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.
