INSTALLATION
1. Before mounting actuator, verify that the torque requirement is less than the output
torque of the actuator. (The suggested safety factor is 30% of the max. torque of
valve.)
1.
For example :
If the maximum valve torque is 80Nm - 80 × 1.3(safety factor) =104 Nm
104Nm
＜
150Nm SEA 13 is
OK
!
104Nm
＞
90Nm SEA 8 is
not OK!
2. Check if the output shaft fits to the stem of valve before inserting into actuator. Please
use mounting plate or adapter to connect if it does not match.
3. Insert output shaft adapter into actuator. Make sure it fits satisfactory.
4. Determine that actuator position, open or closed, matches with position of equipment
prior to mounting. Use manual override to change position if necessary.
5.
Remove valve’s manual device and mount on the proper connection.
6. Check again that the valve and actuator are in the same position.
7. Install the actuator to valve directly or with mounting kits, then tighten all screws and
nuts.
8. Remove actuator cover.
9. Wire actuator using the wiring diagram inside cover.
10. Supply power to actuator.
11. Make sure if it is needed to calibrate the fully-open or fully-closed position of the
actuator.
12. If the actuator is modulating type make sure set the required settings.
13. Replace cover and secure cover screws.
