Pressure Sustaining Valve

The BERMAD Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. It either opens or shuts in response to a remote pressure command.
 

Features and Benefits

  • Line Pressure Driven, Hydraulically Controlled On/Off
    • Prioritizes pressure zones
    • Controls system fill-up
    • Opens fully upon line pressure rise
  • 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
  • Line Fill-Up Control Solutions
  • Line Emptying Prevention
