Rain Bird Jar Top Anti-Siphon Valve with Flow Control, 1 Threaded Female (Discontinued, Replaced with DASASVF100)

The manufacturer has discontinued this valve model, so you should search for the new model DASASVF100, which has the Amazon ASIN B00004RAB0. This unit combines an electric remote control valve and an atmospheric backflow preventer. Its pressure-assisted flow control mechanism eliminates misting, and the easy-to-turn feature makes it simple to operate. The threaded "Jar Top" lid can be quickly unscrewed without tools, providing easy access to the diaphragm for effortless maintenance and cleaning. This valve is designed for use with any 24-volt AC irrigation timer/controller.

The unique reverse-flow design helps prevent flooding in the event of an 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 impact sprinklers.

Rain Bird, the manufacturer, is recognized as the world's leading provider of irrigation products and services. The company was founded in 1933 during the agricultural boom in California and has since received over 450 patents worldwide, including the first one for irrigation in 1935 for their original impact-drive sprinkler. This sprinkler revolutionized agricultural food production and ushered in a new era in irrigation worldwide.

Rain Bird's Anti-Siphon valves are installed above ground and will prevent backflow if properly installed. They should always be installed at least 6 inches above the highest head on the valve line, and no other valve should be installed further down the line from the main valve. These valves feature Rain Bird's patented vacuum breaker, available for automatic or manual applications.

The flow control models regulate the water flow to sprinklers, preventing misting. All of Rain Bird's Anti-Siphon valves work with any standard sprinkler timer. The Buna-N (nitrile rubber) diaphragm, with a water filter and captive spring, offers superior performance in harsh water environments. The energy-efficient, low-power encapsulated solenoid with a captured plunger ensures reliable operation.

Rain Bird's products are constructed with heavy-duty materials, including stainless steel screws. These valves should be used in locations where a pressure vacuum breaker (PVB) or a double-check valve is required by local city codes to protect against backflow. Users should check their local city codes to determine the appropriate valve requirements.

The valves feature 1-inch female pipe thread (FPT) inlet and outlet, and they meet I.A.P.M.O. and A.S.S.E. listing specifications. They are also Canadian Standards Association approved. Additionally, a 1-inch model, JTVASF075, is available separately.

Rain Bird's commitment to the "Intelligent Use of Water" extends beyond their products to education, training, and services for the industry and the community. The company's legacy is to design and manufacture only the highest-quality irrigation products.
