Clover,you are a busy guyHey can I help you out with the pictures?? (Image hidden from quote, click to view.) (Image hidden from quote, click to view.) (Image hidden from quote, click to view.) Notice the "white" space between the pictures that I posted? I hit the enter key 3 times to bring the picture down and leave some white space,than I hit the Preview key to make sure it looked good.Not being picky,just easier to look at.
...In the event it is I will add in a pilot check valve. The description follows"Use to lock a hydraulic cylinder in one direction. It will hold up a load and prevent it from drifting down. Also prevents the load from falling if a hose fails. Place in between the directional control valve and cylinder. When the control valve is in neutral and the check closes the cylinder will be locked in position."
Thanks kbeitz. I was thinking of a single valve pilot just on the lowering side of the motor. They are a lot cheaper
Did some more research on the pilot valve and I'm not sure it would work in this situation. Basically what would happen is if a pilot valve opened at 75 psi but once the motor started to move the pressure would drop and the valve would close. It would chatter in a sense. Say I'm trying to slightly lower the head the pressure would not be high enough to hold the valve open so it would open and shut very quickly and chatter. I'm going to have to put some more thought into this for sure.
Thanks for the pictures DDW. How is the flow control plumbed? I've got a flow control on my mill but it will slow the flow of oil in both directions. I was going to just remove it as it is always wide open and I just feather the control valve to get the best cutting speed. On the return I pull back all the way.
There are many ways to get this head moving up and down.........
