The 8 Febco 850 Double Check OS&Y Backflow Prevention System is designed for fire protection and commercial plumbing professionals seeking reliable prevention of contaminant backflow into potable water supplies. Engineered to meet stringent regulatory standards, this assembly ensures water safety in fire sprinkler and standpipe systems with durable construction and clear operational feedback.

  • Corrosion-Resistant Construction: Manufactured from fusion-bonded epoxy-coated ductile iron compliant with ASTM A536, it withstands harsh environments common in fire service setups.
  • Durable Internal Components: Utilizes 300-series stainless steel springs and fasteners for mechanical strength and extended service life under cyclic pressures.
  • Reliable Check Modules: Features glass-filled Noryl™ thermoplastic check components resistant to chemical degradation and dimensional changes, ensuring consistent performance.
  • Effective Sealing: Reversible and replaceable EPDM elastomer discs maintain a positive seal to prevent backflow and minimize pressure loss.
  • Regulatory Compliance: UL 1469 Listed, FM Approved, and conforms to ASSE 1015, AWWA C510 standards, supporting NFPA 13 and NFPA 25 fire protection codes.
  • High Pressure Rating: Rated for working pressures up to 175 PSI (12.1 bar), suitable for both fire service and non-health hazard potable water applications.
  • OS&Y Valve Design: Outside Stem & Yoke provides clear valve position indication, simplifying routine inspections and maintenance.
  • Versatile Installation: Compatible with ANSI B16.1 flanged and AWWA C606 grooved end connections; supports horizontal and vertical upward flow configurations.
  • Pre-Drilled Test Cocks: Facilitates easy and accurate system testing to ensure ongoing compliance and operational integrity.

This backflow prevention system protects municipal water supplies by preventing reverse flow contamination in commercial fire protection setups. It is ideal for fire sprinkler lines, standpipe systems, and fire pump connections where maintaining water purity is critical. Its corrosion-resistant design and high-strength components reduce maintenance frequency and extend operational lifespan, addressing common concerns in demanding fire service environments. The clear OS&Y valve position indicator simplifies compliance inspections under NFPA standards, while versatile end connections enable straightforward integration into a wide range of piping systems. Whether installed in mechanical rooms or underground vaults, this system delivers dependable backflow prevention aligned with industry safety and regulatory requirements.
