Packing Disassembly
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, shut off all pressure lines (or other power
source) to the power actuator, release pressure from the actuator, and disconnect the pressure lines from the
actuator. Use lockout/tagout procedures to be sure that the above measures stay in effect while disassembling the
equipment.
WARNING
D See the WARNING at the beginning of the Maintenance section for more information before removing the valve from
the pipeline.
D Use proper lifting and rigging practices while moving the valve or valve/actuator assembly.
2. Remove line bolting, remove the control valve from the pipeline, and place the actuator/valve assembly on a flat
surface.
3. To assist with future reassembly, note and mark the orientation of the actuator with respect to the valve body and
the actuator lever orientation with respect to the valve drive shaft.
4. Refer to the appropriate actuator instruction manual for information on removal.
CAUTION
When removing the actuator from the valve, do not use a hammer or similar tool to drive the lever or actuator off the valve
drive shaft (key 20). Driving the lever or actuator off the valve drive shaft could damage the ball, seals, and valve.
