5 Installing an electric rotary actuator
ATTENTION: Please choose correct ISO flange size for the DN150/DN200 butterfly valves
before ordering
ATTENTION: Keep in mind to use the right ISO flange size when connecting an electric rotary
actuator to the valve DN150/DN200.
For F07, an adapter plate is needed (without teeth).
For F10, a cover plate is needed (with teeth to engage the handle).
ATTENTION: Flap must close when turned clockwise and open when turned left!
1.
Check the position of the shaft hub. The hub always has to point to the 0° position of the cover plate
(closed position)
2. Assemble the actuator when closed (actuator on the very right so it can be opened to the left)
3. Attach reducer onto the shaft
4. Connect the actuator to the valve. Use tooth wheels and screws (4x) to fasten the actuator with the
cover plate and the body of the valve from below
5. 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.
