Pressure Reducing Valve IR-420-54-KX

Pressure Reducing Valve IR-420-54-KX

The BERMAD Normally Closed, Pressure Reducing Valve with Hydraulic Control, is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand, and opens fully upon line pressure drop. It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.

  • Hydraulic Pressure Control, Normally Closed

-Line pressure driven

-Closes upon control failure

-Protects downstream systems

-Opens fully upon line pressure drop

-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

  • User-Friendly Design

-Easy pressure setting

-Simple in-line inspection and service

Typical Applications

  • Computerized Irrigation
  • Pressure Reducing Stations
  • Systems Subject to Varying Supply Pressure
  • Rimote and/or Elevated Plots
  • Distribution Centers
