This movement of armeture can be also done by a special solenoid (-densely coiled at up and low coiled down) And armeture will be made of FERROMAGNETIC substance..
You have added something that is asked in job interviews, "What is the advantage of a solenoid valve over the usual rotary valves? " Very helpful. Also, one can ask, "what is its disadvantage?" Lesics makes us think, not just watch passively.
You can't used it for high volumes too. You would normally need an actuator for high volumes. The solenoid valve activates the actuator and the actuator operates larger other valve (or rotary valve).
1.Requires electricity to operate 2.Generates a magnetic field (which may be undesirable) 3.Only binary output On/Off 4.(Probably) higher cost and maintenance
The rubber diaphragm can deteriorate over time or with contaminates in the fluid and let fluid pass through even it's off. It also needs constant power to keep the valve open unlike a rotary valve.
A really cool thing about the 5/3 solenoid valve is that the spool (or poppet as its called in my industry) is pressure balanced so there are no uneven forces acting on it from the oil!
As someone who studied this solenoid valve in my third year of Mechatronics Engineering, its satisfying to watch an animated version of the simulations and calculations we used to do in the Fluid Power course.
At 8:40 When Spool block oil, neutral position. in college I learnt that oil returns to storage tank from valve in neutral position In order to avoid damage to pump as well as valve. Thank you so much
Thank you for making this great video! This is by far the best explanation of the hydraulic system working with solenoid valves. Please make more videos of solenoids working in the hydraulic system. 10 stars out of 10.
Very clear explanation, it seems you have the magnetic poles flipped for the solenoid.The top of the solenoid near the spring is the South Pole since the magnetic field is entering the coil.This is at 1:36 in the video.
Watching this video I enjoy and can support the learning system in Vocational High Schools (SMK), thank you...success for "Lesics............"....Pekalongan, Central Java, Indonesia
Thank you for the demonstration Solenoids valve is new for me as coffee machine technician solenoid is too sensitive for hard water and easily stuckup and clog. Perfect demonstration thumbs up!
It has been a big question for me how the excavator's hydraulic system works.. now I got the answer.. this channel is helping me understand details of mechanisms
5:00 The pressure (on the left port) even helps seal diaphragm when the plunger is in the down position. THIS exact mechanism exists in some toilet tank fill valves too.
During the stop position of the valve the oil should be recirculated to the storage tank not stopped by the valve. According to your video the pump is running and the oil is getting blocked, which will cause the positive displacement pump to get pressurised.
Hi Lesics, you made a little mistake. The core cannot perfectly align with the center of the coils. This is because there is a spring, and so you need a continuous opposing force to hold it in equilibrium, so the core is always held slightly below the center.
The excavator uses a pilot pressure from a mechanically operated joystick supplied by a charging pump it pushes the back of sppol to make a passageway of the pressure from main pump to the direction of actuator
Very interesting video. I use these on a machine at work but they're for converting pneumatic pressure to hydraulic. As well, our dust collector uses diaphragm solenoids during it's cleaning cycle to pulse air into the filters.

Beautifully made video 👏 👏
Thanks for doing a video about this subject.
I always wondered how the hydraulic mechanism worked on an excavator
💖💖💖
Next video : how polariser film work.
Plz make a video on face recognition technology.
This movement of armeture can be also done by a special solenoid (-densely coiled at up and low coiled down)
And armeture will be made of FERROMAGNETIC substance..
I wish you could do more hydraulics, like pumps, motors and of course valves as well
You can check #lunchbox sessions they’ve a lot about hydraulics
But I want learn engineering
agree
*would
Yes please!
You have added something that is asked in job interviews, "What is the advantage of a solenoid valve over the usual rotary valves? " Very helpful. Also, one can ask, "what is its disadvantage?"
Lesics makes us think, not just watch passively.
You can't use it with very high pressures. (You probably could but unless you really need that timing component.. the dyafram would be too expensive)
You can't used it for high volumes too.
You would normally need an actuator for high volumes. The solenoid valve activates the actuator and the actuator operates larger other valve (or rotary valve).

Surely the way the fluid has to flow around must increase resistance, and decrease maximum flow.
The rubber diaphragm can deteriorate over time or with contaminates in the fluid and let fluid pass through even it's off. It also needs constant power to keep the valve open unlike a rotary valve.
The amount of hard work behind these concepts to made easy and those animations is appreciated 👍
I can watch excavator and hydraulic systems for hours. Hypnotic, relaxing.
A really cool thing about the 5/3 solenoid valve is that the spool (or poppet as its called in my industry) is pressure balanced so there are no uneven forces acting on it from the oil!
yes same with the example 1 with diaphragm.
This answers so many of the questions I've had like forever but never dared to ask...thank you Lesics for putting it so simply
As someone who studied this solenoid valve in my third year of Mechatronics Engineering, its satisfying to watch an animated version of the simulations and calculations we used to do in the Fluid Power course.
This video probably explained it even better, i had 0 clues of how this work, and now i fully understand it.
Thanks!
Wow lesics always amazes me with its brilliant videos
Díky!
At 8:40
When Spool block oil, neutral position.
in college I learnt that oil returns to storage tank from valve in neutral position
In order to avoid damage to pump as well as valve.
Thank you so much
Thanks
I recently learned about solenoid valves and I can't stop being fascinated
Thank you for making this great video! This is by far the best explanation of the hydraulic system working with solenoid valves. Please make more videos of solenoids working in the hydraulic system. 10 stars out of 10.
I cannot thank lesics enough for explaining suff of all sorts it helps a lot
I mean this wholeheartedly when I say this is my favorite video on TH-cam
Thank you. That helps me understand an collage lecture better I had this past spring.
absolutely fantastic! Great way of learning! keep the good work
Very clear explanation, it seems you have the magnetic poles flipped for the solenoid.The top of the solenoid near the spring is the South Pole since the magnetic field is entering the coil.This is at 1:36 in the video.
Doesn't matter. Solenoid will work regardless of polarity.
This is an example of an engineering marvel
Helpful video. Thank you.
Mechanical Engineer here: Brilliant video with great illustrations!
wow! I have learn a lot from this, thank you very much!
I love this video. U r doing a great job. Thanks man. Looking forward for more such videos.

I have always wondered about Solenoid valves. Thanks for the animation. Keep it up.
Each of your videos is so valuable.
Thank you for the demonstration Solenoids valve is new for me as coffee machine technician solenoid is too sensitive for hard water and easily stuckup and clog. Perfect demonstration thumbs up!
this is interesting learning solenoid , never know this could be soo interesting
This video is perfection.
Well, this is kind of the information I never looked for, but definitely glad to find hehe
If I am not wrong, for the hydraulic system 4/3 is preferred over 5/3. It does not need an external Tee for both outlets to the sump/tank.
This is brilliant 🤩
Thank you. My twelve year gets curious and I show him this animation and all of sudden he understands it. Versus me that that took years.
Your videos are dedicate, interesting and helpful. Thank you so much! :D
Thanks! It's very easy to understand through your valuable video.

Superb engineering explanation almost great 👍👍
Superb video brother
I like that video
During the stop position of the valve the oil should be recirculated to the storage tank not stopped by the valve. According to your video the pump is running and the oil is getting blocked, which will cause the positive displacement pump to get pressurised.
Thanks to say it. Please Lesics, explain more.
Solenoid valves always has safety oil on other side
Hi Lesics, you made a little mistake. The core cannot perfectly align with the center of the coils. This is because there is a spring, and so you need a continuous opposing force to hold it in equilibrium, so the core is always held slightly below the center.
This is negligible as compared to solenoid valves

Thanks!
Dear brother, if you have an Arabic translation. It might be better for us. As an Arab follower, I love. Your channel, thank you
Thank you!
Great video. Would love to see a similar version done on a distributor valve in a rail road air brake system.
I agree, that is beautiful
great video!
One day I will leave middle east and support this life changig channel. 💖
