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.
Features and benefits
Eliminates pressure variations and provide 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
