Fire Protection Double Check Valve Zurn Wilkins DCV

The Zurn Wilkins DCV Double Check Valve safeguards potable municipal water supplies from contamination within fire suppression assemblies, sprinkler networks, and standpipe systems. Operating via two independently acting internal check modules, the valve blocks reverse flow and cross-connection hazards to maintain water purity. This professional-grade assembly satisfies municipal plumbing codes and regulatory frameworks, complying with NFPA guidelines and AWWA C510 standards while passing rigorous UL 1469, FM, and ASSE 1015 testing protocols for commercial retrofits and new infrastructure installations.

Key Features & Construction

• Durable Body: Built with a fusion-bonded epoxy-coated ductile iron body adhering to ASTM A536 specs for long-term corrosion resistance.
• Stainless Steel Hardware: Equipped with 300-series stainless steel springs and fasteners to withstand harsh fire system conditions.
• Thermoplastic Modules: Utilizes high-strength, glass-filled thermoplastic check modules with reversible, replaceable EPDM elastomer discs for tight sealing.
• OS&Y-Free Footprint: Omits the traditional Outside Stem and Yoke valve design to reduce overall size, fitting easily into tight mechanical rooms or underground setups.
• Flexible Installation: Supports rapid integration into standard piping layouts with both horizontal and vertical upward flow orientations.
