Thanks for the video Carl’s Lunch Box Session.In your last session regarding pilot operated relief valve, you mention that you should change the 20 psi light spring of the main poppet if we put remote control relief valve.Keep safe always.
Interesting alternative option of control valve: sending pressure in neutral position to both sides to center the main spool, I don't heard before about it. Thanks Carl
No problem. In fact the larger Caterpillar excavators use that method - pressure to both sides of the spool to center, then reduce pressure gradually (proportional) on one side to allow the spool to shift.
I so sad that you haven't upoload for last 2 years,your content is the best educational video i have ever seen
Thanks man, greetings from Estonia!
LunchBox Sessions is goated
Thank you, great help since I have to learn all the hydraulic basics.

My question is,on what situation or condition we should change the light spring of the main poppet if we put remote control on the vent port? Thanks .
Good job you did make it easy for beginners to understand how does the internal parts of valve act's during operation.

Carl, then we are talling about "negative pilot signal" like some ancient valves in pneumatics. Thanks for asnwer
We have that in the Hydraulic Vibro hammer
if the solenoid is installed at sides of main valve will the high flow forces close the valve against weak solenoid force ? what will happen exactly
Muchas gracias por la información esta muy bien ilustrado 👍👍👍👍
Kindly upload videos regualarly.
Excelente! Aula mestre! muito obrigado.
Excellent thank you
We buy flash memory from you on interesting information
OK sir understood thank you!!!
