Great Solenoid
The product was well packaged and the control "valve" was sealed in a cap on the solenoid. When installed, it worked perfectly - can't ask for anymore.

Great product
Part fit as expected, and worked perfectly on my Nelson valve. I would definitely recommend this product.

I wasn't sure why a certain zone was not turning in consistently. Also had water leaking from one valve in box when I would manually turn on. Tried switching solenoid and presto - zone works fine. Determined type of valve by identifying R811 on existing and searching on sprinkler warehouse site. Because they were so in expensive I bought two incase a similar problem pops up (no pun...).
June 22, 2015
Works fine and shipping was quick
It fit one of my 20+ years old Richdel R-204 valves perfectly and worked as expected. It comes with an O-ring and the leads are long enough for any imaginable configuration. I would recommend this if you have any old Richdel or Irritrol 204/205 or compatible valve.

I installed an R811-24VACG solenoid on an Irritrol 205SF valve. The valve would not shut off when I restored water pressure. The new solenoid had a longer plunger then the old one, and didn't stick out quite as much in the off position.

I finally gave up and repaired the old solenoid, and it now works fine.

Is the R811 really a replacement for the Irritrol solenoid ?
A shopper on Aug 8, 2011
I have an Irritrol 1001-1990 valve, will this solenoid work with that model? They look the sme.

Thank you,
A shopper on Jul 11, 2013
BEST ANSWER: It most likely will work on that valve. I have an older model of the valve and this solenoid worked but the white ring at the tip had to be removed since these solenoids are for the newer valves. to be sure contact Irriatrol and give them the valve model number and they'll give you the right part numbers. be sure to change the diaphragm if that hasn't been changed in a while
My solenoid made in Mexico will not fit the old valve, how do I fix it?
A shopper on Mar 25, 2012
How does this solenoid get replaced? How to take off old one, put on new?
Jim F on May 5, 2013
BEST ANSWER: The solenoids on all sprinkler system are replaced the same way
all you have to do is to cut the two wires just before the wire nuts ther will be one colored wire going to one wire nut and one or more white wire going to the other wire nut. All you have to do remove the solenoid from the valve is to unscrew it and screw in the new one now take one of the black wires from the solenoid and the colored wire and twist them togather and put them in to a waterproof wire nut and do the same with other wires but make sure the water is truned off to the whole system before you do this.
does the white end cap come off to fit my richdel r216 valve? does anyone know?? thanks
dee b on Nov 30, 2012
BEST ANSWER: The white end is not a cap, it's part of the solenoid. The white end is threaded and screws into a valve, the other end has the two electrical wires. I do not know if this solenoid fits your valve.
the wires from Sil Solenoid on my Irritrol 100 valve broke off. Is R811 the proper replacement?
george j on Dec 21, 2013
BEST ANSWER: It looks right
Hi. I recently purchased a few of these solenoids from you. My valves are older and I beleive I need to remove the white ring around the top of the solenoid for the solinoid to work properly with my older valves. Can you tell me how the white ring is supposed to be removed? Thanks.
MattK on Aug 8, 2013
BEST ANSWER: I found that you do have to remove the white retainer which keeps the center plunger captive. Make sure that check the "O" ring for any damage as installing it with the white ring may cause damage - it did for me. Also, if you have one of the screw on, jar lid style tops, there is a tiny "O" ring dead in the cap. If it moves on installation, it will leak and cause the valve the shudder or stay on! That size is 1/4 OD and 1/8 ID. It is far easier to replace that by removing the press fit plastic fitting from the cap underside than the entire valve!!!
I hear a clacketing sound and feel a vibration when running the irrigation system. I think it's the solenoid. What causes that and does it mean that it's running properly?
A shopper on Jan 21, 2013
BEST ANSWER: I am only a homeowner and not an expert -- so, you have been warned. Is there water flowing from the zone when the zone is turned on? Is water stopped from running on the zone when it is turned off? Does the solenoid leak? If everything is working as it should be, I probably wouldn't worry about it. You could swap the solenoid for another in another zone and see if the noise goes away... You could check the voltage that the solenoid is getting when it is turned on...
Is this an AC or DC solenoid?
A shopper on Jun 25, 2012
BEST ANSWER: AC coil low voltage 24 volts.
does this replace toro ez flow and does it have 2 or 3 wires ?
A shopper on Apr 9, 2013
BEST ANSWER: It has 2 wires. Unfortunately it did not fit my Rainbird vavle. I then took my old valve and solenoid apart and leaned. Old valve works just fine now,
is this product made in usa or mexico?
A shopper on Mar 24, 2012
Hi my name is Ivan and I would like to know. How long is the wire connected to the solenoid? Thanks
Ivan T on Aug 20, 2018
BEST ANSWER: The ones I bought are all installed, but going off memory, I believe they are about 10-12” long.
I have the Richdel R811 solenoids. I want to replace my old Richdel controller. Does it matter what controller I get due to the amps output of the controller?
Frank D on Oct 18, 2013
BEST ANSWER: Find out what the draw of the solenoids is and that will tell you how much amperage the controller must output. Or look at the old controller and see if it has any amp "output" on it.
The picture shown for this has 3 wires and my solenoid only has two. What do you do with the extra wire?
jim b on Jun 3, 2020
BEST ANSWER: If you take a closer look at the picture you'll see only 2 wires. The end of one of the 2 wires is butted up against the solenoid making it look like a 3rd wire, but it's not. You can see that the insulation is partially stripped from it.
how to tell common wire from on solenoids ?
buck m on Oct 10, 2016
BEST ANSWER: These particular solenoids aren't polarized, so no common wire.
The solenoid I am replacing is Richdel R701.Will the R811 universal work. Thanks

BEST ANSWER: Irritrol R 811-24 replacement solenoid - valve operator
Replacement Solenoid for Irritrol 205, 216, 217 & 700 Series Electric Zone Valves.

When your solenoid (electric valve operator) makes a buzzing noise it can mean that your solenoid is, "on it's way out" and may need replacement soon. If your solenoid shorts out, you can replace it quickly and easily with the Irritrol R 811 -24!

Irritrol R 811 -24 VAC Irrigation Solenoid, is the same as & is a replacement for Hardie®, Richdel® and Irritrol® Systems universal encapsulated solenoid, operator for Irrigation Zone valves.

Irritrol R-81124 Replacement Solinoid Features:

•Captive hex plunger
•.40 amp inrush,
•.20 amp holding.
does any brand solenoid interchange with 80s rainbird valves?
A shopper on Apr 29, 2017
BEST ANSWER: Unfortunately No. It has been my experience that ach brand of electronic valve requires the same brands solenoids.
where is the solenoid located at?
A shopper on Jan 22, 2012
BEST ANSWER: I replaced the solenoid in my system in 2010 using this unit. You will find the solenoids in your green junction box probably close to where your sprinkler system starts on your lawn. I believe the unit comes with installation instructions. Not a tough job.
Is the 811 a replacement for the Irritrol 2400 valve?
A shopper on Jun 27, 2011
BEST ANSWER: A selenoid is a part of irrigation valve, so it will not replace a valve of any kind. Bohemia used R811 to replace selenoids on Nelson irigation valves and it works well.
how to replace solenoid valve on Irritrol 2400t I can only turn the valve about 3/4 of a turn before it is stopped by a plastic tab I could break this tab of but won't until some one says it will be OK ?
barry k on Sep 24, 2018
BEST ANSWER: First disconnect the wires from the old solenoid. Now hold the oval plastic tab and unscrew the solenoid (its the barrel shaped part). When you screw in the new solenoid, center the oval plastic tab before tightening. Now reconnect the wires.
Will this product work on an old Richdel 2400 1 inch (I repeat 1 inch) valve? Thank you.
Jonathan S on Apr 2, 2018
BEST ANSWER: It will. It’s works with current irritrol valves which are the same as a richdel. You may have to remove the white ring that encapsulates the plunger though. Easily done by grabbing the edge with needle nose pliers or a knife.
I purchased the R8111-24VACG Irritrol solenoid for use on a Lawn Genie Model 204LG valve that is approx. 25 years old. The working end of the solenoid looks completely different which isn't the major issue, the threads don't work correctly to insert and tighten in the valve assembly. It wobbles like the threads are either wrong or the part wasn't molded correctly. Any thoughts, is this the right part? I have used similar parts years ago but don't know brand or model # and they worked fine. Thanks! PS, I need these asap, do any of the big box stores carry to just get one or two to get key zones working?
Gregory S on May 29, 2017
BEST ANSWER: I believe you have the wrong model. Ours was also very old, but fitted perfectly, working well
I have Richdel valves with a R701 solenoid. Will this solenoid work as a replacement?
Debbie W on Jun 16, 2016
BEST ANSWER: I've usually had to replace the top of the valve with the solenoid because I suspect the plunger in this is different.
do you have a replacement solenoid for rain bird apas-o75 ?
Bob S on Jun 15, 2016
BEST ANSWER: Yes easy to install and great price
have a Richdel solenoid valve Model # R216PR, what replacement solenoid do I use?
A shopper on Nov 10, 2015
BEST ANSWER: If Sprinkler Warehouse does not have your solenoid....Unplug your controller and remove your solenoid. Take it with you to shop for solenoids. Pay particular attention to the type of threads and length of the stem. If it is not a perfect match it won't work. If you find one that looks close, try it and see if it will work. If you buy a solenoid from Sprinkler Warehouse and it won't work, they will let you send it back.
I have a 115 volt system. I want to convert to 24 volts. what do i need to do that?
John M on Dec 13, 2014
BEST ANSWER: You most likely DO NOT have a 110 volt system, yes the controller plugs into a normal 110 outlet, but there is either a transformer which plugs into the outlet, or there is a transformer inside the cabinet. No sprinkler system used 110 volts, that would be asking to be electrocuted.
I have a irritrol valve,one of the wires on the solenoid came apart,I have managed to solder it back & it works okay,however the pump cavitates sometimes & flow drops,when I open bleed valve on top of valve body the flow resumes.To be hassle free I have bought a replacement solenoid.I am thinking to open valve body & check diaphragm before I run the new one.is this advisable?
giancarlo p on Nov 2, 2014
BEST ANSWER: The valve can be opened easily and checked, my valves (14-15 years old) looked good, I replaced the diaphragm & o-rings & solenoid anyway, but still had lower flow than w/ bleed open. they had to be replaced, something about wear in the passages inside. hope it helps. CC
I am looking for a mother board for my Hardie sprinkler system which is about 18 years old. Where can I get one from?
A shopper on Sep 22, 2014
BEST ANSWER: I have tried this journy before, my whole hearted advice-" buy a new control box". The boards are the same price as a new box, and now have more options on them.
Is this for my Irritrol 217B 2 Inch valve?
Bob C on Apr 11, 2014
BEST ANSWER: Y es ir works for the irritrol 217 2 inch valve
Will this solenoid work on an Irritrol 2711 series valve?
A shopper on Nov 3, 2013
BEST ANSWER: Not for sure, but Irritrol web site may have cross reference parts. Soldnoid fit exacltly my my manifold valve. If you try to match with solenoid to another valve, it needs to match thread size and depth to seal the intake hole which opens the valve. so length of protruding arm must reach the hole. Hope this helps.
