Filter Backwash Hydraulic Valve

The BERMAD Filter Backwash Flow Control Valve is a hydraulically operated, diaphragm actuated control valve that limits filter system backwash flow to a constant preset maximum. This eliminates the risk of filtration element collapse or of grains being flushed out.
 

Features and Benefits

  • Line pressure driven Hydraulic Flow Control
    • Prevents flushing out of grains or filtration element collapse
  • Servo Flow Pilot Controlled
    • Dynamic integrated needle valve
    • Very low hysteresis
    • Easy flow setting
  • 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
  • Hydraulic Flow Sensor (upstream installation)
    • No moving parts
    • No need for flow straightening
       

Typical Applications

  • Filter Stations
  • Systems Subject to Varying Supply Pressure
