Jim - A very big and sincere thank you. I'm a 42 year old that has struggled with ADD most of my life (just recently diagnosed) and your teaching method helped me follow along and actually understand. I can't wait to see your other videos. Really, thank you! Chris in NJ
WOW wonderful video, im building a hydraulic press and needed a way to control it, this had just the right amount of info to make my machine greatings from mexico !
Thank You so Much Sir Jim...Now the next thing that I need to do is Hands-on for I'm done with the Theory already and that's all because of you. I've been following your videos on Hydraulics and it really helped me a lot..Great Teacher.
this great video sir jim,now im working in hydraulic company as a machinist and hydraulic technician,more on hands on troubleshoot now i want to know the theory especially on electrical....
Great video! Thanks. What is the advantage of a holding circuit as opposed to having your "on" switch (in the example at 35:00, "PB2") be a fixed-position lever that simply stays on or off?
@breedist Yes, on retraction, the oil from the cap ends would flow to the tank. The arrows in the schematic representation of the cross connected position aren't meant to imply "one way", you'd need a check valve to do that, they just mean "connect P to B and connect T to A".

You likely need another sequence valve in the rod end line of the clamp cylinder to keep the workpiece clamped while the press cylinder retracts. Don't know if unclamping and retracting the press cylinder at the same time is the best scenario.
I have been watching all of your training videos. Thank you. Is there a site where I can find all of them in order? Have you ever used fluid simulation software? Would love to see your drawings come to LIFE!
Hello Mr. Pytel I found some discrepancy in the last example.The flows from retraction of cylinders are going to stream where?Logically to the hydraulic oil tank but the arrow (Solenoid B) inside of the DCV is drawn inthe wrong direction Am I correct ?
Here's an updated example problem for electrically controlled hydraulic system on my other channel: th-cam.com/video/-kPDvNnMOcU/w-d-xo.html Expect major updates to this channel summer 2014. Long term I'm planning to include the whole basic electronics series, hydraulics, power electronics, control electronics, motors/generators, and renewable energy applications.

My education is so worthless. 2 years and it took a TH-cam video to explain this concept. Does anyone know where to get a QUALITY, career-oriented electrical education in/around Omaha, NE?

Great!! You just hit to the point where the question arises.
