2" Double Check Valve for Non Potable Fire Protection

The 2" Double Check Valve for Non-Potable Fire Protection by Zurn Wilkins is engineered for commercial and industrial fire suppression systems utilizing non-potable water. Designed to prevent backflow contamination, this valve ensures fire protection systems meet stringent safety and regulatory standards without compromising water quality. Durable Construction: Made from ductile iron (ASTM A536) with 300-series stainless steel internals, providing long-lasting resistance to impact and corrosion in harsh environments. Advanced Sealing Technology: Features reversible, replaceable EPDM elastomer discs and precision-engineered thermoplastic check modules to maintain a tight seal against non-potable water chemistries. Compliance and Certification: UL Listed to UL 1436, FM Approved, and fully compliant with NFPA 13 and NFPA 25 standards, ensuring seamless integration with fire protection codes and inspections. Operational Pressure Support: Rated for pressures up to 175 PSI (12.1 bar) to reliably handle typical industrial and commercial fire system water pressures. Installation Flexibility: Compatible with standard 2-inch mechanical piping, including flanged and grooved ends, and suitable for both horizontal and vertical installation. Backflow Prevention: Effectively isolates non-potable water sources, such as reclaimed or industrial water, protecting potable water supplies from potential contamination. Maintenance Efficiency: Reversible, replaceable seats simplify on-site servicing, reducing downtime and ensuring quick restoration of fire system readiness. Low Pressure Drop Design: Minimizes pressure loss to maintain optimal system efficiency and quick fire pump response during emergencies. By incorporating the Zurn Wilkins 2" Double Check Valve into your fire protection infrastructure, you safeguard potable water sources while leveraging non-potable water for fire suppression. This valve’s robust and certified design minimizes maintenance needs and streamlines compliance, making it ideal for facility managers and fire protection contractors focusing on system reliability and regulatory adherence. Whether upgrading an existing system or installing a new one, it ensures contaminant-free water flow, preserves system pressure, and supports consistent fire protection performance.
