Jar Top Anti-Siphon Valve with Flow Control, 1 Threaded Female x Female

This valve model has been discontinued by the manufacturer, so a search for the new model DASASVF100 with Amazon ASIN B00004RAB0 is recommended. The valve features a combination of an electric remote control and an atmospheric backflow preventer in a single unit. An easy-to-turn, pressure-assisted flow control mechanism eliminates misting. The "Jar Top" lid can be quickly unscrewed without tools, allowing for easy access to the diaphragm, facilitating effortless maintenance and cleaning.

Designed for use with any 24-volt AC irrigation timer/controller, this valve can be utilized with a variety of watering devices, including Rain Bird spray heads, rotors, and impacts. A unique reverse-flow design helps prevent flooding in the event of an internal diaphragm failure, keeping the valve closed and conserving water.

Rain Bird, the manufacturer, is a privately held company founded in 1933 during the agricultural boom in California. Recognized as the world's #1 provider of irrigation products and services, Rain Bird offers over 4,000 water-saving irrigation solutions in more than 130 countries. With a legacy of innovation, the company has received over 450 patents worldwide, including the first one for irrigation in 1935 for their original impact-drive sprinkler, which revolutionized agricultural food production and ushered in a new era of irrigation globally.

Rain Bird's Anti-Siphon valves are installed above ground and designed to prevent backflow when properly installed, with the requirement to be placed at least 6 inches above the highest head on the valve line, and never have another valve installed downstream from the main valve. These valves feature a patented vacuum breaker, available for automatic or manual applications, and flow control models that regulate water flow to sprinklers to avoid misting.

Rain Bird's Anti-Siphon valves are constructed with a Buna-N (nitrile rubber) diaphragm, a water filter, and a captive spring, offering superior performance in harsh water environments. They also feature an energy-efficient, low-power encapsulated solenoid with a captured plunger and heavy-duty construction with stainless steel screws.

These valves are suitable for use in locations where a pressure vacuum breaker (PVB) or a double-check valve is required by local city codes to protect against backflow. Customers are advised to check their local codes to determine the appropriate valve requirements. The valves feature a 1-inch female pipe thread (FPT) inlet and outlet, and they meet I.A.P.M.O. and A.S.S.E. listing specifications, as well as being Canadian Standards Association approved.
