Currently in school in Quebec in electromechanics and these videos are a life saver. Thanks for taking the time to post these to youtube, very informative! Going to share them with my class for sure.
I am a Asian Chinese. This is my first video training program on pneumatic or (as it is quite similar to) hydraulic system, I am able to understand entirely with just 1 run. It is very motivating to learn more from you. Great job!
Well, I had struggled whole semester to understand this however I wasn't understood it fully. And look today, I saw your video and Boom!!! I learned it in 15 minutes. Thank you very very much.
He is one hell of a teacher usually hard for me to retain or recall what I've read or what I've heard his ability to keep your head in the subject as a whole and not just Parts at a time is amazing he has to be good I've never commented on anyone before thank you best video I've seen by far
Very good teacher. Let’s say you want to automatically apply power to the control valve and have the cylinder keep retracting and extending. Will I need a limit switch at each end of the stroke and a linkage rod connected to the limit switches?
this is very understandable. ive never seen anything about metering ever, and i knew exactly what was happening by the time you got to the real life set up. and props to whoever made your magnetic marker board visuals. they are the mvp in this lesson. of course the guy talking helped a little bit...har har. (j/k)
You explained it clearly sir, esp those movable board demo. Well explained. You are truly a very good teacher to us. You really helps us. Thanks for this.
Hello sir... Can you tell me Variable flow control valve is two... Means does it allow flow in both directions unlike check valve which don't allow in both directions...????
I have a question, does the metered fluid pass through the pressure relief valve back to tank. For the cylinder to move slowly with a positive displacement pump i would assume the excess fluid from the pump would pass through the pressure relief valve? Also amazing video!
The best video I watch about meter in & out circuit! All the basic concepts are covered & it really helped me to understand those confusing speed control circuits. Thank you 😃😃
@@KletteTech sir it's seems that you have a very good knowledge about pneumatics and Hydraulics so i request you to please making video on types of valve and it's applications.
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 !
One question sir? Wouldn't the oil go through the check valve and back to the speed control and solenoid valve as ones as you go meter in? just because speed control outlet port is connected to the check valve exhaust port. Please 🙏 explain. Awesome video and explanation though. Thank you sir.
Hi, thanks so much for breaking this down. At my school we're using amatrol which is great at times, but I feel they make the pneumatic and hydraulic concepts overly complex. I really appreciate your video and shared it with my classmate
Hi sir well explained but i have small doubt. When ever oil goes through the orifice oil will split into the cylinder and also the split oil comes through the bypass check valve right?
Check valves are spring loaded so they will only be displaced if the pressure required to activate the cylinder is greater than the pressure required to unseat the check valve.
In his example there will also be hydraulic pressure on the ball side of the check valve keeping it from being displaced. When there is pressure in the supply line to both sides of the check valve the pressure difference will never be enough to open the check valve.
Hi sir.. Could you please explain.. For two clynders.. One is double acting and another single acting.. Using two throtle s/joy sticks... Thank you very much..
Hello KletteTech I have a question which I am very Confused about that. If a Pump is pushing flow rate of 5 Gpm, How to calculate the pressure in any particular part of the circuit? Thanks
GPM has little to do with pressure. The most important thing to remember is the a pump will create just enough pressure to create flow. Ill link a video for you in a minute
sir, thank u so much for great teaching. sir I have the one quatation, what is the different between bladder nitrogen accumlator and hyd. intensifier in hyd. circuit. Dhruvin Panchal
An accumulator storages energy for later use. The intensifier circuit increase the pressure greatly but distance is lost. The pressure can be increased to incredible amounts.
hello have a question, Need some help please I am wondering why there is no Filter in this hydraulic system? If there was one where would be the correct location before the pump or before returning to the tank?
Thanks for the question. In my schematic there is no filter because I did not draw it in. On the machine there is a filter built into the power unit but that is under the cabinet. If I were to draw a filter, I would place it on the return line for sure. When a system is filtered there is typically one on the return line. I hope this answers your question. If you have any more please let me know.
That is such a great question. Typically there is a filter symbol before the pump when there is a strainer in the tank. The strainer is attached to the pump's suction line. This is confusing because a filter and a strainer have the same symbol. So, that symbol between the tank and the pump is for a strainer in the tank. It is very hard to access because it is submerged in the oil.
A good explanation, but you should never use a closed center contol valve with a fixed displacement pump. In neutral position, when no work is done, the pump creates full flow at full pressure over the relief valve all the time. This creates heating of the oil and the system, consumes a lot of unnecessary energy and wears out the pump. With an open center control valve the oil has free passage from the pump through the valve to the tank. The same with flow control valves They create unnecessary load to the pump. Directional control valves are usually proportional, with them you can usually contol the speed of a cylinder pretty well.
Almost never. It would be redundant. You would only be controlling the speed in one direction. I have seen it done when very precise speed control is needed.
I like how simple you explain this schematic through moving symbols. I am changing from a fixed displacement to a pressure compensated variable displacement system on my boat and was wondering if you would be willing to view my schematic?
Sir i have doubt how can i construct a circuit for which i want to control speed on forward stroke with rapid return? Is this same thing as meter out during forward stoke?
That is a big question. I will say this, in my experience 90% of the all speed control circuits are meter out. I have only seen meter in a few time. Again that is my personal experience. I believe that most people think Meter out is safer and give better control. Although, many people say that Meter in is more energy efficient.
metering out on extension seems like you're building a pressure intensifier... looks dangerous. I think you definitely want to make sure there's a pressure relief on the rod end work port or you could blow up one of those lines or cylinders. Tee some gauges into the cylinder ports for an interesting demo. I like the white board magnet components!
It stops the cylinder's piston from slamming into the ends of the cylinders during retraction and extension. If I get a chance, I will make a video on it.
After watching some confusing videos finally someone who explained it perfectly , thanks a lot
Thanks. Glad it helped.
Yes true well said.
agree
2021 and I just want to say THANK YOU!!!! Finally, someone who explains all details, and not a weird robot voice yeahhhh
Good explanation for hydraulic function
2:22 It's the best explanation I have seen so far, thank you.
I used to teach this at technical College. This is a very clear and well paced explanation of fluid power principles of operation.
Thanks
Currently in school in Quebec in electromechanics and these videos are a life saver. Thanks for taking the time to post these to youtube, very informative! Going to share them with my class for sure.

Thanks for the great comment. I am happy this video helped
The only video which made me understand meter in and meter out :)...
Thanking for the 🎥...
Nice work and i see the commnets ..you are helping indian students more cuz they wanna know this by themselves
really amazing and u are right when u said metering is confusing
thanks a lot

this is one of the best explanation i've ever watched thank you sir ..
Glad it was helpful!
Very good teacher. Let’s say you want to automatically apply power to the control valve and have the cylinder keep retracting and extending. Will I need a limit switch at each end of the stroke and a linkage rod connected to the limit switches?
my left ear enjoyed it!
Glad to hear it.
Thanks a lot man. I thought I broke my headset...again
this is very understandable. ive never seen anything about metering ever, and i knew exactly what was happening by the time you got to the real life set up. and props to whoever made your magnetic marker board visuals. they are the mvp in this lesson. of course the guy talking helped a little bit...har har.

The Props are awesome
This is an awesome tutorial on fluid control.
You explained it clearly sir, esp those movable board demo. Well explained. You are truly a very good teacher to us. You really helps us. Thanks for this.
You are most welcome
The explanation couldn't be any better than this
Thanks man
You're welcome!
I say meter in on extension. The fluid pressure won't increase on the out side. Great explanations. Thanks.
For sure the explanation is one of the best which I saw till now, thanks :)
Thankyou professer
I have my automation exam tomorrow and got this concept clear with few Minutes
Thanks n love from India🙏🏻♥️
Awesome
Hello sir...
Can you tell me Variable flow control valve is two...
Means does it allow flow in both directions unlike check valve which don't allow in both directions...????
Easy to understand in schematic, little tricky to understand in practice.
Perfect mixture of theoretical practice and well presented subject
I am glad you liked it.
I wish NAIT can find this passionate instructor.
Thanks for the simplified working of meter-in and meter-out
Your Welcome
Very nicely explained both the circuits with the actual dac and valves
Thanks

Wow from this video i can actually clear my confusion on meter in & out....Thank you so much to making this video....
That is great. Glad it helped!
@@KletteTech sir it's seems that you have a very good knowledge about pneumatics and Hydraulics so i request you to please making video on types of valve and it's applications.
I will try
If possible please explain about meter in/meter out with PRV.
genuinely the best video i ever come acrossed, Thanks sir.
Wow, thanks!
Thanks Pat. You make that look easy. You were very thorough with your explaining and I love the visuals. Both board and hydraulic training box.
You're very welcome!

Best explained video I ever seen.. greetings from Spain
Wow, thanks! Greetings from Illinois USA
2022 This is amazing explanation please make more videos about hydraulics thank you
by metering in you could get springback, right?
One question sir? Wouldn't the oil go through the check valve and back to the speed control and solenoid valve as ones as you go meter in? just because speed control outlet port is connected to the check valve exhaust port. Please 🙏 explain. Awesome video and explanation though. Thank you sir.
creative way to explain the topic i really like it
Thanks
Thank you very much Mr. Klette . I learned a lot from your video .
That’s great. Thanks for watching.
So meter in your adjusting the flow that comes in. Meter out your adjusting the exhaust or flow that's going back to tank ?
correct
Can you make a video on Volume Boosters please? This video was awesome!
Best explanation that I found so far
Thanks
Thanks, it's very helpful. Just wondering whether you can do a video about how steering valve works(for example on a wheel loader).
If get time to put a video together on Steering Valve, I will.
Cool!
Big thanks sir from Saudi Arabia 🇸🇦🙏🏻🙏🏻🙏🏻♥️♥️
My pleasure
incredibly simplified with great visual reference. Thankyou!
Glad it was helpful!
You are a good teacher, thank you.
You are welcome!
Still the best video out there !! thanks sir !!
Wow, thanks!

Nice thank you ! Sir can u please explain me about flow amplifier in steering circuit
This video is very comprehensive. Thx
Glad it was helpful!
Excellent explanation with great clarity.Thanks for the same
Glad you like it. Thanks for the comment!
where did the magnetic display come from....i would like those to teach with
I believe I got those from Festo. They are nice to use. I prefer using them over teaching with a simulation program on many different topics.
Wow. Really excellent job explaining this. Thank you.
Thanks
Is the speed of the piston rod is same in both meter in retraction and meter in extension...
Will u reply ????
Excellent elaboration
thanks,sir can i know which place we use meter in and which place meter out
That is a big question. I will say this, in my experience 90% of the all speed control circuits are meter out. I have only seen meter in a few time. Again that is my personal experience. I believe that most people think Meter out is safer and give better control. Although, many people say that Meter in is more energy efficient.
THANK FUCK SOMEONE WHO CAN TEACH HYDRAULIC SYSTEMS, THANK YOU SO MUCH
what an awesome explanation !!!
Glad it was helpful!
Sir hats off your teaching process..best style specially showing with practical diagram..keep going.. subscribe your channel..😍😍👌👌👍👍🙏
Thanks and welcome.
Do you teach any full courses on Hydrolics? Or can you recommend someone who does?
I do at my college. I would check my local community college
metering out on extension seems like you're building a pressure intensifier... looks dangerous. I think you definitely want to make sure there's a pressure relief on the rod end work port or you could blow up one of those lines or cylinders. Tee some gauges into the cylinder ports for an interesting demo. I like the white board magnet components!
Meter out can be dangerous when there is a load that can overrun the cylinder. Lunch box sessions has a great video on it.
Love you sir ♥️♥️ You explained very well.
thanks
Great video, I understood it all perfectly. Please do make more videos on Pneumatic and Hydraulic circuits :)
Thanks, will do!
What is cushioning of cylinders?
It stops the cylinder's piston from slamming into the ends of the cylinders during retraction and extension. If I get a chance, I will make a video on it.
Thanks for meter in and meter out🙏😊
Thanks
I am confused. The first 12 min has no audio.
I think I recorded in mono on accident . Some people have said it only comes through on the left speaker
