instructions. Figure 9 shows a typical HIGH‐SEAL Packing system. Figures 10, 11, and 12 show typical ENVIRO‐SEAL packing
systems.
If the valve has an ENVIRO‐SEAL bellows seal bonnet installed, refer to this manual. See the ENVIRO‐SEAL Bellows Seal and Bonnet
section for information on the bellows seal bonnet.

Packing Lubrication
Note
ENVIRO‐SEAL or HIGH‐SEAL packing does not require lubrication.
WARNING
To avoid personal injury or property damage resulting from fire or explosion, do not lubricate packing used in oxygen
service or in processes with temperatures over 260
_
C (500
_
F).
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 14, figure 8). 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, simply 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.
