The 8" Double Check Detector Backflow Preventer Valve, crafted from durable ductile iron meeting ASTM A536 standards, is designed for professionals seeking reliable protection in fire protection and potable water systems. Its robust construction combined with advanced components ensures consistent prevention of water contamination caused by backflow.

• Material Quality: The main body uses ASTM A536 ductile iron for enhanced strength and impact resistance, ideal for demanding industrial and municipal installations.
• Advanced Valve Design: Features a grooved butterfly valve with a gasketed seal to ensure secure isolation without halting backflow prevention, easing maintenance tasks.
• Corrosion-Resistant Internal Components: Springs and fasteners are made of 300-series stainless steel, extending the valve’s lifespan even in corrosive environments.
• Durable Check Valve Modules: Dual check valves utilize high-strength glass-filled Noryl™ thermoplastic to withstand cyclic pressures commonly present in fire sprinkler systems.
• Replaceable, Reliable Sealing: EPDM elastomer seats provide reversible and replaceable sealing surfaces for consistent shutoff and operational testing accuracy.
• Regulatory Compliance: Certified to UL 1469 and FM approved for fire protection, plus meets ASSE 1015, AWWA C510, and NFPA 13/25 standards for comprehensive industry acceptance.
• Operational Specification: Supports pressures up to 175 PSI and operates within 33°F to 140°F, suitable for commercial and residential fire protection and water supply systems.
• Installation Flexibility: Compatible with AWWA C606 grooved piping for quick, secure connections and adaptable to horizontal or vertical upward flow configurations.

This backflow preventer uniquely combines a double check valve assembly with a detector function, enabling continuous monitoring of water flow and early identification of potential backflow issues before contamination occurs. By integrating a grooved butterfly valve, it allows maintenance without system downtime, a critical advantage in fire protection systems. Designed for fire sprinklers, municipal water systems, and commercial buildings, it provides peace of mind through proven compliance with stringent safety standards. This valve addresses common challenges such as installation time, system downtime, and regulatory requirements, ensuring efficient protection against backflow contamination while simplifying routine inspections and maintenance.
