3.2.2 Operating Temperature range

1. Using standard seals and greases the operating temperature range is -20°C to
+ 80°C (-4°F to +176°F) as is indicated on the product label.
2. Other medias and temperatures may be used but consult your local Emerson
sales office for confirmation as to suitability.

3.3 Maintenance

Before mounting or (dis) assembling the Actuator consult the relevant sections of
the installation, operation and maintenance manual for more detailed maintenance
information.
WARNING
Avoid personnel injury or property damage from sudden release of process pressure or
uncontrolled movement of parts. Before performing any maintenance operations:
„
Always wear protective gloves, clothing, and eye wear.
„
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.
„
Do not remove the actuator from the valve while the valve is still pressurized.
„
Vent any pneumatic pressure from the actuator and relieve any actuator spring
pre-compression.
„
Use lock-out procedures to be sure that the above measures stay in effect while you work
on the equipment.
„
Never apply pressure to a partially assembled actuator unless all pressure-retaining parts
have been installed properly.
„
Check with your process or safety engineer for any additional measures that must be taken
to protect against process media.
„
Do not remove the Pistons from the Actuator Body by using air pressure when the End Caps
have been removed.
CAUTION - PRESSURIZED ACTUATOR
„
Do not turn out the travel stops completely when the actuator is pressurized. When
adjusting the travel stops and the actuator is still pressurized, the travel stops can "shoot"
away when completely turned out.
