I have some white ones that come with circulators, however that black is a high temperature version, here is the #.

I was disappointed to find out my outside reset drops the boiler temp below 140 degrees. I talked to the manufacturer and he said don’t worry you won’t get any condensation. I’m not sure I buy that one!
Thank you bob for the part number.

Do you know what size you need? metric sizes.
I believe Neoperl has a branch US in Waterbury, CT

At this point I’m going to look for another brand flocheck valve.
Thanks for trying.

I found out taco sells the exact part but black instead of white but the same part number.
