Assembly
Inspect the shaft: If it is damaged, it cannot make a good seal with the packing, and it must be replaced. If the leakage
comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches around
the packing box wall. Inspect the packing box wall for nicks and scratches when performing the following procedures.
If the valve is equipped with the ENVIRO‐SEAL packing system refer to the ENVIRO‐SEAL Packing System for Rotary
Valves instruction manual for assembly.
Note
Except with oxygen service, lightly lubricate new PTFE V‐rings with a silicone‐base lubricant to aid in assembly.
WARNING
Do not lubricate parts when used in oxygen service, or where the lubrication is incompatible with the process media. Any
use of lubricant can lead to the sudden explosion of media due to the oil/oxygen mixture, causing personal injury or
property damage.
