Pressure Reducing Valve

The BERMAD Model IR-420-54-R is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. It is a Normally Closed valve, which opens in
response to a pressure rise command

Features and Benefits

  • Hydraulic Pressure Control Normally Closed
    • Line pressure driven
    • Closes upon control failure
    • Protects downstream systems
    • Amplifies and relays weak remote command
    • Hydraulically controlled On/Off
  • Advanced Globe Hydro-Efficient Design
    • Unobstructed flow path
    • Single moving part
    • High flow capacity
  • Fully Supported & Balanced Diaphragm
    • Requires low actuation pressure
    • Excellent low flow regulation performance
    • Progressively restrains valve closing
    • Prevents diaphragm distortion
  • User-Friendly Design
    • Easy pressure setting
    • Simple in-line inspection and service

Typical Applications

  • Computerized Irrigation
  • Pressure Reducing Stations
  • Remote and/or Elevated Systems
  • Irrigation Machines
  • Distribution Centers
  • Low Supplied Pressure Irrigation Systems
