HEY guys ..look in2 the gist of the lecture ....its really appreciable . You may have to glean the facts from each and every book without his articulated lecture ..Dont mock these veterans being a naive !!!...anyways thanx 2 the knowledge sharing
While explaining the remote function of the relief valve (time 07.37) you have wrongly mentioned that pressure is applied from the remote side. It is the pilot pressure from the main relief valve which is either fully drained from the D C Valve (also called Vent Valve) as in your circuit or passed through another pilot relief valve always at a lower pressure than the main relief valve. In a tutorial lecture from an IIT this should have been avoided. Pl. make correction and upload.
Professor makes so many corrections and rough work on lecture sheet that the pattikular section stayed hidden and missed all the interest of the viewers.
man this guy got really confused with the pilot operated relief valve and he finaly explained it wrong haha, the valve has 3 ports not 4!!! so the moment when he hesitated was actualy right, both right and left ports are same (inlets), beside, when applying pressure to the pilot you're actulay shutting the relief valve NOT opening it as explained. so simply if you want to open the valve you must overpower EITHER the pilot pressure OR spring. other than that, great videos and thanx for posting =)
very, very nice job. you're helping many people...

I think the drawing of that pilot operated valve is wrong. thats the reason he's getting confused.
@risingfromashes1 lol r u trying to learn english from a engineering lesson ?
bogus...
