Technical information

Application: The combined control and regulating valve “Cocon QTR” is designed to be installed in heating and cooling systems with a closed water circuit (e.g. central or underfloor heating systems, fan coil units, chilled ceilings, fan convectors etc.) for an automatic flow control (hydronic…
Even where high differential pressure variations “p1” – “p3” occur,

e.g. if sections of the system are activated or inactivated, the differential pressure “p1” – “p2” is kept at a constant level. This way, the combined control and regulating valves “Cocon QTR” have a valve authority of 100% (a = 1). Even during low demand periods with steady control (e.g. in…

Max. differential pressure p1-p3 [bar] Dimensions Nominal setting [m3/h] D Illustr. 4: Max. differential pressure 4 bar (400 kPa) L Pressure test points: The flow-meter “OV-DMC 2” can be connected to the pressure test points. This will determine if the valve is working within the control range. The…
