inside a cheap eBay solenoid water valve.

[@LakeNipissing]

Absolute perfect description of a pilot-operated valve (for either pneumatic or hydraulic). I work with solenoid valves, pressure regulators and pneumatic relays on a daily basis, and you nailed it with a very easy to understand theory of operation regarding pressure differential on either side of a diaphragm.

[@manuchaudhary7902]

Hi Lake, i need a few solenoidal valve for controlling the Waterflow through pipes. Can you give a link to purchase it in USA?

[@roberthorwat6747]

I remember Tim Hunkin explaining this incredibly clever device on The Secret Life of Machines circa 1986. I had in fact forgotten about the actual design of the diaphragm so this has been a nice revision session for me. Thanks a lot

[@RogerAllisonJones]

Oh yes, yes, yes! That whole "Secret Life of . . . . " series is burnt into my memory. The junk yard, the dirty fingernails, old frayed tweed jacket, taped up specs, . . . incredible. Remember him cutting the metal in a Morris Minor bonnet with a pair of scissors? I wonder if Clive has ever seen the shows? They're on KZbin, not to be missed.

[@JayFe0]

Thank you for sharing that video. It serves to remind me just how ignorant I am despite a fairly broad, but shallow, understanding of biology.

[@al50481]

Robert Horwat Secret Life of Machines was my favourite TV programme when I was a boy. I wrote to Channel 4 about 10 years ago and asked if they would repeat the series but they said no. You can however download all the episodes online :)

[@roberthorwat6747]

Roger Allison-Jones I actually got the opportunity to repeat the scissors cutting steel thing as an employee of Honda some time ago. Just a cheap pair of office scissors through some scrap panel pressing and I cut it right in half. It took a fair bit of effort though but I was just as amazed seeing Tim do it as trying it for myself. Before they uploaded the entire lot of programmes onto you tube I downloaded every single episode from the website so I have the full set. Fantastic show!

[@roberthorwat6747]

al50481 I downloaded them all as soon as they became available. Now on youtube though, whenever I show them to someone I get the same reaction every time. Wonder, amazement, fascination. The seemingly complicated very simply explained. Tim & Rex are all time heroes of mine

[@shawnkerr291]

Spot on tear down. One item of note to those interested, don't ever activate a coil like that with nothing in the centre, the magnetic field created can actually burn the coil. At the very least run a screwdriver up the centre for testing purposes. I stumbled on your channel a couple of weeks ago, absolutely loving your content.

[@bigclivedotcom]

That characteristic smell you get when you're working on refrigeration plant and someone has left a solenoid coil off it's base....

[@pnjunction5689]

Spot on with spring! Its purpose is to clean the compensating port and it's patented by the company I happen to work for :-) Btw. very nice explanation of the servo mechanism!

[@WaltonPete]

Modern toilet cisterns have fill valves which work with the same method - it means the float can be much smaller as the force required is less than a traditional ballcock and valve assembly which equates to smaller, neater cisterns.

[@aezram]

Your discussion and drawing were very elucidating, many thanks Clive. I construct irrigation systems but haven't yet had need to service a valve interior, and so wasn't aware of the clever force multiplier effect of the diaphragm. I've confirmed that the landscape grade valves I use operate on this same principle (although the solenoids actuate on 24VAC, presumably because of the long cable runs required). I'll have to order a couple of these cheapies to play around with for toy aquaponic systems and the like. Come to think of it, I wonder if the valve may not positively close under low pressure intakes, such as gravity feeds...

[@larkhill2119]

It has been designed for low pressure which is why it has the extra spring. The important parts are the quality of the rubber and type of steel used in the plunger so it just not rust and jam. Same quality as used in you washing machine at a fraction of the price. but 230/110 volts Ex Factory FOB prices are around $1.50 -$3 on a lot of brands. If your lucky have a look on line you may see the same brand with a different fittings, and just change the inside round. Failure to fill fast is normally a small hole in the rubber part keeping the valve closed. Most were made in Italy a few years ago.

[@Razeth]

not in a bad way, a good way, but your videos are so interesting and soothing that a lot of the time i fall asleep watching them lol

[@Cavalier_Steve]

Razeth yeah it makes me sleepy to, so soothing!

[@mirkomueller3412]

Now i finally really understand how this works. Thank you very much !!!

[@jackking5567]

Agree with others here Clive that these are are common in washing machines where feed pipes fix to the rear of the machine itself.

[@SpiderTalon]

I hooked up one of these to a momentary switch on my Keurig to refill the water reservoir. It works great, but you are correct that it has a small delay to stop the flow.

[@justbellavista]

Hi Clive, this is fantastic. We have 2 x 12volt solenoid valves on our boat toilets to control the flushing water. These have been a pain of my life for the last 10 years as they are always leaking when the small transfer hole blocks. Thus the water ends up continuing to flow and flooding over the bowl. That little tag on the spring to keep the hole clear is such a simple idea. My valves are made by Jabsco and cost over £100 each. I will be order 2 of these plus 2 more for spares asap. Thanks for the tip. I will post a video of these being fitted and a link to this video on our channel. PS Thanks for all your videos they provide endless hours of entertainment and information for us fellow geeks! 🙂

[@Neffers_UK]

Cool, thanks Clive. Been looking at these (among other solutions) for an auto watering setup for a friends allotment. Nice to see inside of one before deciding.

[@paullewis1637]

I am thinking of using one of these to water my hanging baskets via a remotely operated hand control. Anyone out there done the same. I would value your reply and comments.

[@hassanburrows8535]

Hi Clive, I think if you listen carefully to these valves in action on the job, you can actually hear that brief pause as the pressure equalisation is taking place on both sides of the diaphragm when the valve closes.I think it may be a requirement of the water regulations that an instantaneous water shut off on a main is to be avoided to prevent water hammer. The concussive shock can be quite considerable. Keep carrying on!

[@joinedupjon]

Oddly enough my old electronics teacher gave me the first explanation of these ingenious valves - I think the context was an automatic bath filler with temperature control. It never happened - we couldn't find low voltage ones at a reasonable cost...and tbh the idea was a bit rubbish... I'd fancy this for greenhouse applications or perhaps a PIR operated anti-cat watercannon.

[@phils4634]

Built an "automated" watering / misting system using near-identical washing-machine valves decades ago. Two valves, and a pair of bimetallic strip thermostats, along with a simple 556 timer circuit and a pair of relays to handle the 240v for the valves. Built it in 1985?? Still works just fine . . . . . .

[@joinedupjon]

Phil S Yeah - that's the same period. we could get scrapped 240V washing machine valves cheaply enough but we weren't allowed to make mains gear in school. Thought about handrolling low voltage solenoid coils but then I went off the idea anyway.. There was a nearby shop that specialised in scrapping old industrial control panels and you could get some super relays, transformenr panel switches and stuff... FWIW timer based watering systems are on the way out, you can buy ones you can control from an app on your iphone - so even on holiday you can busy yourself with domestic chores.

[@phils4634]

joinedupjon The "old and simple" approach works fine, especially where fault-finding is concerned! The "watering" side was not thermostat controlled - that was a standard "water for x minutes then stop" which seemed to work OK. The two 'stats ran the mister, a cheap bathroom extractor fan, and a solenoid / spring control on the roof vents - I had a BIG (10 x 8) greenhouse and in the summer months, it "needed a little help" with temperature management :-)

[@phils4634]

I'd not be surprised if that Brass was DZR brass - allowing for variation in monitor performance, the shade seems "just right". The inline filter is a nice extra too - not particularly fine, but obviously someone's thought about this, and the end product is all the better for it. Chinese quality is RAPIDLY improving, and I'd expect the same transition in perception as we saw with Japanese cars - originally poorly-regarded, now the Industry standard.

[@phils4634]

New notepad too? Plastic coil vs. your "usual" spring coil? If those self tappers pull out Helicoil them - a far better fixing method, and (because of the finer thread) a much tighter grip.

[@locouk]

You explained it really well, I wonder what the maximum pressure that it can cope with is?

[@Coolkeys2009]

I don't think I 'd trust that on mains water pressure.

[@Strider9655]

Mains water pressure isn't really all that much, it varies from around 2 bar to 6 bar, but if you have mixer taps in your home you should be using a PRV to regulate the pressure to around 2.5 - 3.5 bar (or you get leaky taps). A valve like this one would have been designed with industrial use in mind and should be able to handle more pressure than a domestic supply would be capable of. Before anyone bangs on about turning down the stop tap, it's important to point out that pressure and flow are entirely different, they're like voltage and current.

[@Strider9655]

***** See that's what I mean, that's not a pressure problem it's a flow problem. Pressure only exists when the taps are closed and the pressure equalises to the external (to your property) pressure. If you put a pressure gauge on your system and almost fully close the stop tap, the pressure will remain the same as when it's fully open, but as soon as you open another tap you'll get a burst of water, which will then slow to a trickle because the flow is obstructed at the stop tap.

[@Coolkeys2009]

Strider9655 I've seen pictures of metal taps blown off by mains water pressure and people's boilers burst and flood because of it. The self tapping screws holding the fittings on looks like a point of failure.

[@Strider9655]

Coolkeys2009 Not sure what your getting at, I mentioned the use of a PRV, having one of these would prevent most if not all instances of what you describe as it totally isolates the internal plumbing from the outside water mains.

[@mrdovie47]

I use a lawn sprinkler valve to turn off all my water in the house until I need it. My water system leaks everywhere and I can't afford to replace it. So, rather than let the house be destroyed and my water bill go to extremes, I put the valve on my water intake. It has worked for several years, now.

[@UNTBC]

the springy thing on the valve and stem is a anti hydrolock feature.

[@kevito666]

I was going to say that, too

[@TheBushdoctor68]

Saw the thumbnail, thought someone invented the smallest flushing toilet. Dang.

[@leplum2001]

That solenoid valve looks almost identical to one I replaced recently in a truly cheap and nasty Montpelier washing machine. The coil had gone O/C, I didn't investigate the reason.

[@bigclivedotcom]

The coils do fail from time to time, particularly in machines with built in dryers that use a small flow of water to act as a condenser.

[@khaitomretro]

+bigclivedotcom It looks cheap enough to upgrade the coil with something longer lasting (boiler gas valve coils, both low voltage and mains, that should last for a decade) and still be cost effective. The bypass washer is a cheap replaceable component too. They last for many years in toilet ballcocks working at mains pressure.

[@khaitomretro]

+simontay1984 If the machine vents to outside, but if it just recirculates air it has a condensing plate or coil which used small amount of cold water to condense the water vapour.

[@bigclivedotcom]

+simontay1984 In some of the combined condensor dryers where the moisture from the drying clothes is collected and pumped out via the drainage system, the cold water supply is used to provide a low level trickle of cold water to cool the condensing surface. In the case of the early Hotpoint units it was just a channel down the back of the machine with a felt pad that had a continuous trickle of cold water running across it. Horribly inefficient and failure prone machines. Particularly the solenoid valve for the condensing flow as it would remain energised for the full drying cycle.

[@bigclivedotcom]

Dedicated condensing dryers are a much better option and do at least put out their excess heat into the room. The combined washer dryers are just not really a good idea in terms of the drum size and technical complexity.

[@rtesimpson]

yeah you could use it with an Arduino to make an automated watering system

[@SurajGrewal]

tried using these valves for airgun, found out that slightest hit to it could lead to actuation of the valve, thus rendering the gun unsafe whenever the reservoir is inflated up

[@scifactorial5802]

What pressure did you test them up to? At what point do they leak?

[@SurajGrewal]

under 40psi when hit,it leaks,above 45psi ,18 volts is unable to open up the valve

[@qwertyasdf66]

Damn. I half built a nerf gun mod which revolves around exactly exactly this concept. On one hand you saved me the time i would have wasted on finishing the project before discovering it was fundamentally flawed. But on the other hand i still wasted a bunch of money buying all of the components and ruining a perfectly good nerf gun : (

[@qwertyasdf66]

I wonder if the issue could be solved by increasing the strength of the spring that pushes the diaphragm down.

[@SurajGrewal]

tried it, even 40 volts can't open the valve, hitting it still opens it.

[@n2n8sda]

I use one very similar connected to a raspberry pi that also has one of those soil moisture probes connected to it. didnt trust it on a mains fed water supply so it controls a gravity fed water tank that collects rainwater. Built it to keep my cucumbers watered in the summer but by the time I finished it the summer was over.. always next year...

[@christheother9088]

I thought these things worked like gate valves but there is a lot more going on. Elegant.

[@whisthpo]

Enjoyable and revealing vid again Clive! I actually have an interest and book marked a few of these in my Ebay 'watch list'. My friend who has finished (unlike me) his van/motorhome conversion, uses one of these to remotely dump his 'grey' water tank which, I thought was a very cunning idea! Thanks for the education of its internals!

[@ItsAlwaysRusty]

I Wouldnt want to put much pressure through that.. It would blow apart.. I second the request for a work bench tour. Would be cool to see. Take Care..

[@jusb1066]

i would say its probably aluminium bronze, its both cheaper to make than brass and has good corrosion properties.

I am a programmer. And now I know how solenoid valve works. Thank you! Subscribed. PS: oh wait, what am I doing?

[@el737rs]

Great explanation. Just to add - no wonder there is a filter and no wonder it is easily serviceable, because (I guess) in case of water not being perfectly clear it could easily clog those tiny holes.

[@warmtepompdokter]

[@tonybaines3332]

there very good to use with a timer circuit as an automatic garden watering system for summer, ive done one in the past

[@dashcamandy2242]

1:10 - KHAAAAANNNNN! Sorry, I had a Star Trek moment. ;-) It seems cheap enough that one probably would not want to disassemble it... And inexpensive enough to not bother rebuilding them if the diaphragm fails, just replace the whole unit for a few bucks. It is, however, a nice little unit to have for a clothes washer water inlet replacement if the original fails... I could also see it applied for light-duty irrigation, hydroponics, water features, even for DIY heat pumps. Quite a nice find, Clive!

[@DarkAvatar1313]

You could make an auto dog water bowl filler with it having a weight sensor on a mat the bowl is secured to turn it off when the bowl is full or when the dog is present.

[@68000Mark]

I use one of these solenoid valves connected to a ZJ-LCD-M flow meter on my brewery (real ale). I use it between the HLT and mashtun so I can measure the volumes of water. Works well most of the time but not and again it stops, I think the water gets too hot as the valves are rated at 80 degrees C maximum.

[@MickeyD2012]

I can think of a few very useful applications for this.

[@marhar2]

Great explanation of how the diaphragm works, thanks!

Very Cool Teardown Clive. Keep up the great work. Nick.

[@MorpheusXTRM201]

That device could had been used for a timed sprinkler system to water the lawn or a garden system similar to what some grocery stores would use for spraying mist on vegetables.

[@jeremyvoshage2410]

Do gas valve diaphragms operate in the same fashion??

[@thagrit]

I can't find that particular solenoid valve on ebay.

[@tohopes]

I tried using a solenoid valve like this to control a bucket-fed drip irrigation system, but it was a total fail because these valves require a certain amount of water pressure to work, and the bucket's few feet (less than a meter) of height was insufficient. Looking at your dissection, I guess that's because low water pressure is unable to press open the diaphragm. A motorized ball valve (off eBay) did work for me. They're more expensive, but would be cool if you could tear one apart some day.

[@michaelshultz2540]

The solenoid changes the water pressure from one side of the diaphragm to the other pushing it open or closed depending on the position of the tiny pin . This works exactly like a washer inlet valve. I have taken many apart and cleaned them when they either dond open or close compleatly ; ( usually what goes wrong with them in washers. Why replace when if you clean out the grit they work like new again , provided lightning or a power surge has not killed the coil ; which could only happen if it was activated at the time of the over voltage . Very unlikely.

[@ironknobsteelworks4063]

Wired up so many of these solenoids, now i know how they work. cheers!

[@danielson101]

water might push open and coil shuts off?

[@justblairthompson]

That diaphragm looks very similar to the one I have to replace on the inlet valve to my toilet cistern (every few years). I never understood how they worked... I just about get it now, but I think I will have to watch this video a few more times.

[@collinhunter9792]

Did I miss something? Is it connected to the mains power through a power adapter? And how does it know when to go and stop. I'll have to watch again

[@SlyPearTree]

Would any solenoid valve be ok for drinkable water or do they make special type for that? I'd use it to fill a coffee maker with water.

[@bigclivedotcom]

As long as any simple valve like this is flushed though with clean water I'd think it should be OK. Many drink vending machines use solenoid valves like this for controlling water flow.

[@madmikeybaby]

bigclivedotcom Hi Clive, I bought one and put it in the pipe to my bath filler. Fitted a 10 minute mcu timer to control it and use an arduino with a bluetooth module and proximity detector so now I can fill my bath with touchless 'swipe' or from my phone. And it shuts off so no need to keep an eye on the water level. I really must get out more! Keep the great vids coming. Love 'em!

[@lukenfoci]

No. Officially anything for potable water needs to be WRAS approved. Similar, WRAS approved solenoid valve costs about 10x the one shown in example above. However, build quality is 10x superior, so well worth the money.

[@poiiihy]

valve should probably be made of drinking-safe materials and be drinking-safe, otherwise might not be a good idea

Over-tight pistons would not allow him to turn off the engine. Sounds like him and acts like him. If you have not seen the film, you must! Utterly hilarious.

[@VitorMadeira]

Excellent video. Do you know if those kind of valves can be used in a low pressure water system? I need to control the out of an IBC water tank and this might handy, but I'm afraid the water pressure would not be enough to make it fully operational. Thank you.

[@TheDefpom]

I wouldn't want to put too much pressure on that thing, it would rip the screws out of the brass ends.

[@larkhill2119]

I have only seen a glued in one fail. There would be millions of screwed in ones all over the world. If the outlet has any pressure on it the valve will close the inlet is only a small area so PSI is low.

[@robertvanderzaan9681]

I want to see you use it to make a pulsed fountain display !

[@PixelOutlaw]

Would this be fast enough for a pneumatic potato gun quick release?

[@jackwhite3820]

Well, pilot operated valves are generally slower than direct operated valves, but direct operated valves with high flow rate will be more expensive.

[@jamesward408]

PixelOutlaw not sure about potato canons, but I've used this exact same valve in a compressed air rocket launcher, and it works well in that application (launch tube is 15mm copper pipe and the rocket was made of foam pipe insulation)

[@Nigel_Broatch]

Out of coincidence I've just fitted one of these to the inlet of my loft tank (in series with the ball valve), I'll let you know how long it lasts.

[@FontediCalore]

Thank you for the explanaion. Now I know why they don't work unless there's lots of pressure. I need to open and close a tap that has no pressure!

[@FaithsFallen]

Fantastic explination of a solenoid now i know why my washing machine makes a massive thud in the pipe as it stops water entering.

[@Graham_Langley]

You can get small (

[@superdau]

Do you know a kind of "fail safe" valve that restricts water flow if a pipe/hose would burst, but allows normal flow for a short period of time if there wasn't any flow for some time?

[@markrainford1219]

Google aquastop.

[@RobertSzasz]

mark rainford aquastop seems to be a hose in a hose shutoff. if the outside hose gets pressurized it trips a one time valve. Something smarter that just looked for flow or no flow, and shut a valve after x minutes of flow would be best. (a fire sprinkler flow detector, a delay relay, and a electrically trippable valve could be slapped together to do what you want)

[@markrainford1219]

Yes, they also do mechanical only or electrically operated valves that detect abnormal flow rates.Robert Szasz

[@RobertSzasz]

mark rainford the problem with those is that "abnormal flow" includes opening a valve all the way to fill a bucket or similar high flow uses (refilling drained water heater). Having a way to automatically shut the water off if there is either a high flow for more than x minutes, or low constant flow for more than y minutes would be nice. I havent seen anything with a time delay for high flows, or time delay with checking for constant flow rate.

[@markrainford1219]

Robert Szasz Just looked at details on their website for the Aquastop YS mechanical only. You set the variables time/flow rates on installation, so you set them for what is normal for your situation. It also detects pressure drop across the device. I've never fitted this type, but i've fitted many of the hose-in-hose type, mainly because they are standard fitting on many high-end white goods.

[@CarltonDodd]

That filter would be critical to continued operation. If a bit of something gets embedded into the diaphragm, the valve might never shut off!

[@larkhill2119]

Normally the only part to jam them is the filter breaking. Mostly caused by rust on the plunger jamming. Some German washing machines have a mechanical device that unwinds and cuts off supply if water has been flowing to long.

[@TimGremalm]

"The diaphragm has a pinhole through its center which allows a very small amount of water to flow through it. This water fills the cavity on the other side of the diaphragm so that pressure is equal on both sides of the diaphragm, however the compressed spring supplies a net downward force. The spring is weak and is only able to close the inlet because water pressure is equalized on both sides of the diaphragm." en.wikipedia.org/wiki/Solenoid_valve#Internally_piloted

[@ThatGuy-nv2wo]

But...Does it work now?

[@maicod]

+That Guy no but it does blend though

[@bennydelacruz1779]

Does this water solenoid valve require water pressure to operate the closing and opening of the valve? Thanks

[@bigclivedotcom]

In a way yes. It works by equalisation of pressure on both sides of the diaphragm.

[@terkfranks1538]

Still watching... but did you mistake inlet for outlet... seems like the inlet would be before the shutoff mechanism and the clean out would be after the shut off mech and before the outlet... back to the video lol

[@DoRC]

Entertaining as always. Question, i was looking online for a atx power adapter that would allow me to go from say the 12v rail and be able to adjust the voltage and current. I know about the little dangerous prototypes board as well as the little boost buck converters but i cant seem to find and dont know why just a box that you plug the 24 pin into and has those adjustments built in.

[@HelenaOfDetroit]

I wonder if you could create a system with 2 of these, and an arduino, that would let you remotely turn on and set the temperature of your shower. You could even set it up to an alarm, so the shower is ready the moment you are.

[@larkhill2119]

One of the valves would have to be proportional F&P New Zealand used to have a 24v one a few years ago but if you have any water hammer you need an anti hamer device as well. The aluminium tube with the heat sensor was used to cool the motor triacs as well. Then when it corroded it was not a nice ending with 310v DC .

[@Sedokun]

Those have a long time of "relaxation" (i.e. closing). It also became worse over the time due membrane tear down (depends on water quality/pressure/temperature). Same valve is used in almost each modern toilet inlet.

[@LUCKY007725]

Hey Clive, did you fit that central heating water filter from your video a while back? Curious to know how much crap has collected inside if you'd consider revisiting it?

You missed out on the "easy to remove and clean FIlter".
