amaged or worn valve parts can decrease performance and shorten
valve life.
Damaged or worn packing parts including the packing, spring, bear-
ings, and surrounding parts can cause a packing leak resulting in dam-
age to the actuator, accessories, and nearby equipment. Damaged or
worn packing parts can also cause increased hysteresis resulting in poor
control.
Damaged or worn trim parts including the plug, plug face, seat ring, seat
retainer, shaft, bearings, bearing seals, and drive pin can cause increased
hysteresis, poor control, excessive internal leakage, and poor shut-off.
Damaged or worn trim parts can also cause damage to the packing parts
resulting in a packing leak.
Damaged or worn body gaskets or o-ring seals can cause external leak-
age resulting in damage to the actuator, accessories, and nearby equip-
ment.
Should parts become worn or damaged, parts kits are available. Repack
Kits are available to replace the packing. Rebuild/Repack Kits are avail-
able to completely rebuild/ overhaul the valve. Warren Controls recom-
mends that the rebuilding of 3800 series valves be performed at the fac-
tory by qualified technicians with access to any required special tools
and techniques. Parts kits come with complete step-by-step instruc-
tions. Each kit has its own part number. Please provide the valve’s serial
number to ensure getting the correct kit part number and correct parts.
