Installation
12.2.1 Pressure drop in mixing valve
The diagram below shows a drop in pressure in the mixing valve.
Start with the heat requirement in kW (e.g. 15kW), then move vertically
to the selected ∆t(e.g. 10°C). Then move horizontally to the line for the
EcoZenith i250 mixing valve = line6.3DN20. The reading for the pressure
drop is taken from the scale directly below (4 kPa).
For EcoZenith i250, see valve DN20.
