Hello,

I have a question about La Scala butterfly restrictor.
Does flow restrictor which are in a group head of Expobar leva machine fit to la Scala butterfly?
the link to restrictor:
http://www.cremtechnical.co.uk/C50020000.html

I find a topic with a similar problem. But the guy who own the Butterfly did not mention or shown what dimensions are group head flow restrictor.
And interesting he put in la Scala lower tube and not in upper tube of thermosiphon, otherwise it didnt work ok.

Topic from 2009:
