Piece of cake
We have a yard full of Irritrol 205 valves. 13 zones to be exact. All are 20+ years old. One finally went out, with the zone staying on. Changed the diaphram but still had trouble, so bought a new valve and replaced the top, including solenoid and insides. Problem solved. Easier than just replacing the diaphram and cheaper than buying all the parts individually and making repeat attempts to fix. I bought several to have on hand when other 20+ year old valves start to go.

Works great, good price.
My local shop would sell just the solenoid for more than this price for the whole thing. So bought the valve and installed it with good results. One note - two day shipping does not mean it will arrive in two days. Ordered on a Thursday and it arrived Tuesday. .

Could not be more pleased!
With all of the detail on your website I was able to find the exact replacement I needed. The prices were excellent and the product shipped quickly. It arrived in good condition and I swapped out my original piece with the new one and it worked perfectly the first time. I could not be more pleased.

Irritrol 205 valve
The valve worked perfectly in replacing an old valve that wasn’t made anymore. The local sprinkler company wanted $800.00 to replace the whole manifold because they didn’t have an old valve. $18.00 bucks sounds a lot better than $800.00!! Thank you sprinkler warehouse!!

I have an older model Irritrol 205 series valve. Actually, I have 24 of them. One valve is STUCK in the on position. I can't turn it off. I have taken it apart (in place) and thouroughly cleaned it, replaced the solenoid, and inspected the diaphram for any problems. It still stays on! I am at my wits' end. What now? the base of the valve is fine. It was working just fine before this excessive heat spell. I am on well water and yes, there was some sand on top of the diaphram membrane even though i have a sand separator. The aquifers are so low that my pump was sucking a lot more sand than ever. What are your thoughts for this station #12 valve?
Bruce K on Sep 6, 2011
BEST ANSWER: I had older model 205 series valves as well when I moved into my house but they were all in disrepair so I ordered the the 205tf and took the new components off of the new 205tf valves I got and put them on the old bases. They fit fine but you have to be careful everything lines up if you want them to work and not leak. The 205tf has a manual shut off so even if it does not fix your problem you should be able to shut the vaulve off manually by tightening the flow adjustment screw. Hopefully that helps.
can i replace an old richdel valve with the parts from this irritrol with flow control if there are 8 screws in the bonnet?? Ray
Raymond A on Jun 17, 2012
BEST ANSWER: Really can't help with this. Have not used Richdel valve.
My suggestion- go ahead and get new Irritrol valve and try
it. Fine if valve top is interchangeable. If not, install
full Irritrol valve. Extra work but probably necessary. I
have found that buying valves locally is a problem as stores
seem to routinely change the brands they carry and several
of the brands I've used over the years do not have
interchangeable parts. Good Luck!
do you have with 120 vac the same 205 tf series?
Assadollah j on Feb 2, 2015
BEST ANSWER: All the sprinkler control valves are 24 Volt (DC I believe). You would have a big safety issue if you were running 120V out to the valves. But, all the sprinkler control timers typically have a transformer that powers them. So, your controller will just provide the power that's needed to operate the solenoid in the valve.
what does tf mean ?
A shopper on Feb 9, 2012
BEST ANSWER: I believe that the T and F stand for two different things. The T is for threaded (verses slip) and the F stands for flow control. Note that there is a 205SF model which is slip on with flow control.

Hope this helps.
What is the coil voltage for this valve?
A shopper on Nov 8, 2011
BEST ANSWER: its a standard low voltage unit. Had problems with my order tho and the sprinkler warehouse blew me off. Think twice about using them. I never will again
What will this regulate down to? I have an application where I need 2 psig at 1 gal/min. 5 to 25 psi on input.
Larry B on Dec 11, 2016
BEST ANSWER: This one will only go down to 10 PSI minimum input, and at that it will do 1/4 GPM minimum. So this would not work at the lower end of your requirement with any consistency as far as I can tell.
I have a 205 irritrol valve, the solenoid is 24 v, a new intermatic timer was installed 120 and 24v system. the solenoid is working fine, however the water flow seems not strong enough to tun on the zone. I used the screw to bleed the valve to turn on the zones and they come on. What could be the problem?
Luis R on Mar 18, 2015
BEST ANSWER: i was asked if I could answer your question. Sorry, I don't know enough about the operation of the 205 to help.
I have Richdel R-204 flow control valve, is this the right one to replace it? Thanks!
John W on May 26, 2014
BEST ANSWER: Any flow control valve will work, just make sure it has right connections. Meaning male or female for your type of installation you need.
Hi, Is it possible to buy an extra solenoid for this valve?
ed b on Oct 19, 2011
BEST ANSWER: Yes, they are available on this website


Please note that this for the 24VAC coil ..not the 110 volt coil.
Just be sure which voltage valve you have or are getting.
Is there a difference from 205sf & 205tf solenoid valve?
A shopper on Jul 27, 2018
BEST ANSWER: I bought the 205tf as a replacement for the old 204. It works perfectly! The repair company wanted $800.00 to replace the manifold with 4 valves because the 204 isn’t made anymore. What is the difference between the 205 sf and 205 tf?
I was told to get 4 205T valves. Will the 205TF work on my system?
Also I have ordered an indoor 4 zone time and a rain sensor. Do these parts come with all the necessary clamps, fittings, wire and waterproof connectors? If not what what will I need to complete the conversion.

diagram for 205TF valve?
A shopper on Jun 13, 2014
Have a six zone system 205 sf valves that hasn't been run in 7 yrs and the controllers shot. Need a reasonably priced controler that dependable and simple to use. Also a friends who claims to know something about sprinklers got two zones to operant be by passing the solonid but the wouldn't shut off. Don't want to cut the whole thing up. What should I do next? If I need to replace the valves can I get nen valves leave the bottoms and replace the tops. Thx
