Application:
The pressure independent control valve “Cocon QFC” is designed
to be installed in heating and cooling systems with closed water
circuit (e.g. central heating systems, surface heating systems, fan
coil units, chilled ceilings and fan convectors) for automatic flow
control (hydronic balancing). It can also be used for room
temperature control by modifying the flow rate with the help of
actuators.
