Protect your potable water mains from contamination with the Zurn Wilkins Double Check Valve Assembly. This precision-engineered backflow preventer installs directly into industrial, commercial, and fire sprinkler networks to block backflow effectively while minimizing pressure loss during high-demand events. It satisfies stringent life safety mandates by complying with NFPA 13 and NFPA 14 standards for fire sprinkler and standpipe systems, fulfilling critical code requirements for containment.
The integrated dual check mechanism blocks reverse flow while preserving system flow rates. The ductile iron body provides high mechanical strength and excellent corrosion resistance for demanding industrial environments. Reliable seals and seats are engineered for longevity and frequent cycling under the variable pressure loads typical of fire protection networks. Flexible integration offers compatibility with NRS or grooved connections to simplify installation in both new construction and retrofit projects.
