Pressure Reducing Valve IR-120-54-3Q-b

The BERMAD Model IR-120-54-3Q-b is a hydraulically operated, diaphragm actuated control valve that accurately reduces higher upstream pressure to very low and stable preset downstream pressure. It is a Normally Closed valve that opens in response to a remote pressure drop command and shuts in the absence of that command. The BERMAD Model IR-120-54-3Q-b also serves as a Pressure Relief Valve protecting the system even when in closed position.

    • Normally Closed PRV with Relief Override Feature
        • Protects downstream and upstream systems

       

        • Closes upon control failure

       

        • Amplifies and relays weak remote command

       

       

 

    • Pressure Reducing Servo Pilot Controlled
        • Dynamic integrated needle valve

       

        • Settable to 0.5 bar; 7 psi

       

        • Very low hysteresis

       

       

 

    • Engineered Plastic Valve with Industrial Grade Design
        • Highly durable, chemical and cavitation resistant

       

        • No internal bolts and nuts

       

       

 

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

       

       

 

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

       

        • Prevents diaphragm erosion and distortion
