    Parker Cartridge Valve, Anyone familiar with Parker stuff

    I found a valve on ebay for not too much.

    It's a Parker DF122C14

    This a proportional normally closed hydraulic valve,
    with more flow capacity than my tractor. It will need
    to be placed in some sort of manifold.

    The datasheet is below if anyone is interested.

    I used this data sheet to finish out a part number
    for this valve. But I get nowhere with internet searches.

    This is the number I selected. DF122 C14 D012 H P - A8T
    I basically wanted 12vdc, and then
    nothing that might be a special order item.

    Parker's website was a dead end.
    The companies huge, and I couldn't even
    find cartridge valves. They either no longer make
    these things, or this product is a rounding error for them.

    Parker-Surplus search was equally deadend.

    So, what I'm saying is, I have the valve, but I need the coil.

    Is it possible that these coils are made by second party companies
    and they're generic in some way? Does anyone know of a surplus
    or anyone who sells only coils and they'll know everything about coils?



    Anyway thanks. Probably bought another paper weight.

    Good luck Stone, I seriously doubt the coils are generic but I guess it’s possible.
    Buying thing like this on eBay is such a crap shoot, you may never know the full specs or intent or purpose of this valve...it could be from some now defunct top secret military project

    You should be able to get a local Parker distributor without too much trouble. Your gonna have to do some fiddling around to make a working setup on an open center system like your tractor has!

    Thanks Arlen.

    I'm going to try to find a Parker guy. I'm going to do some experimenting first.
    And it's hay making time now, so it will be later.

    I haven't studied this thing yet. But if it's a NC, 2 position valve, isn't that pretty
    much half of a valve you would need to move a cylinder back and forth? So
    you'd need 2 of these cartridges for in and out, or both directions. Couldn't you
    use a check valve to return the flow back to the P --- T pathway?

    I'm going to make a side view type drawing to explain what I'm asking.
    So, stand by, to stand by.

    Regards.

    The coils are listed on the last page in the "service parts" box, bottom left. I searched some of the numbers on ebay and came up with a few coils but they were either 120V or 24V.

    Thank-you.

    I guess the boxes to fill in are all for nothing.
    I was focusing on them.

    Glad it didn't bite me.

    Now I know to look for the arbitrary 'footnote' part number
    system. I should have known to read the notes, that's what
    kills you.

    I'll get busy and search for these.

    edit:
    I searched this P/N parker 851060-012VDC
    and found this. I thought the part number would help!
    It's very pricey! But it's one way. Or 'the' way!

    I am very familiar with Parker. The valve cartridge that you listed is a proportional valve. It is not just on/off like most solenoid valves. It will open proportionately meaning as you apply more milliamps to the coil, the further the valve will open.

    The coil that is used on this type of cartridge is designed to work with a milliamp (usually 4 - 20 milliamp) output controller, not just a on/off rocker or toggle switch.

    The coils for Parker valves are not made by a second party. They are Parker.

    I think you have to decide what it is you want to do first and then design the hydraulic system around what you want to accomplish.

    There is more to this than meets the immediate eye. Number one is, the type of control that is required to make this valve be proportional is not going to be a $20.00 component.

    I don't know what you are trying to control with your cylinder but I think it would be far easier if you selected an open center 4 way spool valve. These can be got self contained, so no extra manifold needed. If you wanted to control cylinder speed you could screw in one way adjustable flow controls.

    Thank you for responding.

    It took me quite a while to discover the things you've mentioned.
    And it's very nice to know or have some confirmation of what I
    thought I knew. Self education is a beeoch, and hit or miss for me.

    So thank you kindly. I'm waiting for some parts for this project,
    and I'm trying to get some hay made in between the storms.
