Zurn Wilkins DCV Fire Protection Double Check Valve

The Zurn Wilkins DCV Double Check Valve for Fire Protection is a professional-grade backflow prevention solution engineered to safeguard potable water supplies from contamination within fire suppression systems. This valve is designed for fire safety professionals, contractors, and facility managers, ensuring reliable water supply protection while simplifying installation and maintenance by eliminating the need for a traditional Outside Stem and Yoke (OS&Y) valve.

• Superior Backflow Prevention: Features a dependable double check design with two independently operating check valves that effectively blocks reverse flow, preventing cross-connection hazards and maintaining water purity in accordance with strict plumbing codes.
• Durable Construction: Built with a fusion-bonded epoxy-coated ductile iron body (ASTM A536) and 300-series stainless steel springs and fasteners to provide outstanding corrosion resistance and long-term durability under fire system conditions.
• Advanced Internal Components: Equipped with high-strength, glass-filled thermoplastic check modules and reversible, replaceable EPDM elastomer discs that ensure a secure seal across varying pressures.
• Streamlined OS&Y-Free Design: The absence of an external stem and yoke reduces the overall footprint and complexity, making it an ideal choice for tight mechanical rooms and underground setups where space is limited.
• Certified Compliance: Meets rigorous industry standards for fire service protection, including UL 1469 listing, FM approval, ASSE 1015 certification, and compliance with NFPA and AWWA C510 standards.
• Operational Efficiency: Supports continuous working pressure up to 175 PSI and functions effectively in temperatures ranging from 33°F to 140°F, ensuring consistent performance during critical emergencies.
• Versatile Installation: Designed for fast, straightforward integration into standard fire protection piping, supporting both horizontal and vertical upward flow orientations to fit diverse system layouts.

This Zurn Wilkins Double Check Valve is essential for maintaining the integrity of fire sprinkler and standpipe systems by preventing contaminated water from flowing back into the public water supply. By combining robust materials with a compact, efficient design, it minimizes maintenance demands and potential leak points while ensuring regulatory compliance. Whether for new construction or retrofitting existing infrastructure, this double check valve delivers the reliability and peace of mind necessary to protect both building occupants and the public water supply.
