5. Assembly
5.1. Mounting position
The product described in this document can be operated without restriction in any
mounting position.
5.2. Actuator: mount to valve
The actuator is mounted to the valve using a coupling.
5.2.1. Overview on coupling variants
Design principle Figure 7: Coupling variants
[1] Bore with keyway
[2] Square bore
[3] Bore with two-flats
Application
●
For valve attachments according to EN ISO 5211
●
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].
