6" Double Check Detector N Pattern With OSY Valve

Protect your potable water supply with the Ames 6" Double Check Detector N Pattern With OS&Y Valve, engineered specifically for commercial fire protection systems. Installed inline on fire sprinkler and service mains, this assembly stops contaminated or stagnant water from reentering clean municipal lines during backpressure or backsiphonage events. It satisfies stringent cross-contamination control requirements and complies with local plumbing and fire codes for commercial life safety installations.

The integrated detector assembly continuously monitors low-flow conditions to catch unauthorized water usage, leakage, or potential backflow early. Featuring a fail-safe dual check valve configuration alongside corrosion-resistant internal and external materials, the unit withstands demanding mechanical room environments. The 6-inch N pattern layout streamlines installation in standard piping configurations while optimizing flow rates to minimize pressure loss. Integrated outside screw and yoke (OS&Y) gate valves provide a clear visual indicator of open or closed status for rapid inspection and positive shutoff during system maintenance.

Key Features & Construction

• 6-Inch N Pattern Design: Streamlines pipe alignment and layout during installation while maintaining optimal water delivery.
• Dual Check Valve Assembly: Prevents reverse water flow across varying pressure conditions to isolate the fire suppression supply.
• OS&Y Gate Valves: Delivers immediate visual open/closed verification and dependable isolation for servicing.
• Continuous Detection Technology: Monitors unauthorized flow, leakage, or backflow events through a dedicated bypass meter assembly.
• Corrosion-Resistant Build: Utilizes rugged materials built to endure harsh environments within fire protection assemblies.
• Low Maintenance Layout: Straightforward access to internal components minimizes system downtime during regulatory testing.
