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
