    The pressure regulating valve PRESO is a spring loaded differential pressure control valve . The main applications are :

    • Pump protection : PRESO is installed parallel to the pump, this secures minimum flow.
    • Application in bypass lines from users, e.g. heat exchanger in thermal oil systems to sustain a minimum flow.
    • Parallel to piping systems to avoid higher differential presure.
    • Pressure maintaining valve to avoid the flashing in condensate system.

    Selection of possible applications are industrial installation, processing technology and manufacturing plant with flow media such as liquids, gas, vapour and steam.
