Conbraco 4A-203-A2F Apollo 1/2" Bronze Reduced Pressure Zone Backflow Preventer

The Conbraco Apollo 4A-203-A2F is a 1/2-inch reduced pressure zone (RPZ) backflow preventer designed to protect potable water systems from contamination. This bronze body assembly provides the highest level of backflow protection, making it ideal for high-hazard applications in residential, commercial, and industrial plumbing systems.

Key Features:

• Reduced pressure zone design provides maximum backflow protection
• Durable bronze construction for long-lasting performance and corrosion resistance
• Integrated ball valves on inlet and outlet for easy shutoff and maintenance
• SAE threaded test cocks for simplified testing and compliance verification
• 1/2-inch connection size suitable for residential and light commercial applications
• Complies with ASSE 1013 and USC Foundation for Cross-Connection Control standards

This backflow preventer features two independent check valves with a pressure-monitored relief valve between them, ensuring that contaminated water cannot reverse flow into the clean water supply. The ball valves allow for easy isolation during testing or maintenance, while the SAE test cocks simplify field testing procedures. Ideal for protection against fertilizer injectors, boiler connections, and other high-hazard cross-connection scenarios.
