Clean the valve body components in a parts clean-

any type of caustic solution. Dry the parts with com-
pressed air. Make sure all passages are clean and
free from obstructions.
NOTE: Do not use rags or shop towels to wipe off
valve body components. Lint from these materials
will adhere to the valve body components. Lint will

with a magnet). DO NOT polish or sand aluminum
valves or plugs with any type of material, or under
any circumstances. This practice might damage the
special coating and cause the valves and plugs to
stick and bind.
