The Ames Colt C200 Fire Double Check Valve Assembly with OS&Y shutoff acts as a primary backflow prevention component in commercial plumbing and fire protection systems. It installs directly into fire sprinkler supply lines and municipal water networks to protect potable water supplies from non-health hazard contaminants during pressure fluctuations or system repairs. The assembly features dual check modules and Outside Stem and Yoke (OS&Y) resilient seated gate valves that give you a clear, visible indication of whether the valve is open or closed on the job site.

This assembly satisfies critical safety and performance requirements set by NFPA 13 and NFPA 25 standards for fire protection systems. It carries essential industry listings, including UL 1469 and FM approval, while complying with ASSE 1015 and AWWA C510 codes to ensure regulatory compliance during annual testing and inspections.

• Durable Body Construction: Fabricated from fusion-bonded epoxy-coated ductile iron or corrosion-resistant 304 stainless steel to withstand subterranean and mechanical room installations.
• Corrosion-Resistant Internals: Equipped with 300-series stainless steel springs and fasteners for extended durability during continuous operation.
• Precision Check Modules: Incorporates glass-filled thermoplastic check modules and select configurations feature patented Tri-Link check valves for low-pressure loss across the assembly.
• Reliable Sealing: Utilizes field-replaceable EPDM elastomeric discs that provide a tight, drip-tight seal to prevent backflow leakage and simplify long-term maintenance.
• High Pressure and Temperature Ratings: Rated for a maximum working pressure of 175 PSI (12.1 bar) and water temperatures ranging from 33°F to 140°F (0.5°C to 60°C).
• Flexible Installation: Supports horizontal and vertical upward flow orientations with grooved or flanged connection options.
• Accessible Test Ports: Includes test cocks to streamline inspection and proactive system management for annual testing protocols.
