AUTOMATIC FLOW 
BALANCING VALVE

790

Main features:

 

 

Cim 790 is used for balancing the flow in cooling, heating and domestic water systems.
Cim 790 is an automatic balancing valve with following features:
•  Constant flow regardless system pressure fluctuations;
•  System balancing is assured automatically, even under fluctuating pressure condi-

tions;

•  Automatic balancing is achieved by means of cartridges that provide constant flow 

within a fixed range of differential pressures;

•  The self-cleaning cartridge design makes very difficult for any particles to accumulate 

and compromise the accuracy of the valve.

It is supplied with internal thread.
It is made of  “CR” brass (“CR” - Corrosion Resistant).
This article is made in compliance with the quality management requirements of ISO 
9001:2008 standard.
All articles are tested according to the EN 12266-1:2003 standard.
It can be used in a wide variety of sectors: heating, air conditioning, water, sanitary systems 
and generally with any non corrosive liquid.
