3.
Place coupling [1] onto valve shaft [2] and secure against axial slipping by using
a grub screw [3], a circlip or a screw [4]. Thereby, ensure that dimensions X, Y
or Z are observed (refer to figure and table <Coupling fitting dimensions>).
4.
Apply non-acidic grease at splines of coupling.
5.
Fit actuator.
Information: Ensure that the spigot (if provided) fits uniformly in the recess
and that the flanges are in complete contact.
6.
If flange bores do not match thread:
6.1 Slightly rotate handwheel until bores line up.
6.2 If required, shift actuator position by one tooth on the coupling.
7.
Fasten actuator with screws [4].
Information: We recommend applying liquid thread sealing material to the
screws to avoid contact corrosion.
→
Fasten screws [4] crosswise with a torque according to table.
