Pressure Reducing and Sustaining Valve

The BERMAD Pressure Reducing and Sustaining Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve that performs three independent functions. The BERMAD Model IR-423-50-R sustains the preset minimum upstream pressure, reduces downstream pressure to a constant preset maximum, and it either opens or shuts in response to a remote pressure command.

Features and Benefits

  • Hydraulic Pressure Control
    • Line pressure driven
    • Sustains upstream line pressure
    • Controls system fill-up
    • Protects downstream systems
    • Hydraulically 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
  • Line Fill-Up Control
  • Line Enptying Prevention
  • Pressure Reducing Stations
  • Irrigation Machines
  • Distribution Centers
  • Low Supplied Pressure Irrigation Systems
