6" Reduced Pressure Backflow Preventor Valve Ductile Iron Coated

The 6" Reduced Pressure Backflow Preventor Valve Ductile Iron Coated functions as a specialized backflow prevention assembly engineered for critical commercial and institutional fire protection systems. Installed inline to safeguard potable water supplies from contamination, this unit utilizes an N Pattern continuous backflow detection differential pressure mechanism to alert operators early to potential leaks. It satisfies the strict compliance mandates of NFPA 13 for fire sprinkler installations and NFPA 25 for ongoing inspection, testing, and maintenance of water-based fire protection systems.

Designed for installation in mechanical rooms and confined spaces, this assembly handles environments subject to pipe vibration and thermal expansion. It accommodates both horizontal and vertical upward flow orientations, while its grooved butterfly design significantly reduces installation labor and maintenance downtime compared to traditional flanged alternatives.

• Main Body Material: Ductile iron with a fusion-bonded epoxy coating resists corrosion and mechanical wear to extend the valve lifespan in challenging environments.
• Internal Components: 300-series stainless steel springs and fasteners ensure long-term durability and consistent operation under demanding conditions.
• Valve Mechanism: N Pattern Reduced Pressure Detector Valve features a grooved butterfly mechanism for precise flow management and rapid response to pressure variations.
• Seats and Seals: High-grade elastomeric materials compatible with potable water provide a leak-tight shutoff across variable operating conditions.
• Grooved Ends: Built per AWWA C606 standards for grooved mechanical joints, enabling secure, vibration-resistant connections for new installations and retrofits.
