3. Installation and Dismantling of the Actuator
Follow safety regulations
!
Note:
Check again whether the EA is place in accordance with the Chapter “Operation Conditions”. If
the installation conditions are different than recommended it is needed to consult the situation with the
producer.
Before starting the installation onto the valve:
•
Check again whether the EA was not damaged while storing.
•
Check compliance of the stroke adjusted by the producer and the connecting dimensions of the EA
with the parameters of the valve.
•
In case of any difference perform the adjustment according to the Chapter “Adjustment”.
3.1 Installation
The EA are adjusted by the producer to the parameters stated on the nameplate.
Put on the handwheel before assembly.
3.1.1 Mechanical Connection for Flanged Version
•
Defat the abutting areas of the connecting flange of the EA valve or the gear carefully;
•
Lubricate the output shaft of the valve/gear with a grease not containing any acids;
•
Set the EA to the limit position “closed”, set the valve to the same position;
•
Put the EA onto the valve with the output shaft reliably stalled in the valve coupling/gear;
Attention! Do not adjust EA on an armature forcibly because of damage of the gear!
•
Use the hand wheel to turn the EA to fit the openings in the EA and valve flanges if needed;
•
Check whether the connecting flange abuts with the valve/gear.
•
Fix the flange with four screws (with mechanical strength min 8G) fixed the way the actuator can
Be moved. Tighten the screws equally in cross.
•
At the end check the correctness of the fixture with the valve with rotating the hand wheel.
