6. Mounting multi-turn actuators SA/SAR

When gearboxes and multi-turn actuators are supplied together, the mounting has

been done in the factory up to gearbox size GS 125.3. For sizes GS 160.3 and

larger, the mounting of gearboxes is performed as follows.

In case flange for actuator is not attached to gearbox or

reduction gearing:

Thoroughly degrease the mounting faces of the gearbox or reduction gearing as

well as the flange for actuator.

For GS 100.3 – GS 250.3:

Insert pin in the corresponding groove of the bearing cover.

Fit flange for actuator and fasten with bolts and lock washers.

Fasten bolts crosswise with a torque according to table 2.

Mounting the multi-turn actuator:

Thoroughly degrease the faces of the flange for actuator at the gearbox or

reduction gearing as well as the actuator’s bearing flange.

Place the multi-turn actuator on the worm gearbox or reduction gearing. The

multi-turn actuator can be mounted on the valve at every 90°

(see page 8, mounting positions).

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

worm 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 handwheel. 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.
