●
For rotating, non-rising valve stem
5.2.2.
Actuator (with coupling): mount
Unbored couplings or couplings with pilot bore must be machined to match the valve
shaft prior to mounting the actuator to the valve (e.g. with bore and keyway, two-flat
or square bore).
Assemble valve and actuator in the same end position. As standard, the actu-
ator is supplied in end position CLOSED.
→
Recommended mounting position for butterfly valves: End position CLOSED.
→
Recommended mounting position for ball valves: End position OPEN.
Assembly steps
1.
If required, move actuator in same end position as valve using the handwheel.
2.
Clean mounting faces, thoroughly degrease uncoated mounting surfaces.
3.
Apply a small quantity of grease to the valve shaft [2].
