PILOT VALVE ASSEMBLY
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).
