Conbraco Industries 4A-505-A2F Breaker
The Conbraco 4A-505-A2F Breaker, also known as the Apollo PVB4A, is a 1-inch pressure vacuum breaker engineered for reliable backflow prevention in potable water systems. Built with a heavy-duty bronze body, this assembly includes integrated Apollo ball valves featuring stainless steel handles and nuts to resist atmospheric corrosion in the field. The internal design utilizes a modular check valve cartridge with a captured stainless steel spring and a reversible silicone seat disc, simplifying maintenance for technicians. A key technical advantage is the built-in freeze resistance relief valve, which helps protect the internal components from damage during intermittent temperature drops. This 1" vacuum breaker is rated for a maximum operating pressure of 150 psi and a temperature range of 33°F to 140°F. Professionals prefer the 4A-505-A2F for its low pressure loss and ASSE 1020 compliance, ensuring it meets strict irrigation backflow standards for both residential and light commercial applications.
Key Benefits- Modular Cartridge Design: Allows for quick internal servicing without the need for specialized tools.
- Freeze Protection: Features an integral relief valve to mitigate damage from unexpected freezing conditions.
- Durability: Constructed with a high-strength bronze body and corrosion-resistant hardware for long-term outdoor exposure.
- Versatile Installation: Approved for both vertical up and horizontal piping configurations to fit varied site requirements.
- Chloramine Resistance: Includes high-grade elastomers designed to withstand treated water chemical exposure.
Is the Conbraco 4A-505-A2F suitable for indoor use?
This pressure vacuum breaker is primarily designed for outdoor applications, such as irrigation systems, and should be installed at least 12 inches above the highest downstream outlet. Because it may discharge water during operation, ensure proper drainage is provided if used in a sensitive area.
What is the difference between the 4A and 4ALF models?
The 4A-505-A2F is the standard bronze version, while the 4ALF series is manufactured using lead-free alloys. Always verify local plumbing codes to determine if a lead-free assembly is required for your specific potable water application.
Can I repair the internal check valve in the field?
Yes, the unit features a unique canopy detachment and a modular check cartridge. The seat and silicone disc are reversible and replaceable, making field maintenance efficient for service contractors.
