FPT 100 Series Anti-Siphon Valve with Flow Control (57624) is an above-ground irrigation valve that prevents backflow using an integrated atmospheric vacuum breaker and adjustable flow control.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThis anti-siphon valve is engineered to protect sprinkler and irrigation systems from contaminated backflow while giving installers straightforward control and maintenance access. Built for outdoor cold-water irrigation, the unit combines a poppet-style atmospheric vacuum breaker, a 24 VAC solenoid for automatic operation, and a manual actuation lever. Its inline flow adjustment and internal scrubber filter reduce clogs and let you fine-tune water delivery for each zone.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the valve stop water from flowing backward into my supply?\u003c\/h3\u003e\n\n\u003cp\u003eThe valve includes an atmospheric vacuum breaker that opens to admit air as pressure drops, breaking any potential siphon. When the valve closes, the poppet automatically seals, preventing reverse flow into potable water lines. This design meets common anti-siphon installation practices and reduces contamination risk when installed correctly.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAtmospheric vacuum breaker with poppet that closes on shutdown\u003c\/li\u003e\n  \u003cli\u003eIn-line forward-flow design to enforce one-way movement\u003c\/li\u003e\n  \u003cli\u003eAbove-ground placement on risers ensures proper air admission\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation and wiring steps should I expect?\u003c\/h3\u003e\n\n\u003cp\u003eInstall the valve at least 6 inches above the highest sprinkler head in the controlled zone to ensure the vacuum breaker functions properly.
