Reliable, Tough and Easy to Use—This Valve Has It All. Anti-siphon valves that prevent potable water from being contaminated by irrigation backflow must be dependable. They must also be rugged enough to provide continuing protection even in punishing environments. But even though they’re tough, they should be easy to work with.

Orbit’s new Anti-Siphon Valve is all that … and more. In areas where backflow prevention is required, Orbit’s Anti-Siphon Valve is a “must have.” Its advanced design incorporates an integrated atmospheric vacuum breaker to eliminate the possibility of backflow. And of course, the valve meets ASSE, CSA and IAPMO standards.

FEATURES AND BENEFITS

• Automatic valve—For convenience and water savings when used with 24-volt irrigation controllers
• Anti-siphon design—Integrated anti-siphon vacuum breaker design does not allow water downstream of the valve to siphon back into the primary water source (meets ASSE, CSA and IAPMO standards)
• Rugged—Double seal TPR diaphragm ensures years of reliable performance
• Stainless steel metering system—Provides a continual cleaning action every time the valve goes on or off
• Leak proof—Buna-N valve seat seal provides positive closure preventing seepage
• Flow control—Meets the needs of your landscape and environmental conditions by “tuning in” sprinkler water droplet size
• Manual internal bleed—Allows manual watering with no external discharge.
