Flow Rate/Pressure Drop Characteristics - Baxi LUNA SAT RCZ-MB Installation And Operating Manual

6. FLOW RATE/PRESSURE DROP CHARACTERISTICS

These models are fitted with a balancing valve (figure 6). This device is used to balance the flow of water circulating in the
single module in case of non-optimal distribution in the inlet pipes.
Figure 5 shows the Flow Rate – Pressure Drop curve with balancing valve in the wide open position.

Figure 6 show the curves regarding the HYDRAULIC HEAD LOSS (mH2O) against the WATER FLOW RATE (l/h). To set
the curves, close the valve by turning the knob fully anticlockwise. Turn the knob 1 turn clockwise to set the curve A. The
other curves are each a successive 1/2 turn clockwise from A to H (FULLY OPEN).
