Watts Reduced Pressure Zone Assemblies, Bronze 0062841

The Watts Series 919 Reduced Pressure Zone Assembly, part number 0062841, is designed to protect potable water supplies from contamination due to backflow caused by backsiphonage or backpressure. This assembly features a bronze body construction, two poppet-style check valves, and a replaceable intermediate relief valve. It is available in sizes ranging from 1/4" to 2" (5mm to 50mm) and is suitable for health hazard applications. The assembly includes separate access covers for the check valves and relief valve, allowing for easy maintenance. All rubber elastomers are made from chloramine-resistant materials, and the check valve poppet assemblies are guided by a corrosion-resistant plastic guide. The design incorporates push-in type check valve and relief valve seats, which eliminate threads from the waterway, and a bottom-mounted relief valve that reduces installation clearances. The maximum working pressure for this assembly is 175 psi (12.1 bar), and it operates effectively within a temperature range of 33¬?F to 180¬?F (0.5¬?C to 82¬?C). It is equipped with top-mounted test cocks for ease of testing and is standardly furnished with NPT body connections. This assembly is ideal for installations requiring compliance with national plumbing codes and local water authority requirements.
