IR-430-54-KX

Pressure Sustaining Valve

The BERMAD Model IR-430-54-KX 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 that command.
 

Features and Benefits

  • Line Pressure Driven, Hydraulically Normally Closed
    • Closes upon control failure
    • Prioritizes pressure zones & controls system fill-up
    • Opens fully upon line pressure rise
    • Amplifies and relays weak remote command
  • Advanced Globe Hydro-Efficient Design
    • Unobstructed flow path
    • Single moving part
    • High flow capacity
  • Fully Supported & Balanced Diaphragm
    • Requires low actuation pressure
    • Excellent low regulation performances
    • Progressively restrains valve closing
    • Prevents diaphragm distortion
  • User-Friendly Design
    • Easy pressure setting
    • Simple in-line inspection and service
       

Typical Applications

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