4"Dbl Ck Det Asy W/Os&Ypiv Gxg

The Zurn Wilkins 4" Double Check Detector Assembly (DCDA) with OS&Y Pivoting Grooved Connections is a critical component for fire protection systems, engineered to safeguard potable water supplies from contamination while providing essential leak detection capabilities. This assembly is designed for use in low-hazard fire sprinkler applications, ensuring system integrity and compliance with safety regulations.

• Double Check Detector Assembly (DCDA): This device combines two independent check valves in series with a metered bypass system, offering robust backflow prevention and the ability to detect small leaks or unauthorized water usage within the fire sprinkler system.
• 4-inch Size: Engineered for 4-inch pipe systems, providing appropriate flow capacity for many commercial fire protection applications.
• OS&Y (Outside Screw and Yoke) Gate Valves: Features OS&Y shut-off valves, where the threaded stem is visible outside the valve body. This design allows for quick and clear visual confirmation of the valve's open or closed position, which is crucial for emergency situations and routine maintenance in fire protection systems.
• Pivoting Grooved Connections: Utilizes grooved ends for pipe connection, offering flexibility and ease of installation. Grooved systems are known for faster assembly and can reduce labor costs compared to other connection methods.

This Zurn Wilkins DCDA offers peace of mind by preventing the backflow of non-potable water from the fire sprinkler system into the main water supply, protecting public health. The integrated detector bypass with a water meter helps identify potential leaks or unauthorized water usage, allowing for proactive maintenance and ensuring the fire suppression system remains fully operational. Its robust construction and OS&Y valves contribute to reliable water supply control and simplified visual inspection, which is vital for maintaining system readiness and complying with fire safety standards. The pivoting grooved connections facilitate quicker and more versatile installation, making it an efficient choice for both new fire protection designs and upgrading existing systems.
