelfy]

Yes, post a photo of one of the other ones

OK so it turns out the other two were the same, and are Danfoss as Vulcan said, photo attached! But any idea how I find a head that fits, as when I google it all kinds of Danfoss ones come up. thanks

 

[dilalio]

Just send the photo to Danfoss and ask them... Its an old Danfoss Randall head but they may have newer types that will fit.
