T-480 2" In-Line Check Valve For Backflow Prevention Systems

The Viking T-480 2" In-Line Check Valve delivers reliable one-way flow control to maintain backflow prevention and system integrity in fire suppression assemblies. Engineered for municipal, commercial, and industrial fire protection setups, this valve prevents backflow contamination that risks potable water safety and overall system reliability. It installs directly into fire protection water supply pipelines to ensure positive shut-off.

This component complies with NFPA 13 and NFPA 25 standards for fire protection system compatibility. It satisfies mandatory life safety codes by supporting routine testing, inspection, and maintenance requirements.

• ASTM A536 Ductile Iron Construction: Resists high tensile stress and environmental corrosion in rigorous fire protection environments.
• EPDM Elastomer Sealing: Creates a reversible, leak-proof seat that maintains backflow prevention under varying pressures.
• Stainless Steel Springs and Fasteners: Prevents premature component wear against continuous operational cycles and harsh elements.
• 175 PSI Pressure Rating: Handles maximum working pressures up to 12.1 bar (175 PSI) for standard fire protection conditions.
• Flexible Orientation: Installs securely into both horizontal and vertical pipeline configurations without performance loss.
• 2-Inch NPT Connections: Features female National Pipe Thread ends for straightforward integration into existing water supply lines.

Verify all local Authority Having Jurisdiction (AHJ) requirements and cross-reference system design pressures before commencing installation. Ensure proper alignment for pipeline orientation.
