Nominal pressure: PN16
Valve material: EN-JL1040,EN-JS1049,1.0619+N,4.4408
Connection: Flange
Fluid medium: Gases, Vapours and Liquids

Model Category


ARI-PRESO Spring acting maintenance-free bellows seal self-operated pressure regulating valve
1）Product design
The compact structure design of spring loaded,bellows sealing and throttle valve head makes the product adjustment more exact and easy.
2）Pressure range
0.5-1.5bar；1.0-3.0bar；2.0-5.0bar；4.0-10.0bar
3）Product application
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.
