Hi, thank you so much for these great videos, I would like to ask, what is the copyright of this video. if I am gonna play some of them with coworkers?
Hi Amj! Thanks for your kind comment! Great to hear that you are enjoying our content! To answer your question, feel free to share this video with your coworkers! As long as our content remains unmodified and always linked back to RealPars. Happy learning!
This is really good video! One question, does flow direction matter(arrows)? because i don't see how it could unless the design of the seals or something like that pushes the valve sideways working against the solenoid, does this happen?
Yes, the flow direction arrows are very important. As the spool in the valve moves back and forth, specific flow paths are opened allowing flow in the directions shown. And yes there are seals that prevent backflow or flow to ports other than those in the current opened position. When the valve is de-energized, it is in a fixed position. Fluid can freely flow between the input and output according to the flow arrow. When the valve is energized, the spool is fixed in the other position. While there is some fluid pressure on the spool, there is not enough to affect the valve position in either state.
@@realpars "there are seals that prevent backflow" how would they prevent backflow? they had to have some sort of one way valve and while some may have this most do not right? "While there is some fluid pressure on the spool, there is not enough to affect the valve position in either state." If the pressure is not strong enough either way then why would it be a problem for fluid to go in the opposite direction? providing of course it has no form of one way valve.
Thanks for your support, Charlie! We are so happy to hear that you are enjoying our content. Let us know if you have any questions! We are more than happy to help!
Hello, can the direction of flow be switched? For example, in 3/2 DCV, the left arrow is only pointing up, can the flow go the opposite direction as well?
Technically, yes, but you really do not want to do so. Some solenoids (not many, but they do exist) have check valves in the outlet port. Secondly, if you reverse the flow direction, there will be fluid pressure on the "downsteream" port, which can counter the spring direction and pressure, and cause the valve to partially open (weep) or chatter without activation.
Hi Mohsen, Thanks for your comment. Regarding your question, I am actually not sure about that as this is done by our graphic and animation department.
Hola Jorge! Thanks for your comment! We currently only provide our course videos in English, you are always able to turn on the English subtitles as that might make it a bit easier for you. Our apologies for any inconvenience! Happy learning!
