IR-172-54-bD

Flow Control and Pressure Reducing Valve

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.
 

Features and Benefits

  • 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
