AUMA Electric multi-turn actuators SA 07.1 - 48.1_SAR 07.1 - 30.1 NORM - Manual (Page 8)

We use the following packaging materials: wood, cardboard, paper and
Polyurethane foam. For the disposal of the packaging material, we recommend
recycling and collection centers.
5. Mounting to valve/gearbox
.
Prior to mounting the multi-turn actuator must be checked for
damage. Damaged parts must be replaced by original spare
parts.
.
After mounting, check multi-turn actuator for damage to paint
finish. If damage to paint-finish has occurred after mounting, it
has to be touched up to avoid corrosion.
Mounting is most easily done with the valve shaft/gearbox shaft pointing vertically
upward. But mounting is also possible in any other position.
The multi-turn actuator leaves the factory in position CLOSED (limit switch
CLOSED tripped).
.
Check if mounting flange fits the valve/gearbox.
Spigot at flanges should be loose fit!
The output drive types B1, B2, B3 or B4 (figure A-3) are delivered with bore and
keyway (usually according to ISO 5210) and are sometimes shipped with bore and
keyway according to customer request.
For output drive type A (figure B-1), the internal thread of the stem nut must match
the thread of the valve stem. If not ordered explicitly with thread, the stem nut is
unbored or with pilot bore when delivered. For finish machining of stem nut refer to
next page.
.
Check whether bore and keyway match the input shaft of valve/gearbox.
.
Thoroughly degrease mounting faces at multi-turn actuator and valve/gearbox.
.
Apply a small quantity of grease to input shaft of valve/gearbox.
.
Place actuator on valve/gearbox and fasten. Fasten bolts (quality grade 5, refer
to table 2) evenly crosswise.
