5.2.2.
Mount actuator (with coupling)
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].
