A full-control mixing valve with adjustable bypasses
enables renewable heat sources to be used with no loss
in efficiency. The Grundfos UPM3 25-70 130 circulator
Provides constant pressure regulation for stable circuit flow
rates ensuring consistent heating performance across all
active circuits. The Circulator isolation valve
Prevents water bypass during the manifold filling process,
ensuring air is efficiently removed from all circuits and
minimises water loss during circulator replacement.
