Lubrication of Actuator
For normal duty the Bettis GVO LP DA actuator is lubricated "for life".
In case of high load and high frequency of operation it may be necessary to periodically restore
lubrication: it is advisable to apply a generous coating of grease on the contact surfaces of
moving parts.
The following grease is used by Emerson for standard working temperature and suggested
for re-lubrication:
