I know these types of pneumatic systems very well and this is by far one of the best explanations on how a simple 5/2 single solenoid operated valve with spring return works. Great explanation. 👍
I love you guys, so much good explanation. Would take a who knows how long to imagine and to grasp all this Info. very well presented, each detail when and change of states in this valve control. Thank you for taking the time to make such a good explanation, especially with slow graphical presentations to follow change of states. Subscribed and staying here as well.
Thank you! Great to hear that! The format of the subtitles is not in our hands. You can adjust it in your own RU-vid account. Please do a quick google search and you'll find lots of videos about it.
This is INSPIRATIONAL , even i make INSTRUMENTATION VIDEOS I hope i can emulate your level of presentation one day !! All the very best and looking forward for more videos !!
I don't know it this is correct, but I also call these shuttle valves as the internal mechanism "shuttles" back and forth depending on the state of the solenoid.
Hey, John! Thanks for your comment. I believe it is better to use DCV, as Shuttle valves are used for different purposes. The concept is somehow the same, anyway.
Do you have a video explaining the hydraulic valve? We use them on steering for boats would love to the the internals and explaination of the return line
6:00 What if I use it in the reverse where my inputs are connected to ports 2 and 4 and the output is now port 1? ie, I want to feed it with 2 kinds of fluid and gets to select one?
At the 2:43 mark, isn't the lower left arrow pointing the wrong way in the diagram? Top and bottom arrows on left are both pointing inward on the valved.
Yes, as you explained, when the power is connected to the coil of the solenoid, an electromagnetic field will be created around it, and according to the right-hand law, it will create a force that pushes the spool to the opposite side (in this video, the right-hand side). When the power gets disconnected from the coil of the solenoid, the force will disappear and the spool gets back to its initial position by a force from the spring. Please let me know if my answer has solved your question.
@@Upmation hmmmmmm.....ok sir because in my mind just like a relay on eletronics or even some valves on automotive parts because I am an auto electrician sir when the coil has been flowed by the current it creates magnetism thats why causes valves,relays etc.to retract or being magnet that need for their functions....open and close....do you mean the magnetic flux surrounding on a coil instead of creating magnet it will push the spool valve?
@@Upmation ahhhhh.....now I know.....so how the other valves being magnet if that force is present? I mean their's a configuration,design? I thought only magnet will be on that energy....thank you sir....
As you've learned from the video, both have the same number of ports but a 5/2 valve has two positions, while a 5/3 has three positions. The third position of the 5/3 valve is for blocking all ports of the valve and the actuator will stop moving in this position. For instance, in this video if we had used a 5/3 valve, we could move the cylinder to right and left as well, but the difference with the 5/2 valve was that we could also stop the cylinder from moving in the middle of its movement to right or left. What we cannot do with a 5/2 valve. We will make a video about it.
