Siemens SSA161.05 Electromotive Valve Actuator 100 N, DC 0…10 V
Siemens SSA161.05 Electromotive Valve Actuator 100 N, DC 0…10 V
The Siemens SSA series are electromotive actuators powered at AC/DC 24 V with modulating DC 0…10 V control. With 100 N positioning force and a 6.5 mm stroke, they provide precise positioning on zone valves and pressure-independent valves.
The actuator mounts directly on the valve body; the valve series verified according to Siemens compatibility data are listed below.

This list is verified compatibility information based on Siemens product matching data; it is not a list of similar-product suggestions. You can make the final selection with our engineering team based on your project conditions (differential pressure, stroke, control signal).
Selection and installation notes
- The actuator's actuating force and stroke must match the close-off pressure and stroke of the valve it is fitted to.
- The supply voltage and control signal (3-position, DC 0…10 V or on/off) must match the controller output.
- Refer to the datasheet for mounting position and ambient temperature limits.
