Pressure Reducing and Sustaining Control Valve IR-123-55

The BERMAD Model IR-123-55 is a hydraulic operated, diaphragm actuated control valve that performs three independent functions. It sustains the preset minimum upstream pressure, reduces downstream pressure to a constant preset maximum, and it either opens or shuts in response to an electric signal.

    • Hydraulic Pressure Control with Solenoid Control
        • Protects downstream systems


        • Sustains supply line pressure and controls system fill-up




    • Engineered Plastic Valve with Industrial Grade Design
        • Adaptable on-site to a range of end connection sizes and types


        • Articulated flange connections eliminate mechanical and hydraulic stresses


        • Highly durable, chemical and cavitation resistant




    • hYflow ‘Y’ Valve Body with “Look Through” Design
        • Ultra-high flow capacity – Low pressure loss




    • Unitized Flexible Super Travel (FST) Diaphragm and a Guided Plug
        • Accurate and stable regulation with smooth closing


        • Requires low actuation pressure


        • Prevents diaphragm erosion and distortion




    • User-Friendly Design
        • Easy pressure level setting


        • Simple in-line inspection and service
