To assemble the pilot valve, reverse the order of
disassembly. Should process fluid have contact with
the pilot valve o-rings, they should be replaced as
swelling may occur and cause irregular operation.
During assembly, ensure that the open side of the
lip-seals are facing outward. Lubrication of the pilot
sleeve assembly, with a non-synthetic lubricant, is
recommended in order to facilitate re-assembly into
the intermediate. Magna-Lube or Magna-Plate are
recommended for assembly lubrication (see detailed
parts list for ordering information).
