High-Risers in Belye Rosy, Krasnoyarsk, Russia

The involved project includes two high-rise buildings of 25 floors and one U-shaped building of 11 floors. The facility has dynamic valves fitted on each pipe from heating manifolds installed in the two-pipe radiator system. FlowCon AB with E-JUST was chosen working as flow limiter within a given working pressure range and pressure/temperature plugs on the housing offers the possibility of measuring the pressure drop across the valve and thereby verify flow.

The valve assembly includes an E-JUST insert and a valve housing and is supplied as a complete solution for balancing the heating system now as well as a flexible solution for future modifications requiring changes in the heating system.

Operating pressure range: 17-200/400 kPaD (divided over high and low ΔP ranges).
Flow range: 100-5830 l/hr (depending on the selected insert).
Accuracy: greatest of either of ±5% of controlled  flow or ±2% of maximum flow.

Each insert holds a minimum of 41 different max. flow rates. This provides the client an easy access to change flow without dismantling the system if such a need arises during operation. Design flow is set directly on the insert using the FlowCon key. The set value on the insert corresponds to a setting in the technote flow table - nice and simple.

The insert-type valves and the availability of caps for flushing the system, greatly supports to the future operation and service of the system.

The use of FlowCon’s dynamic valves has ensured a clear and stable distribution of flow across individual areas of the building, eliminating local system overload. It is not unimportant to note that commissioning time was also decreased to a minimum.
