326L and 322L Lever Valves have self-adjusting packing and require no external adjustment. 326L and 322L Lever Valves with
stainless steel trim have TFE V-ring Packing. 322L Lever Valves with bronze trim have EPDM Lip Packing. If the valve has self-
adjusting packing and a packing leak is observed replace the packing and if necessary the stem and plug assembly.
PACKING ADJUSTMENT
Damaged or worn parts can decrease performance and shorten valve life.
Damaged or worn packing parts including as applicable the packing, bearings, spring, and other bonnet parts can cause
a packing leak resulting in damage to the actuator and surrounding equipment. Damaged or worn packing parts can also
cause increased hysteresis resulting in poor control.
Damaged or worn trim parts including as applicable the plug, stem, seat ring(s), piston, pilot retainer, and o-ring 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 can cause external leakage resulting in damage to the actuator, accessories, and surround-
ing equipment.
Should parts become worn or damaged, parts kits are available. Repack Kits are available to replace the packing. Repack/
Inspection Kits are available to allow the valve to be opened for inspection of its internal parts. Rebuild/Repack Kits are avail-
able to completely rebuild/ overhaul the valve. Parts kits come with complete step-by-step instructions. 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.
