Can't find adapter

Post by stombacco » 13 Oct 2017, 15:06

Hi to all! I bought 2 radiator valves. The adaptors inside the box was useless. Looking at the picture in section C of the manual I was sure my valve was Vaillant and I ordered a set. Today I got the adapters but neither this is suitable. I've attached two photos of my existing vales. Can someone help me to understand what adapter I have to use to install my Netatmo Radiator Valve? Thanks Stefano

Your convertible radiator valves is a Caleffi model .
You miss the original plastic ring, provided with Caleffi thermostatic control head. Look at techincal spec. PDF on Caleffi site
On top of this you can simply place Netatmo adaptor ring, type M30x1 or 1,5 (I do not remember)
Unfortunately the adaptor does not remain strongly attached, because plastic on plastic ring. This is what happened to me...

Hi stombacco, the caleffi ring can be easily found for few bucks. Try googling something like "caleffi 36077"

Can I bump this one up again......

Like many, I have problems securing the valve onto the plastic Caleffi adapter - it too easily pops off.

To me, the 30x1.5mm Netatmo adapter is not a good fit on the thread of the Caleffi part. Does anyone know what the correct thread sizes are on the Caleffi part and on the Netatmo head?
I've tried searching but can't find this particular info.

I feel a metal adapter would be better ( make one) ...but I need to be sure the sizes are right.
