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.
 

Features and Benefits

  • Line Pressure Driven, Hydraulically Controlled
    • Prioritizes pressure zones
    • Controls system fill-up
    • Opens fully upon line pressure rise
  • Metal Control Accessories
    • Damage resistant
    • High pressure rating
  • 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
  • Simple In-Line Inspection and Service
     

Typical Applications

  • Line Fill-Up Control Solutions
  • Line Emptying Prevention
  • Infield Filters Backwash Pressure Sustaining
  • Systems Subject to Varying Supply Pressure
