Filter Backwash Hydraulic Valve IR-170-beU

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.

Product Features & Benefits
