Hi Jarrett,
 
Actually, I believe that if the hose breaks anywhere the pressure will drop everywhere and the two cylinders will both lower (more or less) together.  I could be wrong about that, but until an hydraulic expert tells me otherwise, that is what my eyeball analysis indicates to me.

Ed, looks like you have it well in hand.. any plan however, for a hose break [or leak over time] which would lower one cylinder but not the other?

Good Idea, Lynn.  Screw the hose in one side of the aluminum block, up flow pushes through the restrictor and check valve, back flow closes check valve and only flows through restrictor.   Shouldn't be that hard to make.
 
Thanks
 
Ed

Not a bad idea, Ben.  They would slow down the opening a bit, but would probably slow down the closing even more.  I'll check into it.

Assemble a swing check valve in parallel with your restrictor. So, most of the up flow is unrestricted and any downflow closes the check valve and goes through the restrictor.
Or machine the whole thing in a small block of aluminum.
