Understanding Directional Control Valve Schematics

[@bennettwolfe8140]

Brilliant!!! I never comment on content, but your account is full of light bulbs going off, so I have to say something. I'm attending a 6-month wind turbine tech school at the moment and we are on the hydraulic section now. We have a lab on campus with the hydraulic trainers and it all makes sense, however our teachers different styles are rudimentary and basically "your dumb if you don't understand this system' kind of vibe. After watching just one your videos it all clicked! especially the magnets having the different combos of DCVs. Teacher of the year award goes to you Sir. I'm going to supplement your videos for the schools videos and send your link to the rest of the students. Thanks heaps! -B

[@KletteTech]

Thanks for the compliment and thanks for watching. Please share. Hopefully it can help so more people.

[@kyralowry4708]

What do you do now? That sounds cool and I know it's been 3 years lol

[@aj6187]

You have just saved me 4 hours of readingz and practically saved my trade test. Thanks

[@KletteTech]

Glad I could help!

[@stephenoffiler8024]

I don't do pneumatics or hydraulics every day, but do run into problems I have to understand and correct every now and then. I have had to beat my way thru schematics in a slow, painful way, searching the Internet to fill in pieces of the puzzle. Now I find this video which explains literally everything I've ever needed on this subject in 16 minutes! Incredibly valuable.

[@KletteTech]

Thanks for the message happy the video helped.

[@sabastiondowns2176]

I never knew Justin Timberlake was so knowledgeable on directional control valves!!

[@daddy9132]

😂😂😂😂

[@KletteTech]

Haha

[@kyralowry4708]

Yea don't cry him a river then lol

[@jasonsmith5077]

This has helped me greatly. I have been tasked with installing a bunch of pneumatic vibrators using Mac 65 3/2 and I have been scratching my head. Thank you. I hooked all 63 up and they worked flawlessly the first go.

[@KletteTech]

That is awesome. Great job

[@y.t.s.794]

Thank you very much for making many useful videos. I am a hydraulic salesman and I found your website because I have to make an English presentation. English is not my mother tongue so it is really useful to listen to how you describe the basic knowledge in English.

[@KletteTech]

thanks for watching. I am really happy they help

[@dhh488]

I've always found this subject a little confusing, but you really did a great job of clearing things up for me.

[@KletteTech]

Glad it was helpful! I have a lot of other videos on this and other topics

[@whogavehimafork]

It suddenly clicked for me right at the 9:30 mark. I could almost physically feel that connection form in my brain. For whatever reason I haven't been able to comprehend these schematics but it all immediately made sense at that moment. The schematic itself IS the moving part. Thank you so much.

[@KletteTech]

Glad it helped!

[@Engineerboy100]

Good job on the video, thanks for the explanation. I'm a mechanical/aerospace engineer and just wanted to better understand the schematics on the valves. I still need to learn a bit more, but this was a very good start. Thanks again.

[@KletteTech]

Glad it was helpful!

[@frog6054]

[@utoobmann9083]

Thank you for this amazing free education professor! Trying to learn as much as I can about hydraulics to prep for an upcoming forklift mechanic interview, and this was gold.

[@KletteTech]

Glad it helped you out

[@therealalxmayhem]

Excellent video! I've been a purchasing agent for years, buying many of these types of valves. For the first time, I actually understand what I've been buying! :)

[@techofficetutorials2964]

Explained beautifully. Also explained hydraulic, solenoid and symbols which is rear in most of videos

[@mohammadnoormauludadnan1847]

thank you..... learn this the hard way 24 years ago, when I'm working as ground support at airport. All cargo pallets loader had hydraulic motor, ram, pump. a refresh for my new project.

[@KletteTech]

Well said

[@michellehc9230]

WAAAAAW!!!! Thank you A LOT, you have no idea how much this is going to help me. Some teachers take for granted that we know this stuff when in reality we don’t and that’s when we get to be left behind, thank you thank you thank youuu

[@KletteTech]

Glad it helped! And thanks for watching.

[@saisaranvenkata4299]

It was a clear and pleasant explanation of the valve notations. I appreciate how you explained the problems faced when using this notation on an industrial level.

[@KletteTech]

Glad you liked it

[@robertwalker8910]

I started a college class to advance at work. I am (struggling at) learning pneumatics and when he slid that magnet over, the whole class makes sense now!

[@KletteTech]

That is great. Good luck with your classes. Please share the videos with you classmates

[@robertwalker8910]

@@KletteTech The Final is in 2 weeks. If they fail, they cant blame us :) Because I have been telling everybody about your amazing explanations!

[@johnsantos975]

Sir, you did great and you did not go on and on, you were very precise and to the point. Your video delivered more than an hours worth of content in the span of 16 minutes. That is something that instructors and educators strive for. If you think you ramble look at other youtube videos and then reevaluate yourself and realize that you did a fantastic job.

Great work...i have a problem of a grader that has a steering fault. It uses the 4/3 spool valve and it has two solenoids as u drew that one and it indicates that the spool valve is not responding. What could be the problem? Cud it be the spring? Or one of the solenoids not working or dirt i the LS line?

WOW!!!! THANKS FOR THIS GREAT INTRODUCTORY LESSON!!! CAN YOU RECOMMEND A FEW GREAT TEXTBOOKS/WORKBOOKS ON READING AND UNDERSTANDING SUCH SCHEMATICS?!...

[@nnamdi9525]

Nice outline, very helpful. Please how do you distinguish between 5/3 DCV and 4/3 DCV. it's a bit confusing. Thanks.

[@KletteTech]

A 5/3 is used in pneumatics. It has an extra exhaust port.

[@evanb0869]

I’ve got a hydraulic power pack for torque wrenches that’s giving me problems and I’m trying to teach myself how to work on them. There’s a sticker on the side of one of the parts identical to one you’ve shown and explained. Really helped me to understand the system and what port does what

[@BROSKOIU1]

I have a problem with retracting rod of the boom cylinder at a new miniexcavator. It's pilot operated spool. I checked everything but the spool itself and the components. When retracting rod into cylinder it is an obstruction as it doesn't let bottom oil from cylinder to go freely back in the return line/tank. After 100 hours , this problem laminated my hidraulic oil and really broke his molecaular structure and turn it brownish dark (Iso VG46) and heats above 80 degrees celsius. Is it posible that somehow the joystick pilot pressure isn't enough to push the spool proper into corect position and the return line is chocked? Maybe the spool spring too stiff? Any help apreciatted. Thanks.

[@qlee5858]

So from a pressure standpoint for hookups, in order of highest to lowest, would it always have to be P, A, B, T? Meaning the arrows represent for direction?

yes. but there are a lot of factors in that questions. but in general yes
