- Have you ever wondered how irrigation control valves work? In this short video, we'll take you on a tour inside a Rain Bird valve to learn about the parts and technology that help keep water flowing exactly when and where you want it.

I watched twice and still do not understand 😢 exactly how the water pressure in the top over powers the flow from the supply line.
This is a great explanation of valve operation, however one thing was omitted: the spring above the diaphragm. If the valve is closed simply by the water pressure above the diaphragm, then why is there a spring there? And why does the valve fail to close if the spring is removed? That spring seems important...
Whoever put this together....thank you!!
You will never see a day laborer install the system that clean
why do you have to have back up music?? it makes it hard to hear
how can I buy
This animation allowed me to finally figure out what that little screw was for. I had a station that had power going to it but the sprinklers wouldn't activate. After turning the screw counter clockwise, some water spewed out of it and the sprinklers for that station started working again. If I tighten the small screw once the sprinklers get going, about 30 seconds later they'll shut off. Is this normal? What gives?
So it's like a transistor, where a little current controls a much bigger current!
What does the valve seat screw do
Wow. Who knew I'd be left amazed watching a video about a sprinkler valve. Thanks.
Extremely impressive and informational. Thank you for sharing this!!
Such good explanation. It's easy how a complicated system works with a small visual diagram. Thank you.
Rainbird is my go to brand for control panel installs or valve replacements
Good explanation and clever valve design. I have no need for this type of valve or an irrigation system, but still enjoyed the video.
Currently working on a golf course with lots of rainbird stuff so this is extremly helpful as I am fairly new with all this.
THANK YOU RAIN BIRD, EXCELLENT RUclips VIDEO!!! Easy to Understand!!!
Great video and explanation.
I used to work on the industrial version of these. Largest one I worked on was 36 inches.
That’s cool. I thought that it was a motor that turned the valve on and off. Now I have to look up solenoid.
The water flow from the hole when electromagnet lifts is acting as a lever to lifts the diaphragm because there is a small hole in the diaphragm that fills the chamber but in higher water flow lifts the diaphragm.When the water flow stops from the electromagnet hole the water pressure then pressures back the diaphragm to close.Similar to the electric relay action.
