Pressure Reducing and Sustaining Valve IR-423-55-R

The BERMAD Pressure Reducing and Sustaining Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that performs three independent functions. The BERMAD Model IR-423-55-R sustains the preset minimum upstream pressure, reduces downstream pressure to a constant preset maximum, and it either opens or shuts in response to an electric signal.

  • Hydraulic Pressure Control with Solenoid Control

-Line pressure driven

-Sustains upstream line pressure

-Controls system fill-up

-Protects downstream systems

-Electrically controlled On/Off

  • Advanced Globe Hydro-Efficient Design

-Unobstructed flow path

-Single moving part

-High flow capacity

  • Fully Supported & Balanced Diaphragm

-Requires low opening and actuation pressure

-Excellent low flow regulation performance

-Progressively restrains valve closing

-Prevents diaphragm distortion

  • Simple In-Line Inspection and Service

Typical Applications

  • Computerized Irrigation
  • Remote and/or Elevated Plots
  • Pressure Zone Prioritizing
  • Line Fill-Up Control
  • Line Emptying Prevention
  • Pressure Reducing Stations
