Great info. Thank you.

Excellent

do you have info about how to test/diagnose LVDT Main's signal (b14, b16, z22)?

Hi , hope you are good. Wanted to know your views on Pressure reducing valves. When I checked, seems that they all have internal leakage through their pilot line. I mean , for a pressure reducing valve to work , the pilot line must drain oil to tank. So if any pressure reducing valve is connected to an accumulator, it will drain the accumulator till the preset pressure is reached and pilot drain flow will stop ! Am I right? Can pressure reducing valves be used with accumulators? For example, can we have a 3 way pressure reducing valve without internal leakage? Do we have any models of 3 way pressure reducing valves without leakage? Does leakage happen when valve is off ? For e.g suppose I have a 3 way proportional pressure reducing valve; when valve is off , output pressure is zero. If this valve is connected to an accumulator, will it drain all accumulator oil little by little? Will leakage occur when valve is off ? Thanks. Kind Regards.

With all due respect: the presenter emphasizes the use of safety glasses before and after the demonstration, but the instructor doesn't wear safety glasses during the demonstration. There is only one way to bring hydraulic safety out of the vacuum in which it lives: respectable companies like Motion Industries and Eaton MUST lead by example. May I also respectfully suggest that you emphasize how important it is to undertake a course in fundamental hydraulics and hydraulic safety before performing any type of work on hydraulic systems. "Hydraulic safety doesn't just happen. It must be vigorous pursued."
