Functionality and usability enhancements
make the Intelligent Valve even more efficient. As a 3-port valve, it can now
be used in mixed circuits, which offer easy hydronic balancing and require only
minimal investments due to the absence of a main pump in the source circuit. A
new differential pressure control counteracts pressure fluctuations in zones.
In older plants, this allows dynamic hydronic balancing to be upgraded quickly
and easily without having to replace all the valves, thus expanding the scope
of application of the Intelligent Valve. In new plants, the zones equipped with
differential pressure control offer optimized operating conditions for the
valves. Using newly-added flow temperature controls and weather-compensated
heating circuits, the Intelligent Valve performs automation level tasks and
reduces the load on or even eliminates the need for comfort controllers. By
reducing the load on comfort controllers, the Intelligent Valve allows more
complex plants to be installed at lower investment costs. In situations where
comfort controllers are replaced altogether, the Intelligent Valve can perform
simple control tasks.
Newly available spacers for the Intelligent
Valve ensure improved insulation, for instance, for the flow sensor in cooling
applications. The newly implemented Delta-T (
DT) limitation control, which is primarily suited for air conditioning units and large fan coil units, offers increased efficiency. This feature limits the temperature difference DT across the cooling coil controlled by the Intelligent Valve. As a result, the chiller or the heating pump always operates above the defined DT - design, ensuring maximum efficiency and saving electrical energy.
