Description

Technical Specifications (Material Focus)

  • Main Body: Manufactured from ductile iron with fusion-bonded epoxy coating conforming to ASTM A536, ensuring corrosion resistance and durability in residential installation environments.
  • Valves and Stem: Equipped with an Outside Stem and Yoke (OS&Y) gate valve constructed with carbon steel stem and high-grade ductile iron yoke housing, providing precise flow control and ease of operation.
  • Internal Components: Stainless steel springs and fasteners in 300-series grade for reliable long-term mechanical integrity.
  • Sealing Elements: EPDM elastomer sealing discs are reversible and replaceable, ensuring a positive seal and resistance to common water additives and temperature variability.
  • Flow Configuration: Unique Z pattern design improves hydraulic efficiency by reducing pressure loss and optimizing water flow path within the assembly.

Regulatory Compliance

  • UL Listed: Certified to UL 312 for Reduced Pressure Principle Backflow Preventers, confirming performance under residential fire protection scenarios.
  • FM Approved: Approved by Factory Mutual, attesting to compliance with fire protection equipment standards.
  • ASSE Standard: Meets ASSE 1013 requirements for reduced pressure backflow preventers, ensuring protection against contamination of potable water supplies.
  • NFPA Compliance: Designed to comply with NFPA 13 and NFPA 25 standards governing installation, inspection, and maintenance of sprinkler systems and backflow assemblies.

Operational Compatibility

  • Pressure Rating: Rated for maximum working pressure of 175 PSI (12.1 bar), suitable for typical residential fire protection water systems.
  • Temperature Range: Operates effectively between 33°F and 140°F (0.5°C to 60°C), aligning with standard residential water supply conditions.
  • Connection Types: Compatible with ANSI B16.1 flanged connections, enabling secure installation in existing piping networks within residential mechanical rooms or underground vaults.
  • Installation Position: Suitable for horizontal or vertical piping, with flow orientation maintained as per manufacturer guidance for optimal valve function.

The 8" Reduced Pressure Assembly Z Pattern with OS&Y valve is engineered to prevent backflow contamination while providing dependable fire protection in residential settings. Its robust ductile iron body with epoxy coating stands up to environmental stressors typically encountered in domestic water systems, and the OS&Y valve offers straightforward manual isolation and maintenance access, reducing downtime during inspection cycles.

This assembly's Z pattern design minimizes pressure drop, ensuring faster response during fire emergencies where water flow must be maximized. The inclusion of reversible EPDM seats allows for extended service life, minimizing maintenance interventions and ensuring consistent sealing under varied temperature and water quality conditions.

Ideal for residential property managers, fire protection contractors, and system installers, this assembly addresses critical concerns such as contamination prevention and code compliance while facilitating routine testing required by NFPA guidelines. Its construction and certifications provide confidence in its durability and regulatory acceptance, critical for systems protecting occupant safety.

When compared to traditional backflow assemblies without OS&Y valves, this model offers enhanced operational control and longer lifecycle due to superior materials and design. The incorporation of tested and approved components ensures alignment with industry standards and facilitates easier integration within complex residential fire safety systems.
