6. Fit part-turn actuator. If required, slightly turn part-turn actuator until splines of
coupling engage.
Figure 12:
Information
Ensure that the spigot (if provided) fits uniformly in the recess and that the flanges
are in complete contact.
7. If flange bores do not match thread:
7.1 Slightly rotate handwheel until bores line up.
7.2 If required, shift part-turn actuator by one tooth on the coupling.
8. Fasten part-turn actuator with screws.
Information: We recommend applying liquid thread sealing material to the
screws to avoid contact corrosion.
9. Fasten screws crosswise to a torque according to table.
