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

The BERMAD Model IR-120-54-3Q-X is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower 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-X 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




    • 3-Way Pilot Controlled
        • Opens fully upon line pressure drop




    • 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
