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 filter 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
  • Engineered Plastic Valve with Industrial Grade Design
    • Highly durable, chemical and cavitation resistant
    • No internal bolts and nuts
  • hYflow ‘Y’ Valve Body with “Look Through” Design
    • Ultra-high flow capacity – Low pressure loss
  • Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug
    • Accurate and stable regulation with smooth closing
    • Requires low actuation pressure
    • Prevents diaphragm erosion and distortion
  • Hydraulic Flow Sensor (upstream installation)
    • No moving parts
    • No need for flow straightening
       

Typical Applications

  • Filter Stations
  • Systems Subject to Varying Supply Pressure
