Features & Benefits

    Inline design

    Inline flow allows high pressure drops without noise.

    Adjustable set-point

    Delivers desired differential pressure ensuring accurate balancing.

    Measuring point

    Simplifies the balancing procedure, increases its accuracy and enables troubleshooting.
