8532 Valve

June 2017

The packing is now accessible.

3. Use a packing extractor to remove packing. Insert the corkscrew‐like end of the tool into the first piece of packing

and pull firmly to remove the packing. Repeat this process until all packing parts have been removed.

CAUTION

Be careful when cleaning the packing box. Scratches to the upper shaft (key 3) or inside diameter of the packing bore might
cause leakage.

4. Before installing new packing, clean the packing box.

5. Install new packing one ring at a time, using the packing follower as a driver. If using split‐ring packing, stagger the

splits in the rings to avoid creating a leak path.

6. Reinstall packing parts. Refer to figures 9 and 10 for sequence of packing parts.

Removing the Valve

1. Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open the valve. Vent the power actuator loading pressure.

2. Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process

pressure on both sides of the valve. Drain the process media from either side of the valve.

CAUTION

Damage to the valve disk can occur if the disk is not closed when the valve is being removed from the pipeline. If necessary,
stroke the actuator to place the disk in the closed position while removing the valve from the pipeline.
