Febco 850 Double Check Assembly Low Flow Device 1-1/4"

The Febco 850 Double Check Assembly Low Flow Device 1-1/4" is a specialized backflow preventer designed for low flow fire protection and potable water systems. Its compact size and reliable dual check valves make it an ideal choice for residential and light commercial applications where space is limited and precise flow control is essential.

• Compact Design: Engineered for tight spaces, the 1-1/4" size fits easily into residential sprinkler systems and domestic water lines without compromising performance.
• Corrosion-Resistant Materials: Main body is constructed from durable, corrosion-resistant components to ensure longevity in typical indoor and outdoor plumbing environments.
• Dual Check Valves with Stainless Steel Springs: Provides two layers of backflow protection, reducing the risk of cross-contamination and ensuring compliance with stringent safety standards.
• Low Flow Optimization: Specifically calibrated to maintain system integrity with minimal pressure loss in low water demand scenarios commonly found in light hazard fire protection and potable water lines.
• Regulatory Approvals: UL Listed to UL 1469, FM Approved, ASSE 1015 compliant, and aligned with AWWA C510 standards, confirming its reliability for both fire protection and drinking water safety.
• Flexible Installation: Compatible with both horizontal and vertical (upward flow) setups, and offers NRS globe or gate valve connection options for easy integration into existing systems.
• Durable Sealing: Incorporates high-grade elastomeric seals that minimize maintenance needs while ensuring a tight, leak-free operation across a wide temperature range (33°F to 140°F).
• Pressure Rating: Rated for up to 175 PSI, accommodating most municipal water supply pressures encountered in residential and commercial settings.

This device safeguards drinking water by preventing contaminants from flowing backward into potable systems, particularly critical in fire protection zones with low water usage. Its compact footprint makes it the go-to solution for retrofits and installations where larger assemblies won’t fit. Ideal for homeowners, plumbers, and fire protection professionals, the Febco 850 ensures peace of mind by combining robust construction and precise flow control in one reliable backflow prevention solution.
