The 10" Double Check Valve with OS&Y Design is engineered specifically for commercial and industrial fire protection systems to prevent hazardous backflow contamination and maintain water supply integrity. Designed for installation in mechanical rooms or underground assemblies, it utilizes internal check modules to stop reverse flow and protect potable water systems from non-health hazard pollutants.
This assembly complies with NFPA 13 and NFPA 25 standards for the installation and inspection of fire sprinkler systems and water-based fire protection systems. It satisfies strict regulatory mandates for backflow prevention, ensuring continuous operational readiness, reliable system testing, and full code compliance for commercial life safety infrastructure.
Key Features & Construction
- Ductile Iron Body: Fusion-bonded epoxy-coated ASTM A536 ductile iron construction delivers superior corrosion resistance and mechanical strength for underground or mechanical room deployments.
- OS&Y Design: Outside Stem and Yoke configuration exposes the valve stem externally for instant visual position confirmation and streamlined maintenance without internal disassembly.
- Corrosion-Resistant Internals: Incorporates 300-series stainless steel springs and fasteners alongside glass-filled Noryl™ check modules to resist pressure deformation and extend service life.
- EPDM Elastomer Sealing: Reversible and replaceable EPDM elastomer discs provide chemical resistance tailored specifically for fire service water supplies.
- Flexible Installation: ANSI B16.1 flanged end connections establish standardized piping interfaces that support horizontal and vertical upward flow orientations.
- Operating Parameters: Rated for a maximum working pressure of 175 PSI (12.1 bar) and a temperature range of 33°F to 140°F (0.5°C to 60°C).
