Balancing process
Take the plastic cap screwed on the upper part of the valve off. Turn the presetting dial device (see picture 2)
and match the black mark on the swivel part with the value stated on the fixed part of said device (min., 1, 2,
3, max), which shall correspond to required flow rate.
The relation between flow rate and values shown on the presetting dial device are given by the tables stated
on following pages of this brochure (see “Graphs and Tables”).
Using the differential manometer
Cim 726
, check that the differential pressure is higher or the same as the
minimum value reported in said tables. The differential manometer interfaces with the balancing valve
through two sensors placed in the binder points of the valve.
When balancing is achieved, screw the lock for presetting dial completely, preventing any unintentional
rotation.
Screw the plastic cap completely to open the valve and achieve the required flow rate (
Cim 776)
or,
alternatively, assemble the electric actuator for modulating purposes (
Cim 777
).
