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.

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
