Application / Sizing The pressure regulating valve PRESO is a spring loaded differential pressure-control valve. The main applications are: - Pump protection: PRESO inserted parallel to the pump, this secures a 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 to higher differential pressures. - Pressure maintaining valve to avoid the flashing in condensate systems.
