Description

The Bermad Model IR-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 preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure; when installed as a relief or circulation valve, it relieves line pressure in excess of preset.
