Valve Solenoid Basics

Learn more on our website, with this session about Flow & Directional Control Valves: www.lunchboxse...
There are many ways to control the position of the valve spool. This week, we'll look at the solenoid - an energized coil of wire. It creates a magnetic field which moves the spool. We look at basic operation, maintenance, and what can go wrong.

[@ansariaqib]

How did you create this video and it possble to make it interactive?

[@lunchboxsessions]

Hi Aqib. We created this video with one of our custom built Live Schematic simulations. We've got over 190 simulations like it, and you can interact with them on our website. Here's a direct link to our session on Directional Control Valves, so you can see all the resources we have on that topic: www.lunchboxsessions.com/explore/hydraulics/flow-directional-control-valves

[@jasonevans1447]

I was beginning to wonder if anyone in the hydraulic world can just be straight forward... Faith restored!! 👍 Thanks

[@putci76]

Very informative video. Now I realize what mistake I was doing while trying to open a valve. I was bypassing it by keeping the solenoid energized !!

[@lunchboxsessions]

Glad it helped

[@joseacaciojunqueira554]

the best material for training, simple as possible.. nothing couldnt be better

[@Trudeautthebestt]

its wrong

[@lorenzop8022]

Just needed a quick refreshment and you delivered it perfectly. Thanks for posting!

[@Trudeautthebestt]

its wrong

[@David-uj2ms]

Great video! Very straight-forward and easy to understand.

[@uditsaxena3844]

awesome explanation i couldnt have understand it any better than you did sir

[@Wub892]

Epic fucking music in the background. I felt like an epic space battle was about to happen during this great educational video!

[@lunchboxsessions]

Thanks, haha. One of our programmers made that music. We've stopped using it in our newer videos, because we bought a better microphone and don't need the background music to "hide" how awful our sound quality used to be.

[@abdulrahmanmostafa325]

Perfect , thanks for your amazing explanation :)

[@rbalutps]

excellent animated video!

[@jjstelzig]

What would it indicate if you pushed both manual overrides and they both stayed pushed in? I have that problem on a autocrane crane. Will not scope in or out. Thanks. Your video is very clear to understand. I never knew how they worked but I get it now. Thanks again

[@lunchboxsessions]

Can you tell us what model of valve you have? It sounds as though your main valve spool is stuck (contaminants).

[@asamhatre2021]

when spool is in null postion, should we get oil in A and B, we have tested on Directional valve, we inserted 150 barg on P and we are gettingoil drop on Port A and B, is this normal in Null Postion without any command to Solonoide valve

[@stuarth43]

never too old to learn!! so, the de-energised valve returns until spring force?

[@malikaslam6912]

Wonderful .......Its very Nice video i would like to see more videos from you like that .. Thanks N keep sharing ..

[@kurzzmann]

Good video but please drop the background music!

[@Aaditya1008]

You guys are best in making simulation, can you post a video on yuken's MRP 01 reducing moduler valve.

[@vikipatange7306]

Hindi speech

[@Rask-s3y]

Great explanation , thanks for making this helpful vedio. 😊😊😊👍👍👍

[@peterrafeiner9461]

Why the distracting background audio? It's an educational video, not a music video...

[@Saidi-zd3ot]

How about the solenoids symbol can know the direction of push

[@madhumohan7765]

thank u ,will u plz keep a video on difference between the solenoidal and directional valve exactly and different types of valves and their workings

[@gregpartain4307]

What could the issue be if neither sides of the manual override works?

[@Teddy_Bass]

Little tip, If the override valve does not work, make sure the main nut is tight

[@gregpartain4307]

What other issues would cause a valve not to be able to be manually override?

[@Teddy_Bass]

@@gregpartain4307 they get rusty and seize up

[@nabilou8106]

Thank you, very interactive explanation, i've a recently changed 2 solenoid valves, because even if not energized, it keeps holding the pressure, and find it to hot, testing the ohm of the coil find it as the datasheet..any thoughts about ?

[@JL-tk7ng]

Really good video

[@farhadtorkaman6282]

in this animation , the oil path from the pump to the tank is not seen in normal position

[@Mech.Masters]

WHEN I OPENED A SOLENOID VALVE, I HAVE OBSERVED THAT THERE ARE SMALL GROOVES ON THE PISTON PART OF SPOOL. WHAT IS THE USE OF THOSE GROOVES? WHAT IS THE TYPE OF FIT USED IN SOLENOID VALVE BORE ID AND SPOOL OD?

[@InimaSenina]

hellow,please tell me if you know.I have a kafee maschine and during make a capucinno explosed e high pressure hose( this one who get in the solenoid valve ) i changed the hose and for a short time came pressure 3 sec and after this exploded again my ask is what can be broken ? solenoid valve or i have problems with hight pressure boiler? the watter ist warm...THanks Răspunde

[@BigBlockSpence]

I have a problem with a genie s40. Won’t steer because pressure won’t bleed off the opposite side of cylinder pressure is applied to. It has a similar type of valve, only solenoids are stacked rather than opposing. No one can figure out my problem. Steering valve and solenoids are new.

[@Mech.Masters]

In a hydraulic directional solenoid valve symbol, if there is a colored triangle symbol next to solenoid symbol then such valves are called as Hydraulic Pilot operated solenoid valves. But my doubt is how does a solenoid valve operate on Pilot pressure, it operates only when we give electrical signal to the solenoids. Kindly help me to understand this.

[@gotguns5]

I’m having trouble where the valve will work in one direction not not the other and even pressing the manual pin still will not make it work in the other direction

[@nadeemashraf883]

Heyy boss if it's possible you upload video how vaccum generated valve working. Thanks

[@rrebaza]

Hello, I have a jeep 2004 with hydraulic fan motor, with solenoide Valve to control speed. Seems the solenoid is not working. Can it be serviced, there are no replacements available. Or how do I try it, to discard a malfunction SOS please

[@engmctanaka]

Hi, your videos are very good, but do you have any video with proportional valves?

[@lunchboxsessions]

Thanks Marcelo. Stay tuned, we will make videos on proportional valves at some point.

[@Trudeautthebestt]

its wrong information

[@oscararredondo4523]

excellent explanation Could you control the output of the solenoids with a pwm signal?

[@Trudeautthebestt]

its wrong

[@santiagodiazortiz8926]

hi Carl, nice video, in which program you did the simulation??

[@raisedheart]

Santiago Diaz Ortiz it is in the description

[@lunchboxsessions]

We make them from scratch. Our animators draw the graphics in a vector drawing program (like Adobe Flash or Adobe Illustrator), and then write the the software code (JavaScript) that powers the simulation. The simulations run right in your web browser.

[@bhaumiks.6543]

Great video, just background sound is disturbing.

[@ouraacdazz9917]

Sir which solenoid valve is best for water wall graphics

[@powerbanknotebookchargingn4544]

where this valve mostly used in

[@CuongNguyen-pr3wn]

thank you very much

[@Raven4122]

My skid steer has one solenoid not working I switched the wiring and the wiring and the swapped sides on the solenoids (they are interchangeable) problem is definitely in solenoid do they ever stick and just need tapped to start working ot seems to be a sealed unit the replacement is $305

[@lunchboxsessions]

The solenoid itself is only a coil of wire - no moving parts. It can be checked with an ohm meter. If you mean that the entire solenoid valve is sticking, and only works when you tap on it, then there may be some contaminants that are causing the valve to jam. A new valve may solve the problem but only temporarily if the contaminants are still present inside the system/fluid.

[@Raven4122]

I replaced the solenoid and it works as it should thank you. SO im going to see if i can figure what went wrong with the old one..

[@workwillfreeyou]

Raven4122 I've done hydraulic work on heavy equipment and the dusty conditions were the root cause. Change hydraulic filters often! The systems are very sensitive to dirt. It's not something that can you can see. The oil may look clean and still be contaminated. Jim.

[@Raven4122]

Thanks for the advice jim I will take your advice and yes The new solenoid fixed my issue I will be doing a short video since I have found none.. Thanks again..

[@Estabanwatersaz]

Well done 👍

[@mojganloni9264]

What software?

[@amersyah7587]

How much?can i get it

[@sajjuch2188]

Perfect , thank you

[@huylehuy4166]

thank you for an amazing video. can you tell me what is the simulation software?

[@mayoogaganeshan5982]

Very helpful thanku sir

[@GLADYATOR109]

awesome video thanks what program do u use by the way

[@lunchboxsessions]

We don't use any program - we make the simulations all by ourselves. You can read more about them here on our company site: www.cdiginc.com/live-schematics

[@GLADYATOR109]

LunchBox Sessions the link doesn't work. what i mean is which program do u use to make these simulations they're realy awesome

[@lunchboxsessions]

I'm glad you like them! Our team of artists/animators/programmers draw the graphics in a vector drawing program (like Adobe Flash or Adobe Illustrator), and then write the the code (JavaScript) that drives the simulation. The simulations run right in a web browser, like any web page. Thanks for pointing out the broken link - I've edited the comment and fixed the link.

[@GLADYATOR109]

[@D_J_R_S]

you guys charge more for your hydraulics course than the actual IFPS charges for online courses.....and with IFPS you get a hydraulic magazine subscripfion. nice website but cut the price by 75%

[@lunchboxsessions]

Ivan here - I edit the videos, and I'm the lead programmer on the LBS website. Allow me a moment to explain some of the value difference between our site and the IFPS courses, since that might help explain the cost difference. We share a common goal with IFPS - to help people learn, level up their skills, advance in their careers. If you look at the details of our pricing vs. theirs, you'll find we each cover a range of price points. Their courses cost $299 for non members, or $99 if you pay a $75/year membership. We charge $249 per year for access to our whole library, but you can also snag individual sessions for as low as $15. So it's much cheaper to get started with us, and our most expensive price is less than their most expensive price. But I think the biggest difference is in the value of our content. We have software developers and 3D animators on staff, constantly working on new types of simulations, interactive animations, games - all sorts of things. Our latest content works in every modern web browser, on every platform (including smartphones), and we're constantly reworking and improving our back catalogue, every year. Our content library today is crazy polished, but it's going to get so much better over the next few months (we've got some big upgrades in the pipeline). A subscription to our site provides ongoing, increasing value. Yep, the IFPS magazine is ongoing value as well, but it's not laser-focussed on helping you learn skills, so it's orthogonal to what we offer. Apples to oranges. At the end of the day, if you like the IFPS courses, and if you feel like they're good value for the money, that's fantastic. We just want people to learn as much as they can, no matter how it happens. For the people who appreciate what we do, I think we have tremendous bang-for-your-buck value to offer them.

[@D_J_R_S]

LunchBox Sessions cool. Your vids are of excellent quality and with the membership it ends up comparable to IFPS. I didn't see the membership bit before I ran my mouth. I apologize. beautiful website btw

[@chatclick8974]

Tu l’aurais mis en français j’aurais mieux compris

[@johnwilliamson2393]

When trouble shooting electric over hydraulic, always pull the coil off the valve stem and verify its clean in between coil and valve stem, and that stem is not slightly bent. Both can be a real showstopper, and turn up in equipment regularly.

[@TheDollarProducer]

I like how clear and slow you explain this material to the viewers. It definitely an effective way to enable us in order to understand the video clearly. Good Work.

[@Trudeautthebestt]

thats wrong ...thats wrong...thats wrong..thats wrong....when the solenoids get energized it pulls not push ok unless video

[@peterevans7480]

How do I get a log in to your sessions on your web site? I have logged my interest by no reply.

Hi Peter. Thanks for registering. LunchBox Sessions will be open to the public soon. We'll email you when the time comes. Until then, enjoy the KZbin videos, and let us know what topics you'd like to see covered.

[@petersalimkumar1192]

good presentation .

[@Daniel-nf2ku]

Can these solenoid valves be actuated in such a way to feather the hydraulic flow by using a rheostat or are they only able to be operated fully open or fully closed?

Hello, could you tell me why 4/2 way valves stopped being produced and replaced with 5/2 valves?

[@عبدالناصرمحمدحميدالربيعي]

❤ممتع

[@jenniferstelzig6779]

That's what it was. Cleaned and it's working perfect. Thanks alot

[@lunchboxsessions]

Oh super. Glad you got it figured out. If you had some dirt or grit in the valve, and you can figure out how it is getting into the system, then you could prevent it from happening again. Typical points of entry include filling procedure (dirty pail and funnel), low quality tank breather (it's worth it to get a high quality one with a desiccant for moisture control as well) and scored/scratched cylinder rods among others. - Carl On www.fluidpowerworld.com we did a two part webinar last fall that you can still download and watch re: contamination. www.fluidpowerworld.com/webinar-dealing-contamination-sources-hydraulics-part-1/ www.fluidpowerworld.com/webinar-dealing-contamination-sources-hydraulics-part-2/

[@yusufsayyed1]

how its operated in one solenoid with two functions?means one directional valve have four function like outrigger beam cy,extend and retract,and other outrigger jack cyl.extend and retract.pls described

[@lunchboxsessions]

yusuf sayyed it sounds to me like you are describing a circuit that also has a sequence valve (no additional solenoids). Either that or it is simply a matter of two cylinders in parallel and the one that is easiest to move (lower pressure) goes first.

[@sixpackguy3000]

Hi, Can a faulty Pressure Control Valve, of a diesel car's fuel injection pump, cause hard starts in the mornings ? You see, I've checked almost everything else (battery, starter, glow plugs, EGR, MAF, etc., etc.) and all working well. The hard starts only happens in the morning, I dont get hard starts throughout the day, not in between trips, not even between short trips. Hope you can help. Thanks in advance !

[@pvtimberfaller]

Usually they just quit in my experience. Do a compression check.
