Maintenance
WARNING
Always wear protective clothing, gloves, and eyewear when performing any maintenance procedures to avoid personal
injury or property damage.
Do not remove the actuator from the valve while the valve is still pressurized.
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.
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.
Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
