Pressure Reducing Valve IR-420-54-bK

Pressure Reducing Valve IR-420-54-bK

The BERMAD Model IR-420-54-bK is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand or varying upstream pressure. It is a Normally Closed valve, which opens in response to a remote pressure drop command and shuts in the absence of that command.

  • Line Pressure Driven Normally Closed PRV

-Protects downstream systems

-Closes upon control failure

-Amplifies and relays weak remote command

  • Pressure Reducing Servo Pilot Controlled

-Dynamic integrated needle valve

-Settable to 0.5 bar; 7 psi

-Very low hysteresis

  • 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 System
  • Drip-Tape Systems
  • Low Set Pressure Applications
  • Remote and/or Elevated Plots
  • Distribution Centers
