4. Assembly
4.1. Mounting position
The product described in this document can be operated without restriction in any
mounting position.
4.2. Actuator: mount to valve
4.2.1. Actuator for assembly: prepare
Prior to mounting, both valve and actuator must be in the same end position!
●
For butterfly valves, the recommended mounting position is end position
CLOSED.
●
For ball valves, the recommended mounting position is end position OPEN.
In compliance with the order, the actuator is supplied either in position CLOSED or
position OPEN. The mechanical position indicator supplies information on the set
position.
If the actuator position was not modified and agrees with the valve position, the
actuator can be mounted in the supplied position.
In case the actuator is in an incorrect position:
1. Operate the actuator into the same position as the valve via push buttons OPEN,
STOP, CLOSE while in motor operation. For motor operation, please refer to
<Actuator operation at the local controls> chapter.
2. Should the electrical connection not be available at the time of assembly, the
actuator can be operated into the required end position using the handwheel.
2.1 Turn the handwheel or the crank handle until the respective symbol
(OPEN/CLOSED) of mechanical position indication corresponds to the
mark (same end position OPEN or CLOSED as valve).
Information: Since the actuator is not equipped with internal end stops
(mechanical limits), the symbol should not be turned ahead of the mark.
2.2 Turn handwheel by approximately two turns (overrun) in the opposite dir-
ection.
After this procedure, the actuator can be mounted to the valve.
4.2.2. Output drive for coupling
Application
●
For valves with connections according to EN ISO 5211
●
For rotating, non-rising valve stem
Assembly
●
The actuator is mounted to the valve using a coupling placed onto the valve
shaft.
●
Unbored couplings must be adapted and machined to match the valve shaft
prior to mounting (e.g. with bore and keyway, two-flat or square bore)
