Removing Actuator from Valve
Refer to Figure 6 for connecting parts identification.
Figure 6— Connecting Parts Identification
Flow in the pipeline with the actuator removed can slam the valve closed
causing personal injury and damaging the flow system. Shut down the flow in
the pipeline before removing the actuator from the valve.
1. Discontinue flow and relieve pipeline pressure.
When Eccentric Plug valves are mounted in a vertical pipeline, or mounted in a
horizontal pipeline with the plug stem horizontal, there is a chance that gravity
will cause the plug to swing to a lower position in the valve body when the
actuator is removed.
To avoid this hazard, rotate the plug to the lowest position before removing
the actuator.
2. Close the valve or rotate the plug to the lowest position in the valve body.
3. Remove the four adaptor mounting screws (P3).
4. Remove the actuator from the adaptor (P1).
5. Do not loose the drive key used in the valve plug and actuator gear.
