ARI-PRESO Spring acting maintenance-free bellows seal self-operated pressure regulating valve is a spring-loaded differential pressure-control valve. The main applications are Pump protection, application in bypass lines from users, and parallel to piping systems. It secures a minimum flow, avoids higher differential pressures, and flashing in condensate systems.
