Replacing Packing

WARNING

Observe the warning at the start of the Maintenance section.

This section covers replacing packing used in plain and extension bonnets. PTFE V‐ring packing is shown in figure 3,
PTFE/composition packing is shown in figure 4, and graphite/ribbon packing is shown in figure 5.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the

process media from both sides of the valve. If using a power actuator, also shut off all pressure lines to the power
actuator, and release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures
stay in effect while you work on the equipment.

2. Disconnect the operating lines from the actuator and any leak‐off piping from the bonnet. Disconnect the stem

connector and then remove the actuator from the valve by unscrewing the yoke locknut (key 15, figure 11).

WARNING

To avoid personal injury or property damage caused by uncontrolled movement of the bonnet, loosen the bonnet by
following the instructions in the next step. Do not remove a stuck bonnet by pulling on it with equipment that can stretch
or store energy in any other manner. The sudden release of stored energy can cause uncontrolled movement of the bonnet.
If the seat ring retainer sticks to the bonnet, proceed carefully with bonnet removal.

Note

The following step also provides additional assurance that the valve body fluid pressure has been relieved.
