3" Double Check Detector Backflow Preventor Valve with OSY Valve by Manufacturer

The 3" Double Check Detector Backflow Preventor Valve with OSY Valve is designed for commercial fire protection and plumbing systems requiring precise water flow control and contamination prevention. Combining robust construction with regulatory compliance, this valve assembly is ideal for facilities needing reliable backflow detection and isolation in fire line applications.

• Material Construction: Crafted from ductile iron (ASTM A536) with a corrosion-resistant coating, featuring 300-series stainless steel springs and fasteners for enhanced durability.
• Backflow Prevention Design: Tandem double check detector configuration with reversible EPDM elastomer seats and engineered thermoplastic check modules for superior sealing and wear resistance.
• OS&Y Valve Integration: Outside Screw & Yoke valve provides clear visual indication of valve position, enabling straightforward monitoring, shutoff, and maintenance in fire protection systems.
• Regulatory Certifications: UL Listed (UL 1469) and FM Approved for fire service applications, meeting ASSE 1015 and AWWA C510 standards, ensuring compliance with health and municipal code requirements.
• Operational Pressure & Orientation: Rated for continuous operation up to 175 PSI (12.1 bar) with support for both horizontal and vertical installations, optimized for upward flow to prevent water stagnation.
• Connection Flexibility: Available with ANSI B16.1 flanged ends and AWWA C606 grooved ends, allowing integration into diverse mechanical rooms and underground piping setups.
• Maintenance-Friendly Features: Reversible check discs and OS&Y valve simplify inspection and servicing, reducing downtime during mandatory quarterly and annual fire system evaluations.

This backflow preventer valve ensures critical protection of potable water supplies by preventing contaminated water from back siphoning into municipal or building water systems. It reliably detects unauthorized water usage or leaks in fire sprinkler and standpipe lines, enhancing safety and regulatory compliance for commercial and industrial sites. The rugged ductile iron construction with corrosion-resistant components supports long-term performance even in harsh environments, reducing replacement frequency and operational disruptions. Its adaptable connection options and installation orientations provide versatility in retrofits and new installations alike, helping facility managers maintain water integrity while simplifying maintenance routines.
