Re: Motorizied flow control

As already mentioned the problem with your system is not the flow controls, but the 3-position valve.The question of using a 3-position valve to achieve intermediate cylinder positions has come up many times. If the center valve position is both-ports-closed, this technique is illegal because it creates closed, pressurized lines that are not vented when the system is vented. If the center valve position is both-ports-exhausted, this should be legal, but would have no ability to hold its position on its own.
