Actuator Storage
For applications where the actuator is not placed 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. Actuators should not be stored in an atmosphere that is harmful to
resilient seals. Contact factory for extended storage period.

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 the guess work out of the installation.
1.10.2 Actuators that are shipped from the factory with the travel stops adjusted for
approximately ninety-degree rotation. Generally, it is necessary to make slight
travel stop adjustments once the actuator is installed onto 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 closed and adjust to the valve manufacturer's specifications for total rotation.
