AUMA GK 10.2 - 5 Mounting Multi-Turn Actuators SA;SAR

5. Mounting multi-turn actuators SA/SAR
When bevel gearboxes and multi-turn actuators are supplied together, the
mounting can be done in the factory up to gearbox size GK 16.2, if desired.
For sizes GK 25.2 and larger, the mounting of gearboxes is performed as
follows.
In case flange for actuator is not attached to gearbox:
.
Thoroughly degrease the mounting faces of the gearbox and flange for
actuator.
.
Fit flange for actuator and fasten with bolts and lock washers.
.
Fasten bolts crosswise to the appropriate torque according to table 2.
Mounting the multi-turn actuator:
.
Thoroughly degrease the faces of the bearing flange at actuator and of
the input flange at bevel gearbox..
.
Place the multi-turn actuator on bevel gearbox.
The multi-turn actuator can be positioned on the valve at every 90°.
.
Ensure that the spigot mates uniformly in the recess and that the
mounting faces are in complete contact.
.
Fasten actuator with bolts and lock washers (see table 1) at the flange of
the bevel gearbox.
.
Fasten bolts crosswise with a torque according to table 2.
Do not attach ropes or hooks for the purpose of lifting the
actuator by hoist to the hand
wheel. If multi-turn actuator is
mounted on gearbox, attach ropes or hooks for the purpose
of lifting by hoist to gearbox and not to multi-turn actuator.
