Orbit 57624 1-Inch FPT Automatic Anti-Siphon Valve with Flow Control

Protect your irrigation with advanced backflow prevention

The Orbit Anti-Siphon Valve combines an atmospheric vacuum breaker with an inline forward-flow valve, delivering a smart solution for keeping irrigation lines free from back-siphon events. Built for residential spaces, professional installations, and even grow areas, this valve brings dependable protection and flexible control to outdoor watering zones. A 24 VAC solenoid and a manual actuation lever offer reliable operation whether you’re running a daily schedule, testing a zone, or performing routine maintenance.

Key design elements include an integrated flow control and a built-in scrubber filter. The flow control lets you fine-tune water delivery to meet changing landscape needs, while the scrubber filter helps minimize clogging by catching debris before it enters the valve. These features work together to support smooth, consistent performance in variable irrigation conditions.
