This professional-grade anti-siphon valve is designed to replace Rain Bird and other irrigation valves installed above ground, featuring a 3/4-inch female threaded inlet and outlet. It works with any 24 VAC irrigation timer. The valve’s unique reverse-flow design helps prevent flooding in the event of internal diaphragm failure, keeping the valve closed and conserving water when unexpected issues occur.
The adjustable flow control feature prevents wasteful misting when water pressure is too high. A top-mounted, easy-turn flow control knob allows you to optimize flow to each zone, permitting sprinklers to water at their most efficient rate for more uniform coverage across your lawn or garden. This combination of anti-siphon protection and flow control makes it an ideal solution for maintaining efficient, reliable irrigation.
