10" Reduced Pressure N Pattern With OSY LF Valve

The 10" Reduced Pressure N Pattern With OSY LF Valve by Conbraco protects potable water supplies in residential fire sprinkler systems by preventing contaminated water from flowing backward. This reduced pressure backflow preventer installs directly at the interface between the public water supply and your fire protection system, satisfying municipal requirements to guard against backsiphonage and backpressure.

Operating via a reduced pressure principle, the dual check valve system and pressure relief assembly protect health hazard applications while regulating consistent internal pressure. The OS&Y (Outside Stem & Yoke) gate valve design gives you an immediate visual indication of whether the valve is open or closed, ensuring water flow stays active and accessible during emergencies.

Key Features & Construction

• Corrosion-Resistant Body: Crafted from high-quality materials to deliver dependable, long-lasting performance in demanding environments.
• OS&Y Gate Valve Design: Provides a clear visual open/closed position indicator so you can instantly verify that water flow is not mistakenly shut off.
• Lower Head Loss: Engineered to minimize pressure drop compared to alternative valve types, keeping water pressure steady.
• Optimized Flow Path: Strategically designed internal geometry ensures your fire suppression system operates effectively when deployed.
• Pressure Relief Assembly: Regulates consistent pressure levels within the equipment to handle fluctuating supply conditions.

Always verify local Authority Having Jurisdiction (AHJ) mandates and consult the manufacturer's engineering guidelines prior to assembly and installation.
