Packing Lubrication
These instructions are for the lubricator or lubricator
isolating valve (Figure 1). If the lubricator or lubrica-
tor isolating valve have been installed, they will be in
place of the pipe plug (Key 16, Figures 3 and 5) and are
designed for packing that requires lubrication, including
PTFE/composition. Jordan Valve recommends a silicon-
based lubricant. Lubricant is not recommended for
oxygen services or for processes that operate in excess
of 500F. To add lubricant to the packing box, turn the
capscrew in a clockwise direction.
For Lubricator/Isolating Valve
1. Open the isolating valve.
2. Turn the capscrew in a clockwise direction.
3. Close the isolating valve.
Packing Leakage
Spring-Loaded PTFE V-ring packing
To eliminate leakage, tighten the packing flange nuts
(key 2, Figures 3 and 5). If leakage cannot be controlled
in this manner, the packing will need to be replaced.
Other Packing
If packing other than Spring-Loaded PTFE V-ring has
been used, attempt to eliminate the leaking and create
a stem seal by tightening the packing flange nuts to the
minimum recommended torque given in Table 4. If leak-
age continues, the packing will need to be replaced.

Lubricator/Isolating Valve
New Packing
If tightening the appropriate flange nuts does not solve
the leakage problem and the packing is relatively new,
leakage could indicate damage to the packing box wall
or to the stem. Inspect the valve plug stem for a good
surface finish as well as the packing box wall for nicks
and scratches that could compromise the seal.
Hint:
If leakage originates from the outside diameter of
the packing, check the packing box wall for nicks or
scratches. If leakages originates from the inside diam-
eter of packing, check the stem for nicks or scratches.
