Flow Control and Pressure Reducing Valve

The BERMAD Model IR-172-55-bD is a hydraulically operated, diaphragm actuated control valve that performs three independent functions. It limits system demand to a preset maximum flow rate; it reduces downstream pressure to maintain a constant preset maximum, and it either opens
or shuts in response to an electric signal.

Features and Benefits

  • Line Pressure Driven, Electrically Controlled On/Off
    • Limits fill-up rate and consumer over-demand
    • Protects downstream system
    • Easy flow and pressure setting
  • 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 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
  • Remote and/or Elevated Plots
  • Line Fill-Up Control
  • Multiple Independent Consumer Systems
  • Pressure Reducing Stations
  • Distribution Centers
  • Filter Stations
