Product Description

The BERMAD Model IR-120-55- 2 Way Pressure Reducing Valve is a hydraulically operated, diaphragm-actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. It either opens or shuts in response to an electric signal

Features & Benefits

  • Line Pressure Driven, Electrically Controlled On/Off
    • Protects downstream systems
  • Engineered Plastic Valve with Industrial Grade Design
    • Adaptable on-site to a wide 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 the smooth closing
    • Requires low actuation pressure
    • Prevents diaphragm erosion and distortion
  • User-Friendly Design
    • Easy pressure setting
    • Simple in-line inspection and service

Technical Data


Bermad - 120-55-2W - Operation

Opening the Solenoid [1] opens the Valve. The Pressure Reducing Pilot [2] commands the valve to throttle closed should Downstream Pressure [P2] rise above the setting, and modulate open when it drops below the setting. Closing the solenoid causes the Valve to shut. The downstream Cock Valve [3] enables manual closing.
