The use of dry air increases the lifetime of the actuators, as well as the lifetime of their
accessories, solenoids and other pneumatic accessories.
4.2.1 RECOMMENDED MINIMUM AIR QUALITY
For best possible service life and trouble-free operation, ISO 8573-1 quality class 5.4.4
should be used. This means 40 µm filter, dew point +3ºC for indoor operation (a lower dew point
should be selected for outdoor operation, Quality class 3) and oil concentration 5.0mg oil/m³.

4.2.2 LUBRICATION
Actuators are factory lubricated for the lifetime in normal working conditions.
The standard lubricant is suitable for use from -30ºC (-22º F) up to 100ºC (212º F).
For low and high temperature execution, where special grease is required please contact
ACTREG.
For our standard execution we recommend to use Molicote B2.2 Plus grease or silimar.
WARNING !!
Actuators are lubricated during assembly and do not require any further lubrication.
4.3 Make sure that both the actuator and valve are in the same position, open or closed.
4.4 When assembling the actuator on the valve, check their alignment to ensure that the coupling parts
work perfectly aligned.
4.5 The coupling bolts, whether the actuator connects directly to the valve or uses a bracket, must be
tightened proportionally, distributing the stress, before tightening them completely.
4.6 The normal performance of the actuators is to close clockwise and to open anticlockwise.
However, this may be inverted under request.
4.7 ACTREG pneumatic actuators are provided with bi-directional pinion travel stops. Side located stops
allow a full ±5º travel adjustment between 85º and 95º. Adjustment of the counter clockwise and
clockwise rotation limits is accomplished by unscrewing the locking nuts. 1/3 turn of those locking nuts
means 1º of the stroke.
WARNING!!
Do not adjust more than 2.5º each side, designed by the manufacturer. Internal parts could
be damaged.
IMPORTANT !!
It is advisable to operate the actuator twice before fully tightening the coupling bolts in order to
ensure a good centring.
