Features and benefits

  • Flow controllers group
  • Flow controllers (Q)
    The right amount of energy for all consumers

    A flow controller consists of a differential pressure controller and a flow restrictor (manual balancing valve) integrated in a single valve body. Differential pressure controllers maintain a fixed differential pressure over the flow restrictor. This ensures automatic flow limitation regardless of pressure variations in the system.

    The flow controller cannot be used to control differential pressure over the system or control valve.

    Typical applications for flow controllers are:

    • systems where differential pressure variations are very low
    • systems where the substation is owned or maintained by the end-user or facility manager and where the flow controller is the only solution for the District Heating Utility

    It is recommended to place the controller in the return but it can also be installed in the flow. These devices are used to ensure hydraulic balance in the primary DHC network.
