8" Dbl Detector Asy W/Os&Y Fxg

The Zurn Wilkins 8" Double Detector Assembly with OS&Y (Outside Stem and Yoke) Flanged Gate Valves is a crucial component for fire sprinkler systems, designed to protect the potable water supply from contamination. This robust backflow prevention device is specifically engineered for low-hazard applications, ensuring that fire protection substances and non-potable water do not reverse flow into the drinking water system due to backsiphonage or backpressure. It's an ideal solution for facilities requiring reliable backflow prevention and precise monitoring of their fire line.

• 8-Inch Size: This assembly features an 8-inch connection, suitable for larger fire sprinkler system mainlines.
• Double Check Detector Assembly (DCDA): Incorporates two independent check valves in series, providing reliable protection against backflow in non-health hazard conditions. The detector bypass system includes a meter to identify small leaks or unauthorized water usage.
• OS&Y Flanged Gate Valves: Equipped with Outside Stem and Yoke (OS&Y) resilient seated gate valves, providing clear visual indication of the valve's open or closed position and allowing for easy isolation during maintenance or testing.
• Backsiphonage and Backpressure Protection: Designed to prevent the reverse flow of water caused by both backsiphonage (negative pressure) and backpressure (downstream pressure exceeding supply pressure).
• Durable Construction: Features a lightweight stainless steel body, ensuring long-term corrosion protection and maximum strength.
• Horizontal or Vertical Installation: Approved for flexible installation in either horizontal or vertical orientations with flow-up.
• Easy Maintenance: Designed with a single access cover for streamlined maintenance and repair procedures, reducing downtime and associated costs.

This Zurn Wilkins 8" Double Detector Assembly offers enhanced peace of mind by safeguarding your potable water supply from potential contamination originating from your fire sprinkler system. The integrated metered bypass allows for proactive identification of costly leaks or unauthorized water usage, contributing to significant savings over time. Its versatile installation options and user-friendly design simplify both initial setup and ongoing maintenance, making it a reliable and cost-effective choice for maintaining water quality and system integrity.
