The 950XLTBF Double Check Valve Assembly by Zurn is engineered for professionals handling non-potable water and fire protection systems. This assembly offers reliable backflow prevention, combining durable construction with compliance to strict safety standards to ensure system integrity and longevity.

• Corrosion-Resistant Body: Manufactured from robust iron with a fusion-bonded epoxy coating, it withstands harsh chemicals and particulates common in non-potable water environments.
• High-Durability Internal Components: Features 300-series stainless steel springs and fasteners designed for extended high-cycle use, minimizing wear over time.
• Advanced Check Modules: Constructed from glass-filled thermoplastic materials, these modules maintain dimensional stability and resist wear even under turbulent flow.
• Replaceable Sealing Seats: Equipped with reversible EPDM elastomer seats that ensure a tight seal and simplify maintenance, reducing service downtime.
• Regulatory Certifications: UL 312 listed, FM Approved, and compliant with NFPA 13 and NFPA 25, meeting essential fire protection system requirements.
• Pressure and Connection Flexibility: Supports pressures up to 175 PSI and fits ANSI B16.1 flanged or AWWA C606 grooved connections, suitable for horizontal or vertical upward installations.
• Compact and Practical Design: Sized for installation in tight spaces such as underground vaults and mechanical rooms, ideal for both retrofits and new builds.
• Easy Maintenance: Integrated test ports and reversible sealing seats allow straightforward inspection and servicing without disrupting system operation.

This valve assembly provides fire protection engineers and system integrators with a trusted solution for managing backflow risks in non-potable water applications. Its corrosion resistance and durable components reduce maintenance frequency, while its certification assures regulatory compliance. Ideal for systems using reclaimed irrigation or industrial process water, it helps maintain water quality and safety by preventing contamination and supporting reliable, long-term fire protection system performance.
