Product Overview


Ductile Iron PN16 DF41X Reverse Flow Preventer Backflow preventer valve
DF41X backflow preventeris a hydraulic control combination device that strictly limits the water flow in the pipeline to only one
way. Its main purpose is to prevent the media backflow in the pipeline under any working conditions, so as to avoid backflow
pollution.










Body
DF41X backflow preventer adopts two-stage check system, and adds a drainage pressure relief device. This design prevents backflow
contamination even if the secondary check seal is broken at the same time









Flange holes
Every flange hole is carefully polished, smooth and burr-free.
It is widely used in tap water supply equipment, especially when the backflow pollution of drinking water pipeline is serious and
there is no effective device to prevent backflow pollution.
