This was extremely helpful. A sincere thanks for taking the time to put this together!

[@viettankhuu4668]

Thank you so much. Animation is the best way to explain engineering principles.

[@THELAZYGUYALOK]

good work. highly obliged for your effort.

[@sitinurfatihah9871]

Thank you. This is very helpful !

[@pratikpaul4753]

Very helpful video.thank you

[@neighboroldwang]

Really helpful. Thanks a lot.

[@souravdas-gz7sd]

All video is very good.

[@ActionMax09]

Awesome video.

[@kisanudyog-farmersmarket8642]

Thanks..... I think it's really good.....pls give videos on sequence valve and their circuit

[@pauljburgess7423]

Thanks so much for this!

[@RC-Heli835]

Would the PRV be the first place to look when I have a pay loader that has developed a very slow boom and bucket? Im talking snail slow.
Thanks

[@samlow4844]

Thanks for the video! How about a balanced bellow type and a conventional type PRV ? Are they under direct acting type?

[@vishveshpatel3932]

Fine explanation

[@flatbushtentcity]

Great video.

[@isabhiiii]

Thanks Man !! Tomorrow is my exam of Hydraulics and pneumatics .. it's very useful.. I've understand in juat 4:15 sec, which i haven't understood my whole semester 😹😹

[@ajayv304]

That's the beauty of our Indian Education system.

[@flamousz]

nice , very helpful

[@jasonburdette2419]

The symbol you used for the hydraulic pump is actually a symbol for a fixed displacement hydraulic motor.

Very good work with animation due to it EASy to understand

[@murugan91]

Thanks for shared the useful video...

Thank you !! Great 👍👍

[@cksahu606]

thanx dear

[@shammaris5011]

Nice, thank u

[@cck0728]

Very good video. I think you should have mentioned that main poppet has a metering hole that let the flow to the pilot valve, otherwise, the pilot valve will not operate.

[@ahmadabdullah5940]

how can i contact you

[@sonuyadav3927]

Sir plz kindly reqst h.. Forklift ke baare m khuch video upload kariye

[@shuklasunymech555]

very helpful video..please give some video on bursting disc too

[@mbd1415]

this spring is a linear type right?

[@jallajallu9948]

it's helpful to polytechnic students

[@k.j.renterprises5816]

Super sir

[@ruysanchez2587]

At the end of the video, it claims that a pilot operated advantage is its "Smaller Size" vs direct valves of the same pressure rating. However, it looks much larger. So, is it true that pilot operated are smaller in size? Or was this a mistake?
Would really like to know. Thanks.

[@top10arfani67]

nice

[@anikdas4452]

liked it.

[@user-vv9ud1ry9j]

please i need this simulation program you used for creat this video

[@MehediHasan-ku3po]

great

[@hisham031170]

Can POSV be used for steam application? Steam predominantly employs direct acting SV, there must be some reasons that POSV not used for steam.

Could you please tell me what kind of software you used to make this animation? Thank you very much!

[@n.s.agarage8084]

Did you manage to know the software used to make such animations

[@zhjichao]

N Seal Auto Engineering Sorry, I don't know yet.

[@speedfreak954]

I used 3D Studio Max for 3d modeling, animation and rendering. And then Adobe Premier for importing rendered footage, text, and video editing final video clips

[@PankajYadav-wo9gq]

Jab prv leckage ho To kya kare

[@HarshShah-xl6uk]

Please explain quick exhaust valve

[@baderajuformechanical1220]

Please explain pressure control valve in telugu

[@harishkate3123]

[@ADITYASHARMAACADEMY]

o ya realy good...............

[@Srk7028]

What is the benefit of pilot relief valve against direct acting relief valve ?direct acting is simple ,then what is the need of pilot relief valve.

[@gurucharanmunda1733]

👌👌👌👌👌👌

[@freddiemach1520]

I want to marry you.
No seriously, holy damn. This video is amazing. Thank you so much!

[@nathanhunnisett6199]

I believe that's a motor and not a pump
