SIR , In the diagram of alpha lubricator block ,the inlet oil is shown on the tank line, is it like that or should it come to the pressure line of the solenoid operated valve from where it is distributed to tank line or to the operating piston as the valve switches .
The lecture was really informative and helpful. May I know for whom are these lectures being conucted? I mean is it for undergrad students or for Class 2/1 preparatory candidates?
