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

The discontinued valve model has been replaced by a new model, DASASVF100, with Amazon ASIN B00004RAB0. This combination electric remote control valve and atmospheric backflow preventer unit features an easy-to-turn, pressure-assisted flow control mechanism that eliminates misting.

The "Jar Top" lid can be quickly unscrewed without tools, allowing 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 a privately held company founded in 1933 during the agricultural boom in California. They are recognized as the world's number one provider of irrigation products and services, offering over 4,000 water-saving irrigation solutions in more than 130 countries.

The company's Anti-Siphon valves are installed above ground and will prevent backflow if properly installed, as required by city codes in many locations. These valves feature a patented vacuum breaker, available for automatic or manual applications, and the flow control models regulate water flow to sprinklers to avoid misting.

Rain Bird's Anti-Siphon valves work with any standard sprinkler timer and are constructed with a Buna-N (nitrile rubber) diaphragm, a water filter, and a captive spring, offering superior performance in harsh water environments. The energy-efficient, low-power encapsulated solenoid with a captured plunger ensures reliable operation, and the heavy-duty construction with stainless steel screws provides durability.

Rain Bird is committed to the "Intelligent Use of Water" and 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 in irrigation. The company's legacy is to design and manufacture only the highest-quality products, and they have received numerous recognition awards from their valued partners.
