Description

The Febco 850 Double Check Assembly Low Flow Device 1-1/4" is engineered to provide dependable backflow prevention in low flow fire protection and potable water systems, specifically designed for applications requiring compact size without sacrificing reliability. It is ideal for light hazard environments where space constraints and precision flow control are critical, such as sprinkler systems with low water demand and domestic water piping.

Technical Specifications

Main Body: Constructed from corrosion-resistant materials to withstand prolonged exposure to water and environmental conditions typical of residential and light commercial installations.
Internal Components: Equipped with stainless steel springs and high-grade elastomeric seals for durable function and minimal maintenance.
Check Valves: Dual check valves provide a redundant barrier to backflow, ensuring zero cross-contamination in line with industry standards.
Low Flow Design: Optimized for flow rates typical in residential fire protection and domestic water supply lines, reducing pressure loss while maintaining system integrity.

Regulatory Compliance

UL Listed: Meets UL 1469 standards for fire service water control valves, confirming its suitability for fire protection applications.
FM Approved: Factory Mutual certification certifies performance under fire protection system requirements.
ASSE 1015: Complies with ASSE standards specific to double check backflow preventers for potable water systems, ensuring safe operation in both fire and domestic settings.
AWWA C510: Adheres to American Water Works Association guidelines for backflow prevention device performance and durability.

Operational Compatibility

Working Pressure: Rated for a maximum operating pressure typically up to 175 PSI (12.1 bar), accommodating a wide range of municipal water supply conditions.
Connection Type: Available with NRS (Non-Rising Stem) globe or gate valve configurations to match existing fire protection and plumbing setups.
Installation Orientation: Supports both horizontal and vertical installations with upward flow, providing flexibility for space-restricted environments.
Temperature Range: Suitable for water temperatures ranging from 33°F to 140°F (0.5°C to 60°C), covering most indoor and outdoor scenarios.

The Febco 850 excels in preventing pollutants from entering potable water systems by utilizing two independent check valves, a critical feature in meeting stringent fire safety codes and water quality regulations. Its low flow certification makes it particularly effective in systems where water use is minimal but contamination risk remains high, such as residential sprinkler zones and certain commercial water lines. The compact 1-1/4" size facilitates installation in tight mechanical spaces or retrofit applications where larger assemblies would be impractical.

Practical considerations when installing the Febco 850 include ensuring compatibility with the existing piping end connections and verifying pressure ratings against system parameters. Maintenance is straightforward owing to reversible and replaceable internal seals, minimizing downtime during inspections or service intervals specified by NFPA 25.

For engineers and facility managers seeking an assembly that balances efficient low flow performance with regulatory compliance and long service life, the Febco 850 Double Check Assembly delivers a focused solution that minimizes risk while maintaining system functionality.
