Filter Backwash Hydraulic Valve IR-470-beKU

Filter Backwash Hydraulic Valve IR-470-beKU

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
