5 Construction and function

5.1 Survey and functional description
The pressure independent control valve "Cocon QFC/QGC"
is a valve combination consisting of an automatic,
differential pressure independent flow regulator (with manual
nominal value setting) and a regulating valve. The regulating
valve can be equipped with an actuator.
