Flow Control and Pressure Reducing Valve IR-472-54-bKU

The BERMAD Model IR-472-54-bKU is a hydraulically operated, diaphragm actuated control valve that limits demand and reduces downstream pressure to constant preset maximum values. It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.

  • Line pressure driven, Normally Closed

-Closes upon control failure

-Limits fill-up rate and consumer over-demand

-Protects downstream system

-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 flow regulation performance

-Progressively restrains valve closing

-Prevents diaphragm distortion

  • Hydraulic Flow Sensor (upstream installation)

-No moving parts

-No need for flow straightening

  • Simple In-Line Inspection and Service.

Typical Applications

  • Computerized Irrigation Systems
  • Remote and/or Elevated Plots
  • Multiple Independent Consumer Systems
  • Line Fill-Up Control Solutions
  • Pressure Reducing Systems
  • Distribution Centers
