Assembly
Information: Mount 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.
1. Thoroughly degrease mounting faces of output mounting flanges.
2. Apply a small quantity of grease to the valve shaft [2].
3. Use handwheel to run actuator to mechanical end stop.
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.
