For valve attachments according to EN ISO 5211
For rotating, non-rising valve stem
Unbored couplings or couplings with pilot bore must be machined to match the valve
shaft prior to mounting the part-turn actuator to the valve (e.g. with bore and keyway,
two-flat or square bore).
Assemble valve and part-turn actuator in the same end position. As standard, the
part-turn actuator is supplied in end position CLOSED.
Recommended mounting position for butterfly valves: End position CLOSED.
Recommended mounting position for ball valves: End position OPEN.
1. If required, move part-turn 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].
