Features
For the operation of Siemens 2-port and 3-port valves:
● Types V..G44.. and VVG55..
● 5.5 mm stroke
As control or shutoff valves in heating and ventilation systems.
Functions
Function Description Type
3-position control A 3-position signal drives the actuator via connection terminals Y1 or Y2. The
required position is transferred to the valve.
SAS31..
SAS81..
Modulating control The modulating positioning signal drives the actuator steplessly. The
positioning signal range (DC 0...10 V / DC 4...20 mA / 0...1000 Ω)
corresponds in a linear manner to the positioning range (fully closed...fully
open, or 0…100 % stroke).

Positioning signal
and flow
characteristic
selection
Setting the DIL switches.
Factory setting: All DIL switches set to “OFF”.
Position feedback U Signal used to acquire the position, fed back via an input.
Calibration During commissioning, the actuator detects the valve’s end positions and files
the exact stroke in its internal memory.
Detection of valve
seat
The actuators feature force-dependent valve seat detection. After calibration,
the exact valve stroke is filed in the actuator’s memory.
Detection of foreign
bodies
After detection of clogging, 3 attempts are made to overcome clogging. If the
attempts made are unsuccessful, the actuator continues to follow the
positioning signal within the restricted range only (LED continues to blink red).
Forced control Z
(Z mode)
Forced control serves for overriding automatic mode and is implemented in
the structure.
