How Do Sprinkler Valves Work? Rain Bird Irrigation

Great video, thanks for posting it.
I have installed one underneath my camper van to drain the grey water tank. It gets below zero where I live in the winter time, so I have completely wrapped the tank, hose and solenoid with insulation.
Is there anything wrong with keeping the solenoid completely wrapped in insulation and does the manual knob move when the valve is electrically opened/closed? I forgot to check before I did the installation...

I don't get it, but I believe you.

why do you have to have back up music?? it makes it hard to hear

Im trying to diagnose why one of my circuits wont turn on, it just has a light trickle when turned on. I opened the bonnet to find the pilot flow filter broken and laying in the bottom of the valve body. it seems like that is a very likely cause of my problem. Ill be picking up a rebuild kit tomorrow to see if this fixes it. Ironically this failure happened at the exact same time I tried testing a new sprinkler head on the same circuit for the first time (it worked fine earlier in the day with the old sprinkler head installed), causing me to think there was an issue with the new sprinkler. We will see though. if not, I'm calling a professional haha

Rainbird systems are garbage this whole thing is a propaganda

Every comment in this is fake they all start off exactly the same absolutely great explanation to prove explanation so fake their system is garbage the instructions you need aren't there in the instructions they do have for the stuff you don't need money as well be written in Japanese the whole system is absolute garbage avoided at all cost

Looks more like a Hunter vale ,than a Rainbird pvg

Great video and explanation.
Simple to understand.
Thank you!!

I have two valves that stay open, powered or not, is that bad solenoids?

So you need a valve to have enough pressure to the sprinkler system?

So many so called Irrigation repair specialists don't know this. So they don't know how to repair a valve, so they just replace them. Thus costing their customers more money.

Such good explanation. It's easy how a complicated system works with a small visual diagram. Thank you.

Beluga.

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...

Rainbird is my go to brand for control panel installs or valve replacements

You will never see a day laborer install the system that clean

Good Job, very informative.

Will this valve help reduce water pressure for a drip irrigation system? The water pressure in the greenhouse I’m working is very high and the drippers blow up.

Thank you! Very helpful!

Good soundtrack.

Very informative

Thank you, good explanation ...... now I need to identify and excavate my misbehaving valve to see why it doesn't want to close fully 😀

Can lowering flow control help stop water hammering

do these work for any position of the valve?

Its all wrong. The water comes in the bottom hole covered by the diaphragm and goes out the side. This all occurs UNDER the diaphragm. The top is for the tiny dribbles that actuate the valve!

Way better product than Toro offers.

I’m confused now though. When I blow out my lines prior to the winter, I pressurize the system & turn that smaller knob counter clockwise a half turn to get the air to flow through that particular valve/zone which then blows that zone out. Not sure how that works by looking at this animation as that little valve doesn’t seem to be doing anything.

Good explanation and clever valve design. I have no need for this type of valve or an irrigation system, but still enjoyed the video.

Nice

This video is very interesting 😮😀😀😁

Should the solenoid be in OFF position normally? When I turn the solenoid in ON position (manually) my Orbit station cannot stop the water from flowing even if programmed to be off. But if I close the solenoid (manually) water doesn't run even if the programmer is telling it to. I'm thinking it could be a fault in the Orbit station. Any help would be appreciated. Thanks.

I used to work on the industrial version of these. Largest one I worked on was 36 inches.

This was actually really fucking cool. Here I am. 29 years old, two kids sleeping, wife in bed, and I’m sitting on the toilet, post shit, watching videos about how my sprinkler valve works. I guess this is what adulting really is

So it's like a transistor, where a little current controls a much bigger current!

Can 24V AC selenoid vlave work on 24V DC power?

Wow. Who knew I'd be left amazed watching a video about a sprinkler valve. Thanks.

Great Video! Thank you!

Will the valve work without any water pressure? What is the minimum amount of pressure to make the valve work?

If one has a 3/4" inlet will it be a "full flow" 3/4" going out?...OR does this valve cause one to lose water volume as opposed to a full flow ball valve?

Impressive

What if the valve fails to shut off due to the diaphragm getting a hole or anything else . Is there a way to turn off the water manually?

genius design..!!

My Rainbird valve doesn’t turn on manually turning the solenoid, the sprinklers don’t pop up, just low flow. What should I do? Thanks in advance

What is the name of a black screw above a Pilot Flow Filter? What is it for?

Is there any video or document I can refer to know how to connect solenoid to rainbird controller (LXME)

I have a new one i mounted vertically that doesn't seem to work as it always allows water to flow. Does it need mounting horizontally?

Hi, So, does that mean there can not be a backflow from the outlet to inlet when the solenoid closes. I have the inline values in my front and back yard, and I do not know if need a backflow preventer or not. Please let me know urgently

what if the valve keep receiving water for a long period, there is some risk for it to explode ?
