The 3" Double Check Detector Backflow Preventor Valve Grooved Assembly by N Pat is engineered for plumbing professionals, fire protection engineers, and facility managers seeking reliable protection against water contamination in fire suppression and potable water systems. This valve combines robust materials with advanced detection capabilities, streamlining installation and enhancing system safety through proactive backflow monitoring.

• Durable Construction: Precision-fabricated from fusion-bonded epoxy-coated ductile iron (ASTM A536), providing superior corrosion resistance and strength for both mechanical and underground installations.
• Corrosion-Resistant Internal Components: Features 300-series stainless steel springs and fasteners designed to endure harsh fire protection environments without compromising durability.
• Advanced Check Modules: Made from glass-filled Noryl™ thermoplastic for dependable valve operation and resistance to mechanical wear over time.
• Reversible EPDM Seats: Replaceable elastomer discs provide a reliable, positive seal that prevents backflow contamination effectively.
• Patgrooved Butterfly End Connections: Specifically designed for compatibility with 3" grooved piping systems, reducing installation time and simplifying maintenance compared to traditional flanged systems.
• Certified Compliance: UL 1469 listing and FM approval ensure this valve meets stringent fire protection standards; ASSE 1015 and AWWA C510 compliance guarantee effective backflow prevention and durability.
• NFPA-Ready: Supports NFPA 13 and NFPA 25 requirements, including integrated test cocks for differential pressure testing vital in sprinkler system inspections.
• Operating Parameters: Rated for pressures up to 175 PSI (12.1 bar) and temperatures from 33°F to 140°F (0.5°C to 60°C), adaptable to a broad range of commercial and industrial conditions.
• Flexible Installation: Suitable for both horizontal and vertical (upflow) configurations ensuring compatibility with diverse piping layouts.
• Proactive Backflow Detection: The integrated double-check detector mechanism provides early warning of backflow conditions, allowing timely maintenance before contamination affects potable water safety.

This backflow preventor valve protects potable water supplies by actively monitoring and preventing reverse flow, a critical feature in fire sprinkler and industrial water systems vulnerable to pressure changes. Its grooved butterfly end connections simplify installation and reduce downtime, while regulatory compliance certifications reassure professionals that the valve meets industry safety standards. Ideal for facilities requiring reliable backflow prevention combined with efficient detection capabilities, it offers peace of mind in safeguarding water quality and meeting fire code requirements. Whether used in new installations or system upgrades, this assembly addresses the complexities of preventing cross-contamination with durable materials and integrated monitoring.
