Pressure Sustaining Valve IR-430-XZ

The BERMAD Model IR-430-XZ Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that it sustains minimum preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure.

Product Features & Benefits
    • 3-Way Hydraulic Actuated Pressure Sustaining Valve
        • Controls system fill-up

       

        • Sustains upstream line pressure

       

        • Opens fully upon line pressure rise

       

        • 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
