WARNING
Avoid personal injury from sudden release of process pressure or uncontrolled movements 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 to avoid personal
injury.
D Disconnect any actuator operating lines providing air pressure, electric power, or a control signal to the actuator. Be
sure the actuator spring compression cannot suddenly open or close the valve. Vent actuator loading pressure.
D Use process 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. Use caution when handling
hazardous process media.
D Use lockout procedures to ensure that the above measures stay in effect while you are working 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 under pressure when removing the packing h ardware 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.
