Flow Control and Pressure Reducing Valve IR-172-54-bD

The BERMAD Model IR-172-54-bD is a hydraulically operated, diaphragm actuated control valve that limits system demand and reduces downstream pressure to constant preset maximum values. It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.

    • Hydraulic Pressure Control, Normally Closed
        • Closes upon control failure

       

        • Limits fill-up rate and consumer over-demand

       

        • Protects downstream system

       

        • Amplifies and relays weak remote command

       

       

 

    • Adjustable Servo and 2-Way Pilots
        • Very low hysteresis, easy setting

       

       

 

    • Engineered Plastic Valve with Industrial Grade Design
        • 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 Guided Plug
        • Accurate and stable regulation with smooth closing

       

        • Requires low actuation pressure

       

        • Prevents diaphragm erosion and distortion

       

       

 

    • Internal “Differential Pressure Duct” Flow Sensor
        • No moving parts

       

        • Saves space and simplifies installation

       

       

 

Typical Applications

  • Computerized Irrigation Systems
  • Line Fill-Up Control
  • Pressure Reducing Systems
  • Multiple Independent Consumer Systems
  • Systems Subject to Varying Supply Pressure
  • Energy Saving Irrigation Systems
