Pressure Reducing Valve IR-420-50-bKZ

The BERMAD Pressure Reducing Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand, or varying upstream pressure. It either opens or shuts in response to a remote pressure command.

    • Hydraulically controlled On/Off Pressure Reducing Valve
        • Protects downstream systems




    • Pressure Reducing Servo Pilot Controlled
        • Dynamic integrated needle valve


        • Settable to 0.5 bar; 7 psi




    • Very low hysteresis


    • Advanced Globe Hydro-Efficient Design
        • Unobstructed flow path


        • Single moving part


        • High flow capacity




    • Fully Supported & Balanced Diaphragm
        • Requires low actuation pressure


        • Excellent low flow regulation performance


        • Progressively restrains valve closing


        • Prevents diaphragm distortion
