MAINTENANCE
Continuous leakage from the exhaust port when the solenoid
is de-energized can be caused by a foreign particle trapped
between the bottom seat and the plunger, by a damaged bottom
seat, or by a worn or damaged bottom plunger seal. Leakage
at the exhaust port and/or solenoid buzzing when the solenoid
is energized can be caused by a foreign particle lodged in the
top seat area. Leakage in this area can also be caused by
worn or damaged top seats or top plunger seals.

NOTE: Most if not all problems are a result of a
foreign particle not allowing the ball to seat.
Cleaning of the seat area with WD40 or equivilent
and compressed air normally returns the valve to a
fully operational status.
Broken springs on spring return valves can cause a valve
to remain in the actuated position or to only partially return
and perhaps leak to exhaust. Broken springs must be replaced.
NOTE: The retaining nut on the top of each
hydraulic valve section requires only firm hand
tightening. Application of excessive force will result
in damage to the valve.
