Electromotoric Actuators
CA1N4505en
HVAC Products
26.10.2006
These electromotoric actuators require no maintenance. They have a reversible
asynchronous motor which drives the main shaft via spur gears and a self-locking worm
gear, which accommodates the rectangular shaft of the butterfly valve. The worm shaft
is fitted with a direct-acting manual adjuster.
The actuators are supplied with a 90
°
angle of rotation suitable for use with Siemens
butterfly valves. During automatic operation, rotation is limited by two built-in end-
switches.
The direction of rotation of the actuator can be reversed (refer to
«
Commissioning
»
). To
prevent the temperature inside the housing from falling below the dewpoint temperature,
the actuators are supplied with a built-in heating element (AC 230 V, power
consumption 5 W).

In the presence of a 3-position signal, the auxiliary module
pulses the actuator. The output shaft rotates by approximately 2
°
with each pulse. The pulse-to-pause ratio is continuously
adjustable and can therefore be used to achieve longer running
times for an angle of rotation of 90
°
(refer to
«
Commissioning
»
).
Engineering notes
The actuators must be electrically connected in accordance with local regulations and
with the connection diagrams.
Regulations and requirements to ensure the safety of people and property must
be observed at all times.

These actuators must be used with the following mounting kit:
−
ASK35.1 or ASK35.2 for VKF46
…
butterfly valves
−
ASK35 for VKF41.150 and VKF41.200 butterfly valves
These actuators are mounted directly on type VKF46... butterfly valves. The butterfly
valves have to be closed during installation.
In case of unsteady ambient temperatures connect the built-in heating element to avoid
condensation.
The valve and actuator can be assembled straightforwardly on site. There is no need
for special tools.
