Maintenance
WARNING
Avoid personal injury and property damage from sudden release of process pressure or bursting of parts. Before
performing any maintenance operations:
D
Do not remove the actuator from the valve while the valve is still pressurized.
D
Always wear protective gloves, clothing, and eyewear when performing any maintenance operations.
D
Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D
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 both sides of the valve.
D
Use lock‐out procedures to be sure the above measures stay in effect while you work on the equipment.
D
The valve packing box may contain process fluids that are pressurized,
even when the valve has been removed from the
pipeline.
Process fluids may spray out when removing the packing hardware or packing rings, or when loosening the
packing box pipe plug.
D
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Note
It is recommended that you review figure 2 before performing maintenance or installation of the CML electric actuator.
Recommended Installation Location
It is permissible to install the CML actuator upright or horizontally. Allow 12 inches of clearance for removal of the
actuator. Do not install with the actuator below the pipe.
CAUTION
To avoid equipment damage, do not install the valve with the stem in a downward position. Equipment damage may occur
from liquids leaking into the actuator cover.
