Pressure Sustaining Valve

The BERMAD Model IR-130-54-X is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of this command.

Features and Benefits

  • Line Pressure Driven, Hydraulically Normally Closed
    • Closes upon control failure
    • Prioritizes pressure zones and controls system fill-up
    • Opens fully upon line pressure rise
    • Amplifies and relays weak remote command
  • 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
    • Requires low actuation pressure
    • Prevents diaphragm erosion and distortion
  • Simple In-Line Inspection and Service

Typical Applications

  • Computerized Irrigation Systems
  • Remote and/or Elevated Plots
  • Line Fill-Up Control Solutions
  • Systems Subject to Varying Supply Pressure
  • Infield Filters Backwash Pressure Sustaining
  • Energy Saving Irrigation Systems
