Description

Technical Specifications (Material Focus)

  • Main Body: Constructed from ASTM A536 grade ductile iron, providing enhanced strength and resistance to impact in fire protection environments.
  • Internal Components: Manufactured using 300-series stainless steel, including stems, discs, and fasteners to resist corrosion and maintain mechanical integrity under high moisture and pressure.
  • Valve Type: Outside Stem and Yoke (OS&Y) valve system enables visual confirmation of valve position and facilitates adjustments or maintenance without interrupting system operation.

Regulatory Compliance

  • UL Listing: Certified under UL 312 standard for backflow prevention devices in fire protection systems, verifying reliable shutoff and contamination prevention.
  • FM Approval: Endorsed by Factory Mutual for fire suppression system applications, confirming performance under rigorous fire protection industry standards.
  • NFPA Compliance: Meets requirements of NFPA 13 (Installation of Sprinkler Systems) and NFPA 14 (Standpipe and Hose Systems), ensuring full regulatory alignment for fire safety systems involving backflow prevention.

Operational Compatibility

  • Pressure Rating: Engineered to operate reliably at pressures consistent with typical fire suppression system demands, supporting operational integrity across varying flow conditions.
  • Connection Size and Type: Standard 10-inch connection diameter tailored for large commercial and industrial piping, compatible with both wet and dry pipe system configurations.
  • Installation Flexibility: Designed for integration in horizontal or vertical piping arrangements, supporting versatile deployment across diverse fire protection layouts.

This 10" 3000SS OS&Y Backflow Preventer addresses critical concerns in fire protection systems by effectively preventing backflow contamination between fire service water lines and potable or non-potable supplies. The selection of ductile iron and stainless steel components ensures structural reliability and corrosion resistance essential in both subterranean and mechanical room installations. The OS&Y valve mechanism provides maintenance personnel with straightforward operational visibility and access, reducing downtime during inspections or valve actuations.

Ideal for use in commercial buildings, industrial complexes, and municipal fire protection infrastructures, this backflow preventer supports compliance with strict fire safety protocols while safeguarding water quality against pollutants introduced via pressure fluctuations or backpressure. Its compatibility with both wet and dry sprinkler or standpipe systems makes it applicable in a wide range of firefighting water delivery scenarios.

The UL and FM listed certifications combined with adherence to NFPA 13 and NFPA 14 standards offer assurance that the device fulfills critical performance benchmarks. This device is engineered not only to protect water supplies from contamination but also to maintain uninterrupted fire system readiness, supporting automatic and manual fire suppression interventions without compromising safety or regulatory adherence.

Maintenance teams benefit from the OS&Y design by gaining visual confirmation of valve status—open or closed—during routine inspections or emergency operations, enabling quicker response and verification. The material durability reduces lifecycle costs by limiting the need for frequent part replacements or corrosion mitigation measures.

When selecting a backflow preventer for large-diameter fire protection systems requiring dependable contamination control, the 10" 3000SS OS&Y Backflow Preventer offers a solution aligned with industry standards, engineered resilience, and operational efficiency customized for demanding commercial and industrial applications.
