Determination of the pressure loss in relation to the flow rate.
The values described in the diagram have been obtained with:

an upstream pressure of 8 bar (800 kPa)

the pressure reducer calibrated on 3 bar (300 kPa)

INSTALLATION RECOMMENDATIONS:

install – upstream and downstream of the reducer – the shut-off valves
to perform any maintenance work;

always envisage the application of a filter upstream of the system;

thoroughly clean the high-pressure pipe upstream of the reducer by
flushing several times;

follow the direction indicated by the arrow on the body;

set the reducer to the maximum pressure compatible with the system,
fully open the downstream flush valve to further clean the pipe;

close the downstream valves and set the reducer to the desired
pressure, shown on the pressure gauge that can be applied to the
manometric intake by removing the cap;

flush a few times to check the stability of the setting;

if the system includes tanks or devices with an operating pressure
lower than the pressure of the network upstream of the reducer, when
this is installed always fit the safety valves required to protect the
tanks or devices.
WARNING: When the system is running, the pressure detected by the
pressure gauge may be affected by the overpressure of the heating
system; any adjustments must be performed when the system is not
running and at ambient temperature.
The pressure reducing valve can be installed horizontally and vertically.
