LF850-NRS DC 10

This 10 inch lead free MasterSeries (R) in-line design double check valve backflow preventer assembly is designed for non-health hazard applications and prevents the backflow of pollutants that are objectionable but not toxic, from entering into the potable water supply due to backsiphonage and or backpressure. It is ideal for protection of non-health hazard cross-connections or for containment at the service line entrance. This assembly consists of an epoxy coated ductile iron body using ArmorTek coating technology for advanced corrosion resistance, flanged end connections, two in-line independent check valves, replaceable stainless steel check seats, test cocks, and non-rising stem resilient wedge gate valves. Check with local water authorities for non-health application requirements. The maximum working pressure is 175 psi (12.06 bar).
