Function / mechanical design
The actuator is driven by a 3-position signal from the controller and generates a rotary
motion which is transferred via a driver to the valve.

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 endswitches.
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).

Auxiliary module
In the presence of a 3-position signal, the auxiliary module
4505Z10
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»).
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
SQL36E...
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.

Any Upright to horizontal
When commissioning the complete motorized valve consisting of actuator, mounting kit
and butterfly valve, always check the wiring and test the functions. This also applies to
any additional components fitted, e.g. auxiliary switch, potentiometer or auxiliary
module (variable positioning time).
VKF41… or VKF46... butterfly valves can only be commissioned with a SQL35.00 /
SQL85.00 or SQL36E… actuator or with an ASK46... manual adjuster fitted.
To avoid pressure shocks on the butterfly, the VKF46… must be driven to its fully open
position (either manually or via positioning signal Y1) prior to activating the pump(s).
The flow rate is adjusted either by driving the electric actuators as required, or by
operating the manual adjuster.
When using a SEZ31.1 auxiliary module set the desired positioning time:
SQL36E65: 30...180 s
SQL36E110: 60…360 s
SQL36E160: 120…720 s
«AUTO» = automatic operation
«MAN» = manual operation
SQL36E...
In the case of the SQL36E..., the manual adjuster is always engaged and cannot be
mechanically disconnected.
Direction of rotation

Every actuator must be driven by a dedicated controller (refer to «Connection

.
Maintenance
Caution
Disposal
Warranty
The actuators and butterfly valves require no maintenance.
Before performing any service work on the valve or actuator:
• Switch off the pump and power supply
• Close the main shut-off valves in the pipework
• Release pressure in the pipes and allow them to cool down completely
If necessary, disconnect electrical connections from terminals.
The valve must be re-commissioned only with the manual adjuster or the actuator
correctly assembled.
The actuator contains electrical and electronic components and must not be disposed
of together with domestic waste.
Legislation may demand special handling of certain components, or it may be sensible
from an ecological point of view.
Current local legislation must be observed.
The technical data given for these applications is valid only in conjunction with the
Siemens butterfly valves as detailed under «Equipment combinations». The use of thirdparty valves other than those recommended by Siemens invalidates the warranty.
