Posted for Scot Stambaugh <sstambaugh@qualcomm.com>:
Possibly a cleaner solution would be to use a flow restricter fitting in 
parallel with a check valve.  The fluid would have full flow in the direction 
that the check valve was open and the reverse flow would close the check valve 
and flow through the restricter orifice.  This way you don't have to do any 
sort of questionable modifications to a perfectly good (read expensive) check 
valve.  Seems like it would be simple plumbing, although a bit more space 
required.
Just one man's view of the problem.
