Built with a heavy-duty \u003cstrong\u003ebronze body\u003c\/strong\u003e, this assembly includes integrated \u003cstrong\u003eApollo ball valves\u003c\/strong\u003e featuring \u003cstrong\u003estainless steel handles\u003c\/strong\u003e and nuts to resist atmospheric corrosion in the field. The internal design utilizes a \u003cstrong\u003emodular check valve cartridge\u003c\/strong\u003e with a \u003cstrong\u003ecaptured stainless steel spring\u003c\/strong\u003e and a reversible silicone seat disc, simplifying maintenance for technicians. A key technical advantage is the \u003cstrong\u003ebuilt-in freeze resistance\u003c\/strong\u003e relief valve, which helps protect the internal components from damage during intermittent temperature drops. This \u003cstrong\u003e1\" vacuum breaker\u003c\/strong\u003e is rated for a \u003cstrong\u003emaximum operating pressure\u003c\/strong\u003e 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 \u003cstrong\u003eASSE 1020\u003c\/strong\u003e compliance, ensuring it meets strict \u003cstrong\u003eirrigation backflow\u003c\/strong\u003e standards for both residential and light commercial applications.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModular Cartridge Design:\u003c\/strong\u003e Allows for quick internal servicing without the need for specialized tools.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFreeze Protection:\u003c\/strong\u003e Features an integral relief valve to mitigate damage from unexpected freezing conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e Constructed with a high-strength \u003cstrong\u003ebronze body\u003c\/strong\u003e and corrosion-resistant hardware for long-term outdoor exposure.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVersatile Installation:\u003c\/strong\u003e Approved for both vertical up and horizontal piping configurations to fit varied site requirements.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChloramine Resistance:\u003c\/strong\u003e Includes high-grade elastomers designed to withstand treated water chemical exposure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Conbraco 4A-505-A2F suitable for indoor use?\u003c\/strong\u003e\u003cbr\u003e\nThis 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 4A and 4ALF models?\u003c\/strong\u003e\u003cbr\u003e\nThe 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I repair the internal check valve in the field?\u003c\/strong\u003e\u003cbr\u003e\nYes, 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
