General Information
The JRG bypass mixing valve is a compact mixing valve for potable water installations consisting of
backflow preventer, bypass, shut-off valve and control valve for untreated water addition. The versions
DN40 and DN50 do not only feature a fixed but also a volume-controlled untreated water addition.
In case of malfunction, please contact your local sanitary expert.
Recommendation
In order to protect the JRG bypass mixing valve as well as the entire domestic potable water system
from particulate matter and impurities from the mains, we recommend installing a central JRG fine
filter (type 1830 - 1871) with a filter unit of 100 µm.
