IR-430-XZ

Pressure Sustaining Valve

The BERMAD Model IR-430-XZ Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that it sustains minimum preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure.
 

Features and Benefits

  • 3-Way Hydraulic Actuated Pressure Sustaining Valve
    • Controls system fill-up
    • Sustains upstream line pressure
    • Opens fully upon line pressure rise
    • Prioritizes pressure zones
  • 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
  • User Friendly Design
    • Easy pressure setting
    • Simple in-line inspection and service
       

Typical Applications

  • Downhill Supply Lines Emptying Prevention
  • Systems Subject to Varying Supply Pressure
  • Energy Saving Irrigation Systems
  • Pressure Zone Prioritizing
  • Line Fill-Up Control
  • Pump Overload and Cavitation Protection
