1.
Use handwheel to run actuator to mechanical end stop.
Information: Assemble valve and actuator in the same end position.
-
For butterfly valves: Recommended mounting position is end position
CLOSED.
-
For ball valves: Recommended mounting position is end position OPEN.
2.
Thoroughly degrease mounting faces of the output mounting flanges.
3.
Apply a small quantity of grease to the valve shaft [2].
4.
Place coupling [1] onto valve shaft [2] and secure against axial slipping by using
a grub screw, a circlip or a screw. Thereby, ensure that dimensions X, Y or Z
are observed (refer to figure and table <Coupling fitting dimensions>).
5.
Apply non-acidic grease at splines of coupling.
6.
Fit actuator.
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 actuator position by one tooth on the coupling.
