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.
