I have a piece of equipment that has two sets of spool valves with a bank of six on each. One of the banks of SV's has a valve/lever that is a bit prone to sticking and has to be manually returned to the neutral position. I have wondered if there is some kind of debris caught in the valve but it does not seem to pass. Never had this before and am not certain what the troubleshooting tree should be. Any of the hydraulic gurus got a direction for me to start looking. The valve seems to function normally otherwise except it tends to stick in both forward and aft positions and does not return to neutral.
