Don,

It seems highly unlikely that both sequence valves would display the same 
failure symptoms at the same time in a freshly installed system... not 
impossible, but unlikely.  The problem you're describing does sound like 
it's sequence valve related, but perhaps the valves are fine and there is 
another culprit.  The sequence valves are directional in that they need to 
be installed with a definite "inlet" side for the switch to operate 
properly and yet free-flow through as a check valve in the opposite 
direction.  Without opening one up I would say that the inlet (hi-pressure 
in) side is the port that is closest to the base of the valve, and the 
outlet (to the cylinder) is the port that is sort of centered on the 
opposite side.  I hate to second guess things from 150 miles away, 
especially after you've checked the hydraulic schematics and all, but 
that's the first thing I'd be looking at rather than thinking that the 
valves have failed.  Let us know what you find out.
