Solenoid Operated Valves (Full Lecture)

[@mestrate]

Your series is brilliant and your ability to explain and transmit ideas and concepts is astounding. well done.

[@David-uj2ms]

How can you NOT like this? Great content. Thanks for taking the time to make such a detailed video.

[@robertobrenes5283]

I have been watching a few videos of your channel, and it is awesome!!! Cheers from Costa Rica

¡Qué chiva!

@@bigbadtech que bueno! Hablás español? I was looking for hydraulic diagrms help and found your videos! Do you know of any simple (and free hopefully) software to draw basic hydraulic diagrms? Or i have to do it on CAD?

[@bigbadtech]

Claro. I've used both FESTO's FluidSim and HydraForce's I-Design. I've also heard good things about Automation Studio. Everything I've done is hand drawn!

[@robertobrenes5283]

@@bigbadtech it looks nice to be hand drawn, and thank you, i'll check those software, i just want to draw a simple irrigation system, but i want to do a nice diagram btw, i love the intro in your videos jajaja

And thanks for you a lot Jim Pytel,, I am enjoying your videos and learning a lot, the way you are explaining every single point makes me very proud that their is amazing people like you in this world. God bless Jim, and keep it up.

Welldone Jim Pytel , HAVE being your active follower of your post at Columbia George college . Your detail lessons are explanatory and embracing even to fresher in the field. Thank you…

Hello Jim, I cannot find the lesson where You explained about DC and AC solenoid valve coil"s supply. That funny description with the lizard stuck inside the solenoid valve. Do You remember what was the exact lesson? Thank You in advance.

Simply the best

Thank you Jim! I think that solenoid coil may be damaged only if operated by AC current, when plunger is stuck. If solenoid is DC-operated, then coil will be safe. Am i right?

[@bigbadtech]

Yes, DC coils are known to have significantly reduced inrush because. Ironically enough often the problem with DC coils is when they're de-energized a brief voltage spike can occur because they're acting like an inductor with an established magnetic field that is collapsing. For this reason some DC coils include a "free wheeling" diode in parallel with the coil to dissipate this stored energy when de-energized. These types of coils are polarity dependent. I'll actually cover this phenomenon in detail when I introduce the inductor in between the DC and AC circuit analysis playlist.

[@RS_83]

Thanks, Jim! It would be great to make video about DC coil induction spike and diode protection. If you can, also add information about AC coil spike (MOVs, RC snubbers).
