PRODUCTION:
Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. When installed as a circulation valve, it relieves excessive line pressure when above maximum pre-set.
APPLICATIONS:
Pump Overload and Cavitation Protection
Discharge pressure, preventing pump overload and cavitation damage caused by excessive demand
limit pump flow by sustaining pump differential pressure
maintain the main valve upstream water supply pressure
DRIVE MODE:
Hydraulic power
FEATURES:
Hydraulic pressure driven- independent operation
Flexible design - Easy addition of features
In-line serviceable - Easy maintenance
can save installation space
High stability and accuracy
