Pressure-independent control valves

Flow controllers with an integrated control valve have multiple functions integrated in a single product – a motorised 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.

Features and benefits

Eliminates pressure variations and provides optimum operating conditions with improved temperature control quality

Made for demanding systems, resistant to corrosion, cavitation and dirt

Connected system is protected against pressure surges, fluctuations, cavitation and noise

Differential pressure and flow controllers in district heating or cooling systems (variable flow)

Balance your network, save energy and improve end user comfort by hydronic balancing and control of district energy networks.

FAQ

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 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.

    Leanheat makes buildings smart

    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.

    Solar heating plant reduces CO2 emissions by 15,700 tonnes annually

    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.

    First ever district heating system with substations in Turkey

    600 residents in the town of Soma in Western Turkey now enjoy the comforts of a reliable and cheap heat supply from the town’s brand new district heating system. 

    In the coming years, more than 8,000 households will be joining the system that exploits the excess heat from the municipal power plant – a great improvement from the charcoal boilers of the past, and much less expensive.
