Pressure Reducing Valve IR-420-54-R

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

  • 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
