a. Remove the actuator mounting screws, bolts, or nuts.
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
shaft. Driving the lever or actuator off the valve shaft could damage the ball, seal(s), and valve.
If necessary, use a wheel puller to remove the lever or actuator from the valve shaft. Tap the wheel puller screw lightly to
loosen the lever or actuator. Do not hit the screw with excessive force. Using excessive force could damage the ball, seal(s),
and valve.
b. Slide the lever along the valve shaft while removing the actuator from the valve.
6. If necessary, remove the bonding strap assembly, shown in figure 2, from the valve before attempting to remove
the packing box parts.
7. Remove the packing follower nuts, packing flange, and packing follower (keys 101, 102, and 114, figure 3).
8. Remove the packing parts:
a. If the packing housing (key 16) is mounted on the valve: Use a formed wire hook with a sharp end to pierce the
packing rings, and pull the rings out of the packing box. Do not scratch the drive shaft or packing box wall.
Scratching these surfaces could cause leakage. Clean, inspect, and obtain replacement parts as necessary for
reassembly.
b. If the packing housing is removed from the valve: Remove the drive shaft (key 20) from the packing housing.
With the drive shaft removed, remove all internal parts. Clean, inspect, and obtain replacement parts as
necessary for reassembly.
The packing sets (key 105) listed in the parts list do not include any metal parts. Either clean and reuse metal packing
parts or obtain replacements by ordering them individually.
Assembly
If the valve is equipped with the ENVIRO‐SEAL packing system, refer to the ENVIRO‐SEAL Packing System Rotary Valves
instruction manual (D101643X012
) for assembly.
1. If the packing housing assembly (key16) is removed from the valve, use the valve assembly steps to reinstall the
drive shaft (key 20) and packing housing assembly on the valve.
2. For standard packing arrangements, install the new packing parts using the parts sequence shown in figure 3.
3. Secure the packing follower and packing flange with the packing nuts (keys 114, 102, and 101). Tighten the nuts far
enough to stop leakage during operating conditions.
4. If necessary, install the bonding strap assembly shown in figure 2.
5. Use the steps provided in the Actuator Mounting section to install the actuator on the valve. For actuator travel
adjustments, refer to the appropriate actuator instruction manual.
6. When the control valve is installed in the pipeline and in operation, check around the packing follower for leakage
and retighten the packing nuts as necessary.
Seal Ring Maintenance
Disassembly
WARNING
For valves with dual‐seals, fluid and/or a hazardous material may be trapped under pressure in the valve body cavity. To
avoid personal injury, relieve the pressure, and drain any remaining fluid or hazardous material from the valve body cavity.
If necessary, disassemble the valve in a safe area for cleaning.
