6 im 790 Threaded automatic flow balancing valves alancing valve im 790 is designed for automatic balancing of heating and cooling installations. Automatic balancing is achieved by means of cartridges that provide constant flow. The wide selection of cartridges is able to match every flow requirement from a minimum of 0,007 l/s (7 KPa min. Δp) up to a maximum of 3,154 l/s (44 KPa min. Δp). im 790 can be used either in constant flow or variable flow system, assuring that specified flow would not be exceeded. Automatic balancing function is performed with innovative and patented cartridges with incorporated fixed orifice. The automatic function of im 790 eliminates the manual balancing of the system, allowing possible inspection by contractor. The cartridge can be easily removed from its seat even with installed valve, allowing easy flushing of the installation and possible flow modification required after first installation. The use of automatic balancing valve on terminal units of the system avoids the need of other balancing valves on the main circuit or on system branches. alancing valve im 790, is made of R brass and is available in sizes from ½ up to 2 Working temperature range of the valve is between - and 1, with maximum operating pressure PN The main features of im 790 are as follows: The cartridge is removable from the valve body and can be changed, inspected and cleaned without breaking the main piping. No special tool is requested for removal of cartridge; System balancing is assured automatically, even under fluctuating pressure conditions; More compact installation with automatic balancing valves not requiring straight pipe to obtain linear flow at valve inlet and outlet; ecrease of installation costs, due to energy saving and cut off cost related to system balancing. artridge performance is not affected by debris. The self-cleaning cartridge design makes very difficult for any particles to accumulate and compromise the accuracy of the valve; Energy saving due to elimination of excessive flow; Increased comfort thanks to more accurate flow distribution with better performance of system regulating valves. 790 THREAE AUTOMATI FLOW ALANING VALVES im 790 Grms.

7 im 3790 Flanged automatic flow balancing valve Wafer style automatic flow balancing valves im 3790 are particularly designed for cooling and heating systems. The special cartridge assures system balancing even under fluctuating pressure conditions. The available cartridge range can meet flow rate requirements ranging from a minimum of 1,061 l/s up to 12,0 l/s. Since inside the body valve quantity of cartridges may change according to the project flow rate, im 3790 valves are able to meet flow rate requirements ranging from a minimum of 3.8 l/h up to a maximum of l/h. If a full flow capacity is not required, but rather only a portion of it, blind caps can be fitted instead of cartridges. Automatic balancing function is performed with innovative and patented cartridges with incorporated fixed orifice. im 3790 valves are made of ductile iron GGG40 with flanges according to EN/ANSI standards. Wafer style automatic flow balancing valves im 3790 are available in sizes from up to 0. Working temperature range is from - up to 110, with a maximum working pressure of PN. Wafer style automatic flow balancing valves im 3790 are supplied with mm length binder points. From the valves are supplied with a threaded hook to be screwed on the body. These valves work properly within a range of differential pressures included between a minimum value (specified in the table hereafter reported) and a maximum value of 600KPa. Minimum differential pressure can be measured out with the binder points on the valve ve body The main features of im 3790 are the followings: System balancing assured automatically even under fluctuating pressure conditions; More compact installation with automatic balancing valves not requiring straight pipe to obtain linear flow at valve inlet and outlet; artridge performance not affected by debris.

The imdronic 726 is supplied in a conve- nient carry case. Accuracy The imdronic 726 uses a sensor calibrated to points and protected by SP tecnology allowing the use of sensors most appropriate for the measurement ranges experienced in HVA and not compromised by the need for sensors selected for high over-pressure with their poor accuracy and resolution at low dp readings. Accuracy is better than 1% or Pas- cals with system damping to further improve reading confidence on un- stable systems. 217 San Maurizio d Opaglio (NO) - Italy - Via Torchio, 57 -.P. 106 Tel Fax: / skype: cimberiosk1, cimberiosk2 info@cimberio.it opyright - av.
