The 2-1/2" Reduced Pressure Detector Z Pattern Butterfly Valve is a specialized backflow preventor designed for residential fire protection systems. It combines efficient flow control with continuous backflow monitoring, delivering crucial early detection to protect potable water supplies from contamination.

• Reliable Materials: Constructed with a heavy-duty ductile iron body coated in fusion-bonded epoxy for superior corrosion resistance, plus a precision-machined stainless steel or aluminum bronze disc that ensures durability even in aggressive flow environments.
• Advanced Detection Assembly: Features an integrated differential pressure sensor that actively monitors the reduced pressure zone, providing instant alerts to potential backflow events before contamination risks escalate.
• Z Pattern Design: Allows flexible installation both horizontally and vertically within residential fire sprinkler piping, optimizing space and simplifying system layout.
• Grooved End Connections: Engineered according to AWWA C606 standards for quick, secure installation, reducing labor time compared to traditional flanged or threaded fittings.
• Compliance and Safety: UL Listed to UL 312, FM Approved, and fully compliant with NFPA 13 and NFPA 25 standards, ensuring regulatory adherence and peace of mind for fire protection professionals and homeowners.
• Pressure and Temperature Ratings: Supports pressures up to 175 PSI (12.1 bar) and operates effectively between 33°F and 140°F (0.5°C to 60°C), accommodating typical residential water system conditions.
• Durable Sealing: Equipped with chemically resistant Nitrile (NBR) or EPDM elastomer seals to maintain leak-tight performance across temperature variations commonly found in residential settings.

This valve addresses the critical challenge of safeguarding potable water in residential fire systems by combining robust flow control with reliable backflow detection. Its integrated differential pressure sensor offers continuous monitoring, enabling early identification of backflow risks and helping to maintain code-compliant performance for NFPA inspections. Thanks to grooved connections and a compact Z pattern layout, installation and retrofits are more efficient without compromising system integrity. For plumbing professionals and fire system designers, this backflow preventor provides a dependable solution that ensures water safety while enhancing system reliability and ease of maintenance.
