Positions of normally closed (PO-NC) and normally opened (PO-NO) and double acting (PO-DA) actuators
 For normally closed (PO-NC) actuators the butterfly valve has to be CLOSED

For normally opened (PO-NO) actuators the butterfly valve has to be OPENED

PO-DA (double acting) butterfly valve has to be set into the same position as the actuator. When
the actuator is set to the closed position, the butterfly valve must be set to the closed position
too. When the actuator is set to the opened position, the butterfly valve must be set to the
opened position too.
1.
Attach reducer onto the shaft
2. Connect the actuator to the reducer
3. Use tooth wheels and screws (4x) to fix the actuator with the cover plate and the body of the valve
4. Attach the four black caps
ATTENTION: Make sure the limit switch position is set correctly before commissioning.
This is important to ensure
 tightness,

correct opening and closing of the flap as well as

undisturbed operation (constant switching of the actuator could cause disturbance) of the
butterfly valve.
