Dear sır. It is a great video. I like to ask you a question. When the pressure rises in port A of clamping cylinder pres.reilef&reducing valve swich to tank from closed position. So the oil goes to tank from A port of the camp cly. If i dont misunderstand How come the clamp cyl. does not recract (moves backward) and unclamp the part. Other wise we will have vacum. Thank you for information before hand.
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.
