The Flanged Swing Check Valve is a precision-engineered solution designed for fire protection and plumbing professionals who need reliable backflow prevention in commercial and industrial fire sprinkler systems. Its robust construction and seamless integration make it a trusted component that supports stringent fire safety standards.

• Durable Material: Constructed from ASTM A536 precision-cast ductile iron, offering exceptional tensile strength and corrosion resistance suited for demanding fire protection environments.
• Protective Coating: Fusion-bonded epoxy finish provides enhanced defense against moisture and chemicals common in fire suppression systems, extending the valve’s lifespan.
• Reliable Internal Components: Features stainless steel hinge pins and bearings designed to withstand repeated mechanical use without degradation, ensuring consistent operation.
• Efficient Swing Check Mechanism: Elastomer-seated disc guarantees positive shut-off to prevent backflow, while minimizing water hammer effects to protect piping integrity.
• Compliance and Certification: UL Listed (UL 312), FM Approved, and compliant with NFPA 13 and 25 standards, meeting rigorous fire code requirements for safety and performance.
• Pressure and Temperature Range: Operates reliably up to 175 PSI (12.1 bar) and within temperatures from 33°F to 140°F (0.5°C to 60°C), suitable for typical fire sprinkler conditions.
• Installation Compatibility: Flanged ANSI B16.1 ends facilitate secure installation in standard piping systems, designed primarily for horizontal placement with adaptability to upward vertical flow.

This valve effectively solves common issues in backflow prevention by maintaining system integrity with minimal pressure drop and eliminating reverse flow risks. Its combination of ductile iron body and stainless steel internals offers superior resistance to corrosion and wear, significantly reducing maintenance demands and prolonging service life. Ideal for commercial and industrial fire protection systems, it ensures compliance with safety regulations while simplifying retrofit installations. Choosing the Flanged Swing Check Valve means securing dependable backflow prevention, enhancing operational efficiency, and meeting the strict demands of fire protection networks.
