Pressure independent control valve - PICV717

717
Cim 717 balancing valves are designed for automatic balancing of heating (LPHW) and cooling systems, regardless of fluctuating pressure conditions of the system. Cim 717 is available in DZR brass.Thanks to its unique design, Cim 717 valves are able to perform three functions, in detail:
REGULATIONSelection of required flow rate;CONTROLConstant flow rate regardless of pressure fluctuations;MODULATION“full authority” flow rate modulation (Cim 717-PRO, Cim 717-3P & Cim 717-TH);
The main features of Cim 717 PIC balancing valves are as follow:
Easy selection of required flow-rate using pre-setting dial;Automatic balancing in the event of fluctuating pressure conditions in system branches;Flow rate modulation along the whole electric actuator stroke;Flexibility if the system is modified after the first installation;Reduction of balancing costs, improved energy saving and high environmental comfort;Reduced installation dimensions thanks to very compact valve construction, which does not re-quire inlet and outlet straight pipelines to stabilize the flow;Modulation by control of the return temperature (Cim 717-TH);Version with blind plugs (Cim 717P);Face to face standardized dimensions; Pressure class: PN25. Temperature: -10°C÷120°C

Typical installationsCim 717 is suitable for variable volume system to control fan coil flow rate directly. Below a typical installation: in each moment the flow rate is the required one and there will be no extra-flow due to the pressure fluctuations.
