    PFR valves

    Faster, more reliable and foam-free filling

    The new PFR valve enables the filling velocities to be ideally matched to the product characteristics concerned, which means that even severely foaming products can be very effectively handled.

    New: electronic control system directly inside the valve

    Besides the improved flow characteristics, the PFR valve now incorporates yet another advantage: its decentralised control system ensures that the conventional electronic component cabinet is no longer required.

    The advantages of the PFR valve at a glance

    Increased output

    The bottle is no longer raised by a lift cylinder, enabling the lift cylinder cam to be dispensed with and enlarging the filler’s treatment angle. This means, for example, that the annual output of a CSD filler* can be increased by up to 25 per cent, which adds up to an additional volume of up to 72 million bottles a year.

    Energy and media savings

    The PFR valve operates fully electronically: in comparison to electropneumatic
    filling, compressed air consumption can be reduced by up
    to 30 per cent. So depending on the size of the machine involved, several
    thousand euros a year can be saved in terms of energy costs.

    Improved filling quality

    The new PFR valve enables the filling velocities to be ideally matched to the product characteristics concerned, which means that even severely foaming products can be very effectively handled. Foaming losses in the filling valve are minimised. Thanks to a product preselection feature, moreover, the optimal filling parameters can be easily reproduced. This function can be selected very simply at the touch-screen. There’s also an option for adding automatic function monitoring of the PFR valve.
