Pressure Relief/Sustaining Valve IR-430

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

       

       

 

    • Advanced Globe Hydro-Efficient Design
        • Unobstructed flow path

       

        • Single moving part

       

        • High flow capacity

       

       

 

    • Fully Supported & Balanced Diaphragm
        • Requires low opening and actuation pressure

       

        • Excellent low flow regulation performance

       

        • Progressively restrains valve closing

       

        • Prevents diaphragm distortion

       

       

 

    • User Friendly Design
        • Easy pressure setting

       

        • Simple in-line inspection and service
