4 In SS Reduced Pressure Zone Backflow Preventer Assembly, NRS Shutoffs, Cam-Check Valves, Fire Flow Switch Checks

This 4 inch reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance. This assembly consists of a short lay length lightweight stainless steel body, seated gate valves with non-rising stem, test cocks, flow switch, corrosive resistant stainless steel bottom mounted relief valve, and a patented cam-check assembly.
