5 HANDWHEEL OPERATION
AQ actuators feature a handwheel for safety operation.
To avoid potentially harmful rotating protruding parts during
electrical operation, AQ handwheels feature a foldable handle: you
can fold it during electrical operation and unfold it if you need to
operate the actuator manually.
6 ASSEMBLY ON THE VALVE OR DAMPER
The actuator should be directly attached to the valve using proper
bolts or via a proper interface.
If the valve is in the closed position, then the actuator should also
be installed in the closed position. If the valve is open, so should be
the actuator.
If you cannot reach the correct position because you are blocked by
a mechanical stop, loosen the mechanical stop so that you have
enough space to go to the correct position.
After assembly on the valve or on the damper, the actuator can
operate in any position.
However:
• do not lift the actuator by the handwheel to avoid damage on
internal gearing.
• cable glands must not be oriented upwards (loss of water
tightness).
6.1 Changing closing direction visual indication
As a standard, AQ actuators are configured to close clockwise. If the
actuator must close counterclockwise, you can change the
orientation of the position indicator cap.
