The Bermad Model 730 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.
