TECHNICAL INFORMATION
Pressure independent control balancing valves
CIM 776 and CIM 777
Description
Balancing valves
Cim 776
and
Cim 777
are
designed for automatic balancing of heating
and cooling installations, regardless
pressure fluctuations under service, which
might occur due to flow rate changes in the
installation.
Thanks to their unique design, these valves
are able to perform the following functions:
•
REGULATION
: selection of required
flow rate within the operating range.
•
CONTROL
: constant flow rate
independent of pressure fluctuations.
•
MODULATION
: “Full authority” flow
rate modulation for temperature control
(
Cim 777 series
).
Automatic balancing valves
Cim 776
and
Cim 777
are made of “CR – Corrosion Resistant” brass according
to ISO 228 standard and are suitable for working pressure up to 25 bar, within the temperature range from
0°C up to +120°C.
Cim 776
e
Cim 777
ranges are available with two pressure levels:
•
“Low Flow”:
from 78 l/h up to 1722 l/h;
•
“High Flow”:
from 244 l/h up to 8586 l/h.
