The 2-1/2" Double Check Detector Backflow Preventor Valve Assembly is meticulously engineered for fire protection systems and plumbing networks requiring stringent backflow prevention. Designed for professionals such as fire protection contractors, water authorities, and facility managers, it ensures water quality by preventing contaminants from entering potable water supplies.

• Robust Construction: Body made from ASTM A536 ductile iron for durability in mechanical rooms and outdoor installations, with 300-series stainless steel internal parts to resist corrosion.
• Reliable Sealing Mechanism: Dual check valves use reversible, replaceable high-strength glass-filled thermoplastic modules paired with EPDM elastomer seats, delivering effective and long-lasting backflow prevention.
• Integrated OS&Y Gate Valve: Outside Screw & Yoke valve offers positive shutoff with clear visual status indication for easy operation and maintenance.
• Y-Strainer Included: Protects the valve assembly by filtering debris, ensuring uninterrupted flow and reducing maintenance needs.
• Regulatory Compliance: Certified under UL 312, FM Approval, ASSE Standard 1015, and supports NFPA 13 and NFPA 25 requirements, making it suitable for stringent fire protection code adherence.
• Operational Range: Handles working pressures up to 175 PSI (12.1 bar), compatible with most municipal and industrial fire protection water systems.
• Installation Flexibility: Equipped with grooved ends conforming to AWWA C606 for quick and secure connections; supports both horizontal and vertical orientations for various layout needs.

This backflow preventor assembly enhances system reliability by detecting and preventing unauthorized reverse flow, a critical safeguard in fire suppression infrastructure. Its replaceable internal seats and modular components simplify maintenance and reduce downtime. The inclusion of the Y-strainer and OS&Y valve ensures debris management and straightforward valve operation, crucial for compliance inspections and functional testing. Its compatibility with common grooved coupling systems accelerates installation and retrofit projects, providing an efficient solution for maintaining potable water integrity in environments vulnerable to contamination. Ideal for professionals overseeing fire sprinkler systems and municipal water protection, this assembly integrates detection, shutoff, and filtration in one robust, code-compliant unit.
