Flow controllers with an integrated control valve have multiple functions integrated in a single product – a motorized control valve, flow limitation and fixed differential pressure controller.
With three functions combined in one valve body, it significantly saves on installation space.
They are used to achieve good control, independent of pressure variations in the system, and offer the opportunity to limit maximum flow in the system. The control valve is pressure-independent and has 100% authority.
In substations with more connected circuits, using a flow controller with integrated control valve enables perfect control of each individual circuit.
It is recommended to place the controller in the return, but it can be also installed in the flow.

FAQ
Can I limit a max flow with a differential pressure regulator?
Yes you can. Open the control valve fully and set the max flow by adjusting the differential pressure. You can also calculate the appropriate differential pressure, but you need to know the exact capacity of the control valve.
We design an installation and need lengths of valves from a project specification.
We produce valves with a standard length. You can also find the measures in our datasheet or download 2D and 3D CAD drawing models from our product presentations. Please go to our product catalog where you will find links to documentation and drawings - follow the below link.
Case stories

The Challenge: Renovate 34 of the city’s largest heating substations
The Solution: Danfoss Leanheat® Monitor enables full substation digitalization
The Results: reduced heat consumption by 10%

In the Wittelsbacher Land near Augsburg the local network in Eurasburg supplies heat to 80 buildings using a wood chip heating system. Danfoss’ substations ensure efficient heating in all building types, and its modern SCADA solution enables remote system monitoring and management.

The Saleska Valley district heating network is the second largest network in Slovenia, dating back to 1959. Since then, the demands have changed significantly and have challenged the hydronic balancing of the system which was optimized with new intelligent controllers Virtus.

SOUTH KOREA: The South Korean National Institute of Fishery Science is enjoying great fuel savings and 20-30% less emissions from its newest research vessel. A special shaft generator solution enabled the vessel to comply with the IMO environmental regulations effective in 2020.

In Europe, 30 percent of all energy consumption goes to heat or cool buildings. Danfoss has the solution to lower energy usage and improve indoor climate by adding a digital element: Leanheat software.

The world’s largest solar heating plant in Silkeborg, Denmark harnesses energy to heat the homes and workplaces of 40,000 citizens. It supplies 18-20% of the annual heat consumption in the city of Silkeborg, Denmark, which has an ambitious target of CO2 neutrality in heat production by the year 2030.
