Siemens SAX Electromotive Valve Actuator 500–800 N, 20 mm
Siemens SAX Electromotive Valve Actuator 500–800 N, 20 mm
The Siemens SAX series are electromotive actuators that position the valve stem with a linear movement. With 500–800 N positioning force and a 20 mm stroke, they drive seat control valves and pressure-independent valves.
The models in the series differ by supply voltage (AC 230 V or AC/DC 24 V) and control signal (3-position or DC 0…10 V / 4…20 mA modulating); the values for each model are given separately in the model table. Compatible valve series 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.
