BERMAD Pressure Relief/Sustaining Valve

Model: WW-430

The Model WW-430 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.
