Colt Series RPZA Backflow Preventer

The Colt Series RPZA Backflow Preventer 2" is a reliable solution designed for potable water systems and fire protection applications, engineered to protect water supplies from hazardous contamination. It is an essential component for fire protection professionals, facility managers, and plumbing engineers seeking durable, code-compliant backflow prevention in commercial and industrial settings.

• Robust Construction: Crafted from high-grade ductile iron with a fusion-bonded epoxy coating, the body resists corrosion and wear, ensuring longevity in demanding environments.
• Corrosion-Resistant Components: Internals use 300-series stainless steel springs and fasteners to maintain strength and durability under variable pressure and temperature conditions.
• Advanced Check Valve System: Incorporates glass-filled thermoplastic check valves with replaceable EPDM elastomer seats for a secure, leak-proof seal against backflow.
• Certified Compliance: UL Listed (UL 151), FM Approved, and ASSE 1013 certified, meeting rigorous safety and performance standards for both potable water and fire protection systems.
• Versatile Installation: Designed for up to 175 PSI working pressure, ANSI B16.1 flanged connections, and suitable for both horizontal and vertical configurations.
• Wide Temperature Range: Operates effectively between 33°F and 140°F (0.5°C to 60°C), accommodating typical indoor mechanical rooms and underground vaults.
• Maintenance-Friendly Design: Equipped with replaceable seat discs and pre-drilled test cocks to simplify inspection, testing, and maintenance per NFPA 13 and 25 standards.

By preventing hazardous backflow, the Colt Series RPZA Backflow Preventer safeguards drinking water quality, particularly within fire sprinkler and service line systems exposed to variable pressures. Its reduced pressure zone design provides enhanced protection over traditional double check valves, making it ideal for environments where contamination risk is high. Easy to integrate into existing infrastructure, it supports compliance with fire protection codes and water safety regulations, reducing downtime and maintenance complexity. This backflow preventer is a practical choice for commercial, industrial, and institutional facilities prioritizing water safety and system reliability.
