Note
If the valve has ENVIRO‐SEAL live‐loaded packing installed (figure 4), see the instruction manual entitled ENVIRO‐SEAL Packing
System for Sliding‐Stem Valves, D101642X012, for packing instructions.
If the valve has HIGH‐SEAL Heavy‐Duty live‐loaded packing installed (figure 4), see the instruction manual entitled HIGH‐SEAL

Packing Lubrication

Note
To avoid lubricants breaking down at elevated temperatures, do not lubricate packing used in processes with temperatures over
260_C (500_F).
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.
If a lubricator or lubricator/isolating valve (figure 2) is provided for PTFE/composition or other packings that require
lubrication, it will be installed in place of the pipe plug (key 12, figure 6). Use a good quality silicon‐base lubricant.
Packing used in oxygen service or in processes with temperatures over 260_C (500_F) should not be lubricated. To
operate the lubricator, turn the cap screw clockwise to force the lubricant into the packing box. The
lubricator/isolating valve operates the same way except the isolating valve must first be opened and then closed after
lubrication is completed.
