Actuator Storage
For applications where the actuator is not put into immediate service it is recommended
that the actuator be cycled with regulated clean/dry pneumatic pressure at least once per
month. Indoor storage, if available, is recommended for all actuators. Care should be taken
to plug all open ports on actuator and controls to keep out foreign particles and moisture.
Also, actuators should not be stored in an atmosphere harmful to resilient seals. For
extended storage, contact the factory.

Actuator Installation
1.10.1
Since there are many valve and actuator combinations, it is not practical to include
detailed instructions for each type. Mountings are designed to be as simple as
possible to keep guess work out of installation.
1.10.2
Actuators are shipped from the factory with the travel stops adjusted for
approximately 90° rotation. Generally it is necessary to make slight travel stop
adjustments once the actuator is installed on the valve. Refer to the valve
manufacturer’s recommendations for specific requirements. When the valve has
internal stops, the actuator should be adjusted at the same points.
NOTE:
The actual “stopping” should be done by the actuator. If the valve does not have internal
stops, adjust the actuator to the full open position. Using this as a reference point, rotate the
valve until it’s closed and adjust to the valve manufacturer’s specifications for total rotation.
