Pressure Reducing Valve

The BERMAD Model IR-420-54-3Q-KX is an operated, diaphragm actuated control valve that accurately reduces higher upstream pressure to lower and stable preset downstream pressure. It is a Normally Closed valve that opens in response to a remote pressure drop command and shuts in the absence of that command. The BERMAD Model IR-420-54-3Q-b also serves as a Pressure Relief Valve protecting the system even when in closed position.

Features and Benefits

  • Normally Closed PRV with Relief Override Feature
    • Protects downstream and upstream systems
    • Closes upon control failure
    • Amplifies and relays weak remote command
  • 3-Way Pilot Controlled
    • Dynamic integrated needle valve
  • 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
  • Simple In-Line Inspection and Service

Typical Applications

  • Computerized Irrigation
  • Systems Subject to Varying Supply Pressure
  • Energy Saving Irrigation Systems
  • Remote and/or Elevated Plots
  • Multiple Control Valves Systems
