Problem: Cause: Solution:
Issues with the
actual control
valve: Contamination.
•
This valve is a precision device and is not intended for any
extensive field adjustment or repair. Field replacement parts
are limited to seal kits, cartridges, valve sections, and tie
rods.
•
Replacement of these parts, opening check cavities and
certain relief valve cavities to examine for trapped dirt, or
resetting the main relief valve with a good pressure gauge
should be referred to qualified service personnel.
•
Dirt and shreds of packing material are the usual causes of
valve malfunction. Be sure the oil reservoir supply is kept
clean.
•
Only genuine factory-supplied packings may be used in
cylinders. Everything must be clean and free of dirt during
the oil line removal, replacement, and cylinder work.
The inclusion of this information and its use does not imply that the warranty will remain
effective on the valve if it is tampered with during the warranty period.
