Pressure Reducing Valve IR-220-bZ

The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that accurately reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand or varying upstream pressure.

    • Line Pressure Driven, Hydraulically Controlled
        • Protects downstream systems




    • Pressure Reducing Servo Pilot Controlled
        • Dynamic integrated needle valve


        • Easily settable to 0.5 bar; 7 psi


        • Very low hysteresis




    • Plastic Globe Hydro-Efficient Valve
        • Unobstructed flow path


        • Single moving part


        • High flow capacity


        • Highly durable, chemical and cavitation resistant




    • Unitized Flexible Diaphragm and Guided Plug
        • Excellent low flow regulation performance


        • Prevents diaphragm erosion and distortion




    • Fully Supported & Balanced Diaphragm
        • Requires low actuation pressure




    • User-Friendly Design
        • Simple in-line inspection and service
