Featuring a reverse-flow design to prevent flooding, a low-power solenoid for efficient operation, and compatibility with all standard 24V sprinkler timers, it ensures reliable, automatic or manual watering. Built for below-ground installation, this durable valve offers long-lasting performance and water-saving benefits, making it a top choice for savvy homeowners and professionals alike. ## Description Rain Bird CP100 In-Line Automatic Sprinkler Valve, 1" Threaded Female Inlet x Female Outlet. Rain Bird manufactures only the highest quality In-Line valves. This residential and light commercial grade In-Line valve replaces all in-line irrigation valves installed below ground with 1" female threaded inlet and outlet. For use with any 24 volt AC irrigation timer/controller. Unique reverse-flow design helps prevent flooding in the event of internal diaphragm failure keeping the valve closed and saving water. Valve operates automatically or manually with manual bleed screw. Buna-N (nitrile rubber) diaphragm offers superior performance in harsh water environments. Features an energy-efficient, low power encapsulated solenoid with captured plunger. May be used with all types of watering devices including Rain Bird spray heads, rotors, and impacts. In-Line valves are installed below ground in a valve box downstream from the main line from a PVB or double-check valve. After installation and before startup, always flush the system of dirt and debris manually using the valve's external bleed screw. In-Line valves will not prevent back flow on their own; they require a back flow prevention device. Use In-Line 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 local city codes to determine what type of valves are required. Also available (sold separately) in 3/4" model: CP075.

Just make sure to buy the filter that is used for drip lines so the emitters don't get clogged up. **Q: I am currently using 3/4 inch ball valves to change flow from one circuit to another. Will this valve have the same flow capacity as the ball valve?** A: The same or better-----I think my inlet's and outlets are 1"----you will have to use reducers to adapt 3/4 " pipe. Please note that these valves are solenoid operated valves----as used with many electric 'timer' systems. I've found these solenoid valves to be trouble free over the many years that I've used them. **Q: I have a rainbird controller with 25.5v is it compatible with those valves?** A: Yes. Believe the valve is rated 24 volts +or- .
