Product description

Product Description

This valve model was Discontinued By Manufacturer, search for new model DASASVF100 with Amazon ASIN B00004RAB0. Combination electric remote control valve and atmospheric backflow preventer in one unit. Features threaded "Jar Top" lid which quickly unscrews without tools allowing you to easily access the diaphragm for effortless maintenance and cleaning. For use with any 24 volt AC irrigation timer/controller. A unique reverse-flow design helps prevent flooding in the event of internal diaphragm failure keeping the valve closed and saving water. This valve can be used with all types of watering devices including Rain Bird spray heads, rotors, and impacts. From the Manufacturer: Rain Bird manufactures only the highest quality Anti-Siphon valves. Anti-Siphon valves are installed above ground and will prevent back flow if properly installed. Anti-Siphon valves should always be installed at least 6" above the highest head on the valve line, and should never have another valve installed further down the line from the main valve. Our Anti-Siphon valves also feature our patented vacuum breaker–available for automatic or manual applications. Flow control models regulate the flow of water to sprinklers to avoid misting. All of our Anti-Siphon valves work with any standard sprinkler timer. Buna-N (nitrile rubber) diaphragm with water filter and captive spring offers superior performance in harsh water environments. Features an energy-efficient, low power encapsulated solenoid with captured plunger. Heavy-duty construction with stainless steel screws. Use Anti-Siphon valves in locations where the use of a pressure vacuum breaker (PVB) or a double-check valve is required by city codes to protect against back flow. Check your local city codes to determine what type of valves are required. 1" female pipe thread (FPT) inlet and outlet. Meets I.A.P.M.O. and A.S.S.E. listing specifications. Canadian Standards Association approved. Also available (sold separately) in 3/4” model: JTVAS075. Rain Bird “The Intelligent Use of Water”
