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.

  • Line Pressure Driven Pressure Relief/Sustaining Valve
    ❏ Controls system fill-up
    ❏ Sustains upstream line pressure
    ❏ Relieves excessive pressure protecting pump and system
    ❏ Prioritizes pressure zones
