Thread: Dual Hydraulic Cylinder with One Control Valve

    Dual Hydraulic Cylinder with One Control Valve

    I am running in to an issue where we have a setup where we have one control valve to actuate two cylinders. I want to be able to have Cylinder 1 retract, cylinder 2 extend, and then once cylinder 2 extends, cylinder one would extend as well. Anyone know of any pressure relief or by pass valves to make this situation work? It would be just opposite for cylinder 2 when controlling the handle in the opposite direction. Cylinder 1 retracts, Cylinder 2 retracts, Cylinder 1 extends.

    Any help would be greatly appreciated!

    No way with only one valve. Once you have separate valves for each cylinder, and maybe some limit switches to detect extension and retraction, you can control them thru a program to do what you want.

    Yes, that's what I was thinking unless there is a specialty / propriety application.
    Tell me and I forget. Teach me and I remember. Involve me and I learn.
